The Work Sharp E2 is my best overall pick among these electric knife sharpeners for its kitchen focused design and straightforward sharpening. For more control over edge angles, the Chef’sChoice 1520 handles both 15 and 20 degree edges, while the Work Sharp MK2 is the more versatile choice for knives and other tools. The main tradeoffs are how much control a sharpener gives you, whether it can handle serrated blades or scissors, and how much setup and practice it takes. A simpler two stage model may suit routine kitchen touch ups, while a multi stage sharpener can offer more options at the cost of added steps.

Key Takeaways
- The Work Sharp E2 leads this kitchen focused comparison; the MK2 models make more sense when sharpening tools is part of the job.
- Chef’sChoice 1520 and AngleSelect stand out for accommodating different edge angles, giving buyers more flexibility than a fixed angle sharpener.
- Stage count is not a quality ranking on its own. The two stage options favor a simpler routine, while three stage models offer a more involved sharpening path.
- Scissors and serrated knives narrow the field. Check for a dedicated slot or stated serrated blade support before choosing a general purpose model.
- Included replacement belts distinguish the MK2 bundle from the standard MK2, while both prioritize broader knife and tool use over a compact kitchen only design.

More Details on Our Top Picks
Work Sharp E2 Electric Kitchen Knife Sharpener
The Work Sharp E2 is the space-saving pick for cooks who want guided sharpening without learning to hold a precise angle. Its slots accommodate common kitchen knives, including serrated blades, giving it a broader kitchen role than the straight-edge-only Dawnstar S858. The compact countertop design also makes it easier to tuck away than the larger Chef’sChoice AngleSelect.
That simplicity comes with a narrower scope: the E2 is designed for kitchen knives, while the KAZRBEP 5-in-1 also lists scissors, axes, and other blade types. It requires an outlet, and the product details do not specify multiple sharpening stages or angle options. I’d choose it for routine kitchen upkeep and easy storage, but cooks seeking angle customization or a tool sharpener should look elsewhere.
Pros:- Guided slots reduce the need to control sharpening angle by hand
- Accepts chef, santoku, paring, and utility knives
- Works with serrated kitchen knives
- Compact design stores in a drawer or cabinet
Cons:- Requires an electrical outlet
- Limited to kitchen knives
- Product details do not specify multiple stages or adjustable angles
Best for: Home cooks with limited counter or drawer space who want guided sharpening for a mix of common kitchen knives
Not ideal for: Owners who want one sharpener for kitchen knives, scissors, and tools, or who need selectable edge angles
- Power source:Electric motor
- Compatible knives:Chef, santoku, paring, utility, and serrated kitchen knives
- Design:Compact countertop design
- Storage:Fits in a drawer or cabinet
- Sharpening guidance:Guided slots
- Intended use:Kitchen knives
Our verdict“Choose the Work Sharp E2 if compact storage and guided sharpening for everyday kitchen knives matter more than broad blade compatibility or angle selection.”
Chef’sChoice 1520 3-Stage Electric Knife Sharpener for 15- and 20-Degree Straight-Edge and Serrated Knives
The Chef’sChoice 1520 suits households with both 15° and 20° knives: its angle guides are made to sharpen and hone either edge, and the three-stage setup adds polishing disks for finishing. That flexibility gives it a clearer fit for mixed knife collections than the Work Sharp E2, whose listed details focus on guided slots and kitchen knife types without specifying angle options.
It handles straight-edge and serrated blades, including many American, European, and Asian-style kitchen knives. The tradeoff is a more involved process than the two-stage Dawnstar S858, and this model needs an outlet. At 10 × 4.25 × 4.25 inches and 4.2 pounds, it remains fairly contained, though it is less suited to buyers who want the broad extra-tool support listed for the KAZRBEP 5-in-1.
Pros:- Supports both 15° and 20° blade angles
- Three stages include sharpening, honing, and polishing disks
- Works with straight-edge and serrated knives
- Precision guides help maintain a consistent angle
Cons:- Requires electricity
- Three stages call for more steps than the two-stage Dawnstar S858
- First-time sharpening takes approximately one minute
Best for: Cooks maintaining a mix of 15° Asian-style and 20° American or European kitchen knives, including serrated blades
Not ideal for: Buyers who want a simple two-stage routine or a sharpener for scissors, axes, and other tools
- Brand:Chef’sChoice
- Model:1520
- Stages:3
- Abrasive:100% diamond
- Compatible blade angles:15° and 20°
- Compatible knives:Straight-edge and serrated
- Dimensions:10 × 4.25 × 4.25 inches
- Weight:4.2 pounds
Our verdict“Pick the Chef’sChoice 1520 if your kitchen has both 15° and 20° knives and you want guided sharpening with a polishing stage.”
Chef’sChoice AngleSelect 3-Stage Electric Knife Sharpener for 15° and 20° Knives
The Chef’sChoice AngleSelect is the broad-compatibility choice among these kitchen-focused sharpeners. Its three stages sharpen, hone, and polish, with support for 15° and 20° edges plus straight-edge, serrated, single-bevel, and double-bevel blades. That stated blade range goes beyond the Chef’sChoice 1520, which is listed for straight-edge and serrated knives at the same two angles.
Automatic knife guides help position blades, while diamond abrasives and flexible stropping and polishing discs handle the finishing steps. The extra range takes more space: at 12 × 6 × 6.4 inches and 4.9 pounds, it is larger and heavier than the 1520. Its three-stage process also involves more steps than the two-stage Dawnstar S858. This makes sense for cooks with varied blade constructions who are comfortable giving the sharpener a dedicated spot.
Pros:- Supports both 15° and 20° edge angles
- Listed for straight-edge, serrated, single-bevel, and double-bevel blades
- Diamond abrasives and flexible discs sharpen, hone, and polish
- Automatic guides help position knives
Cons:- Larger and heavier than the Chef’sChoice 1520
- Three-stage process involves more steps than the Dawnstar S858
- Requires an electrical power source
Best for: Cooks with a varied collection of 15° and 20° straight, serrated, single-bevel, and double-bevel knives
Not ideal for: Small-kitchen owners who want the most compact option or users who prefer a short, two-stage routine
- Brand:Chef’sChoice
- Model:0115207
- Stages:3
- Abrasive:100% diamond
- Supported edge angles:15° and 20°
- Compatible blades:Straight-edge, serrated, single-bevel, and double-bevel
- Dimensions:12 × 6 × 6.4 inches
- Weight:4.9 pounds
- Warranty:3-year limited warranty
Our verdict“Choose the AngleSelect if your knife collection includes varied blade styles and you can make room for its three-stage system.”
KAZRBEP 5-in-1 Electric Knife Sharpener with Scissor Sharpening
The KAZRBEP 5-in-1 is the lineup’s widest-use option: its listed compatibility includes straight and serrated knives, cleavers, ceramic knives, scissors, and axes. That range makes it a more versatile household tool than the kitchen-only Work Sharp E2 or the straight-blade kitchen focus of the Dawnstar S858. Three speed settings let users choose low, medium, or high, while the spring-loaded angle guide helps keep the blade positioned consistently.
It is not the simplest choice for someone who only maintains a chef’s knife. The product notes call for several passes per slot, and its plastic construction gives less emphasis to a substantial housing than the 4.2-pound Chef’sChoice 1520. A removable debris plate and ceramic polishing bar add practical cleanup and finishing options, but the listed sharpening angle is 20° with adjustment up to 32.5°, rather than the 15° and 20° support of the Chef’sChoice models.
Pros:- Listed for knives, scissors, cleavers, ceramic knives, and axes
- Three speed settings offer low, medium, and high operation
- Spring-loaded guide helps position blades
- Removable debris plate and ceramic polishing bar support cleanup and finishing
Cons:- Requires several passes per slot to sharpen a blade
- Listed angle range starts at 20°, so it does not match the stated 15° support of Chef’sChoice models
- Plastic construction may feel less substantial than the heavier Chef’sChoice 1520
Best for: Households that want one powered sharpener for kitchen knives, scissors, cleavers, ceramic knives, and axes
Not ideal for: Cooks maintaining 15° knives or anyone who wants a quick routine with minimal passes
- Brand:KAZRBEP
- Sharpening stages:3
- Speed settings:3: low, medium, and high
- Abrasive:Diamond
- Sharpening angle:20°; adjustable up to 32.5°
- Compatible blades:Straight and serrated knives, cleavers, ceramic knives, scissors, and axes
- Additional sharpening tool:Removable ceramic polishing bar
- Material:Plastic
Our verdict“Pick the KAZRBEP if you need one electric sharpener for varied household blades and can accept a slower, multi-pass process.”
Dawnstar Electric Knife Sharpener with Two Sharpening Stages
The Dawnstar S858 keeps the routine straightforward with coarse and fine stages for sharpening and polishing straight-blade kitchen knives. That simpler setup distinguishes it from the three-stage Chef’sChoice 1520, which adds support for serrated blades and both 15° and 20° edges. Magnetic metal-dust collection boxes are a practical touch: they gather sharpening debris to make cleanup easier.
Its 1.4-pound weight and 9.4 × 4 × 5.5-inch body also make it easier to move or store than the 4.9-pound Chef’sChoice AngleSelect. The narrower compatibility is the key tradeoff: the S858 is described for straight-blade kitchen knives such as chef’s, slicing, and santoku knives, while the KAZRBEP 5-in-1 covers a much wider range of tools. The first sharpening may take longer to shape the blade angle, so this is best for cooks who value a simple kitchen-only tool over broad blade support.
Pros:- Coarse and fine stages handle sharpening and polishing
- Magnetic collection boxes help gather metal dust
- Lightweight 1.4-pound body is easier to move and store than the AngleSelect
- 100–240V compatibility supports a broad range of electrical supplies
Cons:- Designed for straight-blade kitchen knives rather than a broad range of blade types
- First sharpening may take longer while shaping the blade angle
- Does not list the 15° and 20° angle support offered by Chef’sChoice 1520
Best for: Home cooks who maintain straight-blade chef’s, slicing, and santoku knives and want a light, simple two-stage sharpener
Not ideal for: Owners of serrated or non-kitchen blades, or cooks seeking selectable 15° and 20° angles
- Brand:Dawnstar
- Model:S858
- Sharpening stages:2: coarse and fine
- Voltage compatibility:100–240V
- Compatible knives:Straight-blade chef’s, slicing, and santoku knives
- Dimensions:9.4 × 4 × 5.5 inches
- Weight:1.4 pounds
- Material:Plastic
- Service policy:12-month replacement or refund policy and extended 12-month after-sales service
Our verdict“Choose the Dawnstar S858 if you want a lightweight, two-stage sharpener for straight-edge kitchen knives and can do without broader blade compatibility.”
TER 3-Stage Electric Knife Sharpener, Silver
The TER gives straight-edge kitchen knives a three-stage diamond sharpening path: restore a worn edge, refine it, then polish. Its fixed 20° angle suits many standard household blades, while a separate polishing slot offers a maintenance option for serrated knives. That makes it more versatile for a mixed kitchen drawer than the straight-blade-focused Narcissus QN-M866, though the TER’s serrated support is limited: those blades should use only the polishing stage.
A magnetic debris collector and non-slip feet help with cleanup and stability during pull-through sharpening. The tradeoff is less angle flexibility than the Work Sharp MK2, which offers 20° and 25° guides for knives and tools. Choose the TER for routine kitchen edges and light serrated maintenance; skip it if your knives need a different sharpening angle or more extensive serration repair.
Pros:- Three diamond stages handle restoration, honing, and polishing
- Separate polishing slot supports maintenance of serrated knives
- Magnetic collector helps contain metal debris
- Non-slip feet support stable countertop use
Cons:- Fixed 20° angle may not suit every knife
- Serrated knives should use only the polishing stage
Best for: Home cooks with standard 20° kitchen knives and a few serrated blades that need occasional edge maintenance
Not ideal for: Owners of knives designed for other edge angles or people seeking full sharpening of serrated blades
- Stages:3
- Abrasive:Diamond
- Sharpening angle:20°
- Color:Silver
- Dimensions:10.43 × 4.13 × 3.74 in
- Model:KSE3-02-Silver
- Included components:Electric knife sharpener, magnetic dust collector, user manual
- Warranty and support:12-month replacement or refund policy and 12-month after-sales service
Our verdict“Choose the TER for a straightforward three-stage sharpener that also offers limited polishing care for serrated kitchen knives.”
Hrevzon 3-Stage Electric Knife Sharpener with Diamond Abrasives
The Hrevzon’s main distinction is its stated compatibility with straight-edge, serrated, and ceramic knives, giving households with varied blade materials a broader target than the Narcissus QN-M866, which is designed for straight blades. Its three diamond stages move from coarse sharpening to fine refinement and polishing, so a dull edge can receive more than a quick finishing pass. The listing also describes serrated compatibility without the TER’s specific instruction to keep serrated blades to a polishing slot, though careful use still matters.
The pull-through method requires several backward draws, and heavily dulled blades may take around a minute, so this is not the fastest fix for neglected knives. Its 12.2-inch length also takes more counter or cabinet space than the compact Narcissus. A detachable magnetic collector and four silicone feet support tidier, steadier use. Pick it for a mixed household set; skip it if compact storage or quick touch-ups are the priority.
Pros:- Three stages cover coarse sharpening, refining, and polishing
- Listed compatibility includes ceramic and serrated knives
- Detachable magnetic collector supports easier cleanup
- Four non-slip feet help stabilize the unit
Cons:- Pull-through sharpening requires repeated backward draws
- Heavily dulled blades may take around a minute
- At 12.2 inches long, it is larger than compact two-stage options
Best for: Households maintaining a mix of steel, ceramic, straight-edge, and serrated kitchen knives
Not ideal for: Small kitchens or cooks who want a compact sharpener for quick touch-ups with minimal blade passes
- Sharpening stages:3: coarse, fine, and polish
- Abrasive:Industrial-grade diamond
- Compatible knives:Straight-edge, serrated, stainless steel, and ceramic
- Base:Four non-slip silicone feet
- Shavings collector:Detachable magnetic collection box
- Material:Metal
- Color:Black and orange
- Dimensions:12.2 × 4.9 × 4.6 in
Our verdict“Choose the Hrevzon if your kitchen includes ceramic and serrated knives and you can spare the counter space for a three-stage unit.”
Narcissus 2-Stage Electric Knife Sharpener with Scissors Slot
At 8.6 inches long and 1.6 pounds, this Narcissus is the easiest fit here for a crowded counter or a cabinet where a larger three-stage model would be awkward. Its coarse and fine slots cover basic sharpening and polishing for straight-blade kitchen knives, and the side slot adds a useful scissors-sharpening function. That gives it a different kind of versatility from the TER: the TER has three stages and limited serrated-knife polishing, while this model trades that extra stage for a smaller footprint and scissors slot.
The 30-watt motor and magnetic metal-dust box suit routine upkeep, but the stated design is for straight blades, so it is a poor match for a drawer full of serrated or ceramic knives. The manual also recommends reviewing the instructions and product video before first use. Choose this one for compact, basic kitchen maintenance; look to the broader Hrevzon if your knife collection includes more blade types.
Pros:- Compact 8.6-inch body and 1.6-pound weight suit limited storage
- Coarse and fine stages sharpen and polish straight blades
- Side slot adds scissors sharpening
- Magnetic collection box gathers metal shavings
Cons:- Designed for straight-blade knives rather than serrated blades
- Two stages offer less refinement than three-stage options such as the TER
- Instructions recommend reviewing the manual and product video before use
Best for: Apartment cooks who maintain straight-edge kitchen knives and want a compact unit that can also sharpen scissors
Not ideal for: Owners of serrated or ceramic knives, or anyone seeking a dedicated multi-stage system for several blade types
- Stages:2
- Motor power:30 W
- Input voltage:100–240 V
- Material:Carborundum
- Color:Silver
- Dimensions:8.6 × 2.6 × 2.9 in
- Weight:1.6 lb
- Included components:Adapter, knife sharpener
Our verdict“Choose the compact Narcissus if you mainly sharpen straight kitchen knives and want a scissors slot without a larger three-stage unit.”
Work Sharp MK2 Electric Knife and Tool Sharpener with Replacement Belts
This Work Sharp is the lineup’s tool-focused choice: flexible abrasive belts and a two-speed motor are designed for kitchen and pocket knives, scissors, axes, lawn mower blades, and other tools. Its 20° and 25° knife guides provide a choice of edge angles, unlike the fixed-angle TER and Narcissus S809. That flexibility is useful when one sharpener must serve both kitchen knives and workshop gear, but the broader setup also makes it less focused on simple countertop knife maintenance.
The included replacement belts give the owner spares for ongoing use, and the three-year warranty is longer than the 12-month policies listed for the TER and S809. The listed dimensions are compact, but the stated weight of 1.12 oz appears unusually low for an electric sharpener, so I would not use it to judge portability without confirming the product details. Choose this model for varied sharpening jobs; skip it if you only need a simple appliance for kitchen knives.
Pros:- Flexible belts support sharpening a wide range of knives and tools
- Two speed settings allow different sharpening approaches
- 20° and 25° knife guides offer angle choice
- Includes replacement belts and a three-year warranty
Cons:- Tool-oriented belt setup is less specialized for routine kitchen-only sharpening
- The listed weight of 1.12 oz appears unusually low and may need confirmation
Best for: Home cooks who also maintain pocket knives, scissors, axes, or lawn mower blades and want two speed settings
Not ideal for: Buyers seeking a dedicated, simple kitchen sharpener with clearly specified kitchen-focused stages
- Motor:Two speed
- Knife guide angles:20° / 25°
- Grit type:Medium
- Included components:Knife sharpener and replacement belts
- Material:Plastic
- Color:Black
- Dimensions:7.02 × 2.26 × 1.27 in
- Warranty:3 years
Our verdict“Choose the Work Sharp MK2 if one belt sharpener needs to handle kitchen knives and workshop tools at two speeds.”
Narcissus S809 3-Stage Electric Knife Sharpener
The S809 combines three diamond-abrasive stages with listed support for straight, serrated, stainless steel, and ceramic knives. That breadth makes it a stronger fit for varied kitchen drawers than the Narcissus QN-M866, whose two-stage design is specified for straight blades. A fixed 20° angle gives a consistent target for many household knives, and the removable bottom box collects metal dust. The open port also accommodates tools such as scissors and axes, though the listing does not describe it as a dedicated sharpening stage for those tools.
Compared with the TER, the S809 lists ceramic compatibility and tool access, while both use a fixed 20° angle and three-stage sharpening. That fixed angle is the main limitation: knives made for a different edge angle may not be a good match. The instructions also call for reading the manual before first use. Choose the S809 for a broad mix of kitchen blade types; choose the Work Sharp MK2 if adjustable guided angles and workshop-tool sharpening matter more.
Pros:- Three diamond stages cover repair, honing, and polishing
- Listed compatibility includes straight, serrated, stainless steel, and ceramic blades
- Fixed 20° angle supports consistent sharpening for suitable knives
- Removable bottom box collects metal dust
Cons:- Fixed 20° angle may not suit knives designed for other edge geometries
- Tool port is described for scissors and axes but lacks a detailed sharpening-stage specification
- Manual review is recommended before first use
Best for: Cooks with a varied kitchen knife set that includes ceramic or serrated blades and standard 20° edges
Not ideal for: Knife enthusiasts with blades designed for different edge angles or buyers who need a dedicated tool-sharpening system
- Sharpening stages:3
- Abrasive material:Diamond
- Sharpening angle:20 degrees
- Compatible blades:Straight, serrated, stainless steel, and ceramic
- Additional tool sharpening:Open port for tools such as scissors and axes
- Voltage:100–240 V
- Continuous operation:Over 1 hour
- Warranty and support:12-month replacement or refund policy; 24-month technical assistance
Our verdict“Choose the S809 for three-stage care across several kitchen blade materials when your knives suit a 20° edge.”
Presto 08810 Professional EverSharp Electric Knife Sharpener
The three-stage system and adjustable blade guides make this Presto a practical choice for households that sharpen both kitchen knives and sport knives. Its thickness selector helps accommodate different blades, while the extra-fine ceramic wheel gives the process a honing stage. Compared with the more compact Presto 08800, this model offers another stage and a broader stated range that includes hunting, fillet, and Santoku knives. The tradeoff is its listed footprint: at 18.43 inches long, it may take more storage space than a countertop-focused buyer wants. Suction-cup feet help keep it steady while sharpening, but it is limited to 120 V, 60 Hz power, which narrows its fit for international kitchens.
Pros:- Three stages add a honing step after sharpening
- Thickness selector and guides accommodate different blade profiles
- Designed for kitchen and sport knives, including hunting and fillet knives
- Suction-cup feet help stabilize the unit during use
Cons:- Listed 18.43-inch length can make storage awkward
- 120 V, 60 Hz power limits use in other electrical regions
Best for: Home cooks who also sharpen hunting, fillet, or Santoku knives and have room to store a larger sharpener
Not ideal for: Small-kitchen users or buyers outside 120 V, 60 Hz regions who need a compact or broadly compatible unit
- Brand:Presto
- Model:08810
- Sharpening stages:3
- Compatible knives:Kitchen, hunting, fillet, and Santoku knives
- Grit types:Light, medium, fine
- Dimensions:18.43 × 11.25 × 2.18 in
- Weight:5.1 lb
- Power:120 V, 60 Hz
- Warranty:1-year limited
Our verdict“Choose the Presto 08810 if you need adjustable guides and sharpening for both kitchen and sport knives, and can accommodate its larger footprint.”
Work Sharp MK2 Electric Knife and Tool Sharpener
The flexible abrasive belts set the Work Sharp MK2 apart from dedicated kitchen sharpeners: they can follow blade edges and handle a broad mix of knives and tools, including serrated blades, scissors, axes, and garden tools. Its two-speed motor gives users a lower or higher setting for different sharpening tasks. That range makes it a more versatile workshop choice than the kitchen-focused Chef’sChoice 15XV, which is designed around a 15-degree knife edge. The tradeoff is that belt sharpening requires replacement abrasives over time, and the plastic construction may feel less substantial than a fixed-slot appliance. Buyers who only need routine sharpening for straight kitchen knives may find the MK2’s broader tool capability unnecessary.
Pros:- Handles kitchen and pocket knives, serrated blades, scissors, axes, and garden tools
- Flexible belts can conform to different blade edges
- Two-speed motor offers control for heavier sharpening tasks
- Includes an edge guide and a 3-year warranty
Cons:- Abrasive belts need replacement as they wear
- Plastic construction may feel less substantial than a fixed-slot unit
Best for: Home cooks, gardeners, and outdoor enthusiasts who want one powered sharpener for knives and assorted edge tools
Not ideal for: People seeking a simple, dedicated kitchen sharpener who do not need belts or tool-sharpening versatility
- Brand:Work Sharp
- Model:WSKTS2
- Type:Electric knife and tool sharpener
- Motor:Two speed
- Included components:Abrasive belts, knife sharpener
- Material:Plastic
- Dimensions:7.02 × 2.26 × 1.27 in
- Warranty:3 years
Our verdict“Pick the Work Sharp MK2 if you want to sharpen outdoor tools alongside knives and are comfortable maintaining a belt-based system.”
Presto 08800 EverSharp Electric Knife Sharpener
The Presto 08800 keeps the sharpening routine straightforward: two stages grind and then hone most non-serrated kitchen and sport knives, while precision guides hold the blade at the sharpening angle. Its compact 8.25-inch length and nonslip base suit a kitchen where a sharpener needs to be easy to put away. Compared with the three-stage Presto 08810, the 08800 has a simpler process and smaller listed dimensions, but it does not offer the same stated range of blade types or an extra stage. The main limitation is blade compatibility: it does not handle most serrated knives, though one-sided serrated blades are listed as compatible. Its 120 V AC requirement also limits where it can be used.
Pros:- Two-stage system grinds and hones blades
- Precision guides help hold the sharpening angle
- Compact listed dimensions suit limited storage
- Nonslip base includes receptacles for metal filings
Cons:- Does not sharpen most serrated knives
- Requires a 120 V AC power supply
Best for: Home cooks who want a compact, guided sharpener for mostly straight-edge kitchen and sport knives
Not ideal for: Cooks with mostly serrated knives or buyers who need a sharpener for multiple voltage regions
- Brand:Presto
- Model:08800
- Type:Electric knife sharpener
- Sharpening stages:2 (coarse and fine)
- Compatible blades:Most non-serrated knives; one-sided serrated knives
- Voltage:120 V AC
- Dimensions:8.25 × 5.75 × 4 in
- Warranty:1-year limited
Our verdict“Choose the Presto 08800 for compact, guided sharpening of mostly non-serrated knives without the extra stage of the 08810.”
Chef’sChoice 15XV EdgeSelect 3-Stage Electric Knife Sharpener
The Chef’sChoice 15XV is the clearest fit for cooks who want to move traditional 20-degree knives to a 15-degree edge. Its three stages use 100% diamond abrasives to sharpen, hone, and polish, and the precision guides help keep the blade on the intended angle. It also handles straight-edge and serrated knives, giving it broader kitchen coverage than the Presto 08800, which does not sharpen most serrated blades. The tradeoff is that the fixed 15-degree result may not suit every knife or every owner’s preference. Buyers who want to preserve a 20-degree edge should compare it with the Chef’sChoice 1520, which supports both 15- and 20-degree knives. It needs an electrical outlet, as do the other powered options here.
Pros:- Three stages sharpen, hone, and polish
- 100% diamond abrasives are specified for the sharpening system
- Works with straight-edge and serrated knives
- Guides support conversion from a 20-degree edge to 15 degrees
Cons:- The 15-degree edge may not suit every knife
- Requires an electrical outlet
Best for: Cooks who want to convert compatible traditional 20-degree knives to a 15-degree edge and sharpen straight or serrated blades
Not ideal for: Knife owners who need to preserve a 20-degree edge or want control over more than one edge angle
- Brand:Chef’sChoice
- Model:15XV (0101500)
- Stages:3
- Abrasive:100% diamond abrasives
- Knife compatibility:Straight-edge and serrated knives
- Edge angle:15 degrees; converts traditional 20-degree edges
- Dimensions:10 × 4.25 × 4.25 in
- Warranty:3-year limited
Our verdict“Choose the 15XV if a 15-degree edge is your goal; consider the Chef’sChoice 1520 if you need both 15- and 20-degree options.”
Northmas Electric Knife Sharpener, 2-Stage, 100–240V, Blue
The Northmas is a small, two-stage option for buyers who need a sharpener that is easy to store and supports 100–240 V. Its coarse stage sharpens and its fine stage polishes, covering the basic sequence in a compact 7.8-inch body. That broad voltage range distinguishes it from the Presto 08800, which is listed for 120 V AC, while its modest footprint makes it easier to tuck away than the larger Presto 08810. The tradeoff is limited detail about blade compatibility and sharpening controls in the supplied product information, so it is a less specified choice for someone with specialist knives or exacting angle needs. Its instructions also call for guiding the knife against the slot wall, which may take adjustment for beginners.
Pros:- Coarse and fine stages cover sharpening and polishing
- Compact dimensions are suited to kitchen storage
- 100–240 V support broadens electrical compatibility
- Adapter is included
Cons:- Product information does not specify compatible knife types
- Instructions require positioning the knife against the slot wall while sharpening
Best for: Apartment cooks or international users seeking a compact two-stage sharpener with broad voltage support
Not ideal for: Buyers who need clearly specified compatibility for particular knife types or a guided angle system
- Brand:Northmas
- Model:QN-M868
- Stages:2 (coarse sharpening and fine polishing)
- Voltage:100–240 V
- Color:Blue
- Material:Plastic
- Dimensions:7.8 × 2.1 × 3.1 in
- Weight:1.2 lb
- Service:12-month replacement or refund service; 24-month after-sales service
Our verdict“Consider the Northmas if compact storage and 100–240 V support matter more than detailed blade compatibility information.”
How We Picked
I compared the 15 listed models by the features that change the buying decision: supported edge angles, number and purpose of sharpening stages, blade compatibility, and whether each unit can handle scissors or tools. I also weighed ease of setup, the likely learning curve, maintenance needs such as belt replacement, and how clearly each model is aimed at kitchen use.
The ranking favors sharpeners with a clear advantage for a common buyer need and a defined role in this lineup. The Work Sharp E2 ranks first as a kitchen focused option; Chef’sChoice models follow where angle flexibility or serrated blade support matters. Multi-purpose Work Sharp units suit buyers with tools to sharpen, while less differentiated two and three stage models rank lower when their listed features provide fewer clear reasons to choose them over the leaders. Each pick still has a tradeoff, from limited versatility to extra steps or a more specialized use case.

Factors to Consider When Choosing Electric Knife Sharpeners
Before choosing an electric sharpener, match its sharpening approach to the knives you own and the routine you will actually follow. These broader checks can help prevent buying more capability than you need or choosing a model that cannot handle an important blade.
Match the edge angle to your knives
Angle compatibility matters most when your knives already have a particular edge geometry or you want to maintain different knives in a consistent way. Models such as the Chef’sChoice 1520 and AngleSelect are designed around more than one angle, which can help in a mixed knife collection. A fixed angle option can be easier to use if your knives all share a similar edge and you want a repeatable routine. Do not assume that two knives with similar shapes use the same angle; manufacturer guidance is a better starting point. Changing an edge to match a sharpener may remove more steel than routine maintenance. If you are unsure, choose a model that supports your knives’ existing angles or consult the knife maker.
Choose stages for your sharpening routine
Stage count describes the machine’s process, not a guarantee that one sharpener will perform better than another. A two stage model may be a practical fit for regular upkeep, while a three stage design can separate steps such as sharpening and refining. The extra stages can give you more control over the process, but they also call for careful use and attention to the instructions. A common mistake is to run every knife through every stage at every session. Frequent heavy sharpening can remove steel unnecessarily, so reserve more intensive steps for when the edge needs them. Think about whether you need to restore neglected blades or mostly maintain knives that are already in good shape.
Check compatibility before buying
“Knife sharpener” does not automatically mean every kind of knife can go through every slot. Serrated blades, scissors, narrow blades, and specialty knives may need a dedicated feature or a different sharpening method. Some models in this lineup list scissors sharpening, and the Chef’sChoice 1520 lists support for serrated knives; those capabilities can matter more than a broad stage count. Read the maker’s compatibility guidance for the specific blade types you own. Forcing an unsuitable blade into a slot can produce a poor result or damage the edge. If most of your collection is specialty or serrated, prioritize clear blade support over a general purpose label.
Decide whether you need a kitchen or tool sharpener
A kitchen sharpener is usually the more natural fit when your main task is maintaining food preparation knives. Work Sharp’s MK2 models extend the use case to tools, which may appeal to someone who wants one powered system for several sharpening jobs. That added range can mean a different form factor and a process that asks for more familiarity than a basic kitchen unit. Avoid buying a tool oriented sharpener solely because it sounds more capable if you only maintain kitchen knives. Consider where you will store it, what materials you plan to sharpen, and whether the maker supplies suitable guidance and consumables. Broader use only adds value when you will actually use those extra capabilities.
Account for upkeep and consumables
Electric sharpeners need occasional cleaning and may use replaceable abrasive parts, so maintenance affects how convenient a model remains over time. The Work Sharp MK2 listing with replacement belts gives buyers a ready supply of a key consumable, while the standard MK2 listing does not name that bundle. Check what parts wear out, how replacements are obtained, and whether the instructions explain cleaning. Metal filings can collect around sharpening slots, so a tidy work area and routine cleanup help keep the unit usable. Do not treat a bundled spare as proof that a sharpener is maintenance free. A simpler unit may be the better fit if you prefer fewer parts and a kitchen only routine.
Pay for flexibility you will use
More stages, angle options, and blade types can justify choosing a more capable sharpener when they solve a real problem in your kitchen. A buyer with mixed edge angles may benefit from the Chef’sChoice options, while someone maintaining tools may have a reason to choose an MK2. If your knives share one angle and need occasional touch ups, added features can mean more steps without a meaningful benefit. Compare the capabilities against your actual collection rather than the longest feature list. It also helps to account for the learning curve: flexibility is useful only when you can apply it correctly. Choose the simplest model that covers your knives and sharpening habits.
Frequently Asked Questions
Can one electric sharpener maintain knives with different edge angles?
Some can, but the listed capabilities vary by model. The Chef’sChoice 1520 and AngleSelect are designed to work with 15 and 20 degree knives, giving them an advantage for a mixed collection. Before sharpening, check the knife maker’s guidance and the sharpener’s instructions for the blade in question. Avoid assuming a multi angle model supports every possible edge. If your knives differ widely, confirm compatibility for each one before buying.
Should I choose a two stage or three stage sharpener?
Base the choice on how you maintain your knives, not the stage count alone. A two stage option can suit routine upkeep when you want a more direct process, while a three stage model provides additional steps that may help when restoring or refining an edge. More stages also create more opportunities to use the machine when a knife only needs light maintenance. Follow the maker’s instructions on when to use each stage. If you are new to sharpening, a clearly explained process may matter more than the number of stages.
Can I sharpen serrated knives or scissors with these models?
Only if the particular sharpener lists support for that blade type or provides a suitable dedicated slot. The Chef’sChoice 1520 is described for straight edge and serrated knives, and some listed models include a scissors slot. That does not mean every slot is suitable for every serration pattern or pair of scissors. Check the product’s instructions before use, especially for specialty blades. If these items are a priority, make that compatibility a deciding feature instead of relying on a general purpose claim.
Is a tool sharpener a good choice for kitchen knives?
A multi-purpose sharpener can be useful if you plan to maintain both kitchen knives and tools, but the extra range may not suit a kitchen only routine. The Work Sharp MK2 models are positioned for knives and tools, while the E2 is more kitchen focused. Check the instructions for supported blade types and sharpening methods before using any tool oriented unit on a kitchen knife. Consider whether you have room to store the unit and are comfortable with its setup. If you only sharpen cooking knives, a kitchen specific model may be easier to match to that task.
How often should I use an electric sharpener?
Use it when the knife’s edge needs sharpening, following the intervals and signs described by the knife maker and sharpener instructions. There is no single schedule that fits every knife because use, cutting surfaces, and steel differ. Repeatedly using a sharpening stage on an already serviceable edge can remove steel without helping your routine. Keep sharpening and day to day edge care separate, and use the sharpener’s more intensive steps only as directed. If you are uncertain, start with the maker’s guidance rather than making repeated passes by habit.
Conclusion
For most kitchen buyers, I recommend the Work Sharp E2 as the best overall choice in this lineup. The Presto 08800 is a straightforward value pick for someone who wants a basic electric option, while the Chef’sChoice 1520 is my premium choice for buyers who need support for different angles and serrated knives. Beginners should look first at a kitchen focused model with a clear, simple process, such as the E2, and follow its instructions closely. Choose the Work Sharp MK2 if you also plan to sharpen tools; choose a model with a scissors slot if that is a regular task. The best fit depends on your knives, the edge angles they use, and how much versatility you will put to work.
