Best Knife and Scissor Sharpener: 10 Options That Handle Both Tasks
Most people own scissors they've been ignoring for years. The kitchen shears that used to cut cleanly through packaging and chicken skin are now struggling. And somewhere in the same drawer, there's a knife that hasn't been sharpened since they moved in.
A sharpener that handles both knives and scissors efficiently is the practical solution. You don't need a dedicated scissor sharpener and a dedicated knife sharpener if one tool does both jobs well. This guide covers the best options that handle both tasks, from $10 grab-and-go tools to $250 electric systems.
This is for home cooks who want to maintain their own tools without learning a complicated skill, and for gear enthusiasts who want more control over their edges across multiple tool types.

Product Reviews
AccuSharp White Knife Sharpener
The AccuSharp White is the foundation of a knife maintenance routine that costs under $11. At 27,368 reviews and 4.7 stars, it's one of the most validated inexpensive sharpeners available.
Three standout features: - Diamond-honed tungsten carbide blades for efficient material removal - Reversible sharpening blades that double the product lifespan - Works on straight-edge and serrated knives in about 10 seconds
This is the knife side of a two-tool approach. The AccuSharp handles kitchen knives, paring knives, fillet knives, and cleavers efficiently. The tungsten carbide removes material quickly, which is the mechanism behind the "10 seconds" claim. For maintained knives, this is accurate. Very dull knives need more passes.
Pairing this with the AccuSharp ShearSharp (reviewed below) gives you a complete knife-and-scissors maintenance system for about $20 total. Each tool is best-in-class for its specific task rather than a compromise that handles both tasks adequately but neither excellently.
The reversible blade design means when one face wears out, you flip it and continue. Most users report 5-10 years between blade replacement cycles, which is exceptional longevity for an $11 tool.
Pros: - Under $11 for proven tungsten carbide sharpening - Reversible blades for extended product life - Works on straight and serrated edges - 27,368 reviews validate quality at scale
Cons: - Knife-only, doesn't sharpen scissors (buy the combo or ShearSharp separately) - Fixed sharpening angle, no adjustment for Japanese knives - Removes more material per use than a honing rod
Work Sharp MK2 Professional Electric Knife and Tool Sharpener
The Work Sharp MK2 is the electric powerhouse in this roundup, handling knives, outdoor tools, scissors, and serrated blades with adjustable belt sharpening.
Three standout features: - Flexible abrasive belts that conform to blade edges including serrations and curved profiles - Two-speed motor with edge guide that supports the knife through the tip - 3-year warranty from the Work Sharp brand with Oregon-based quality control
Belt sharpening is fundamentally different from the pull-through abrasive approach. The flexible belt conforms to the blade edge and produces a continuous convex grind rather than a V-grind. This produces an extremely durable edge because there's no single thin point of the "V" to chip. For outdoor tools like lawn mower blades, axes, and hatchets, belt sharpening is the practical standard.
For scissors, the belt provides more control over the sharpening angle than most manual sharpeners, which is important because scissors require sharpening only on one face of each blade, not like a double-bevel knife edge.
At $89.95 with 8,008 reviews at 4.7 stars, this is well-validated professional-grade equipment for a home price. The two-speed motor lets you choose between aggressive material removal for dull tools and gentle honing for maintenance. The 3-year warranty from an Oregon-based company suggests confidence in the product's longevity. This is a core recommendation alongside the knife sharpener options I cover for dedicated kitchen use.
Pros: - Flexible belt sharpening for knives, tools, and scissors - Two-speed motor for different sharpening needs - Edge guide supports knife through the full blade length - 3-year warranty with Oregon quality control
Cons: - $89.95 is the highest price tier in this roundup (outside Ken Onion variants) - Requires some learning to use optimally - Belt sharpening removes more material than honing
AccuSharp Knife Sharpener + ShearSharp Scissor Sharpener Combo
The AccuSharp + ShearSharp combo at $19.99 is the best value entry for buyers who specifically want both a knife sharpener and a scissor sharpener in one purchase.
Three standout features: - Two dedicated tools: AccuSharp knife sharpener and ShearSharp scissors sharpener - Diamond-honed tungsten carbide in the knife sharpener, carbide in the scissors tool - Both tools are reversible and dishwasher-safe for easy maintenance
The ShearSharp is a separate tool from the AccuSharp knife sharpener, not an integrated multi-function unit. This is actually an advantage. Each tool is optimized for its specific task. The ShearSharp uses a dedicated carbide blade angled specifically for scissor sharpening, running along one face of the scissor blade at the correct geometry. The AccuSharp uses its standard double-bevel carbide for knife work.
At $19.99 for both tools with 5,781 reviews at 4.7 stars (across the combo), this is the most practical value option in this guide. General-purpose scissors, kitchen shears, hedge clippers, and tin snips all work with the ShearSharp. The AccuSharp handles all knife types.
This is the kit I'd recommend for a friend who wants to start maintaining their kitchen tools but doesn't want to spend money on an electric system.
Pros: - Dedicated tools for each task, both optimized for specific use - $19.99 for both sharpeners together - ShearSharp works on kitchen shears, scissors, and tin snips - Both tools are reversible and dishwasher-safe
Cons: - Two separate tools to store and manage - Fixed sharpening angles for both tools - Scissor sharpening with the ShearSharp requires some technique
Chef'sChoice 15XV EdgeSelect Professional Electric Knife Sharpener
The Chef'sChoice 15XV is a premium 3-stage electric sharpener specifically designed to convert 20-degree factory edges to 15-degree high-performance edges.
Three standout features: - Converts traditional 20-degree factory edges to 15-degree Trizor XV edges - 100% diamond abrasives in all three sharpening stages - Advanced patented flexible spring guides for automatic angle control
The edge conversion capability is unique in this roundup. Most sharpeners maintain whatever angle the knife was ground to. The 15XV actually reshapes the edge geometry to a finer 15-degree angle on the first use, then maintains that new angle in subsequent sharpenings. For cooks with German-style 20-degree knives who want Japanese-style 15-degree sharpness without buying new knives, this is the tool.
The diamond abrasives across all three stages are important quality indicators. Stage 1 uses coarse diamonds for edge setting and conversion. Stage 2 uses fine diamonds for sharpening. Stage 3 uses diamond-embedded strop for polishing. Diamond abrasive maintains consistent cutting ability over thousands of cycles, unlike ceramic or carbide that degrades.
At $143.62 with 14,107 reviews at 4.6 stars, this is the most-reviewed electric sharpener in this guide. The slight lower rating compared to the manual options reflects the learning curve for edge conversion and the higher bar of expectations at this price.
Note: this sharpener handles knives, not scissors. It's included because many buyers searching for knife and scissor sharpeners ultimately want a premium knife sharpener and a separate scissor solution.
Pros: - Converts 20-degree edges to 15-degree for higher performance - 100% diamond abrasives for consistent results over thousands of cycles - 14,107 reviews provide extensive validation - Flexible spring guides for automatic angle positioning
Cons: - Does not sharpen scissors despite being in this category - $143.62 is a significant investment - Edge conversion is one-way, can't easily restore original 20-degree angle
Work Sharp Ken Onion Knife Sharpener Tool MK2
The Work Sharp Ken Onion MK2 at $169.95 is the expert-level belt sharpening system co-designed with renowned knife maker Ken Onion, delivering professional precision for serious edge enthusiasts.
Three standout features: - Designed with knife maker Ken Onion for expert-level precision and keen edges - Flexible abrasive belts with precision sharpening guides for consistent results - Electronic speed control for adjustable belt speed across different materials
Ken Onion is one of the most recognized names in the custom knife world, and his involvement in this product means the design choices reflect actual knife-making expertise rather than just engineering optimization. The edge guide system is designed to produce "incredibly keen edges" with consistent results on every pass.
Electronic speed control is a meaningful differentiator from standard electric sharpeners. Different materials benefit from different belt speeds. Harder steels need slower, more controlled material removal. Softer steels can tolerate faster passes. The control gives you that flexibility.
At $169.95, this is serious investment territory. The 787 reviews at 4.6 stars are solid but represent a more specialized buyer pool. This tool is for people who maintain multiple knives regularly and want professional-grade results at home. The knife set guide covers how investment in sharpening relates to knife set longevity.
Pros: - Ken Onion collaboration for authentic knife-making design input - Electronic speed control for different material needs - Precision sharpening guides for consistent angles - 3-year warranty
Cons: - $169.95 requires genuine commitment to knife maintenance - Smaller review count (787) than the standard MK2 - Overkill for casual home cooks
Work Sharp Ken Onion Elite MK2 with Blade Grinding Attachment
The Elite MK2 at $249.95 is the ultimate version of the Ken Onion system, adding a Blade Grinding Attachment for full custom grind control and larger belt surface.
Three standout features: - Two modes: Sharpening Guide Cassette for knives/scissors/tools, and Blade Grinding Attachment for custom grinds - Larger belts with wider angle range on the Blade Grinding Attachment - Profile control for edge geometry customization beyond standard sharpening
The Blade Grinding Attachment is what separates the Elite from the standard Ken Onion. Custom grinds allow you to reshape a blade's geometry entirely, not just resharpen an existing edge. This is how knife makers create specific edge profiles for different purposes. For home cooks, this level of capability is unnecessary. For serious knife hobbyists and people who want full control over their tools, it's compelling.
The ability to switch between modes without tools or complicated setup makes this practically more flexible than a professional grinding setup. At $249.95, this is at the boundary of what a serious home cook would spend versus what a small-scale professional would spend.
Pros: - Two-mode system handles both standard sharpening and custom grinds - Ultimate flexibility in edge geometry control - 3-year warranty - Mode switching without tools
Cons: - $249.95 is significant for most home use cases - Custom grind capability is overkill for typical kitchen maintenance - Smaller review count (787 across Ken Onion models)
AGRILIA Premium Knife Sharpener with Adjustable Angle Knob
The AGRILIA at $24.99 is a manual sharpener with an adjustable angle knob (14-24 degrees) plus a dedicated scissor slot, and it includes a bonus chef's knife.
Three standout features: - Adjustable angle knob from 14 to 24 degrees for different knife types - Three-slot design with tungsten alloy, ceramic, and diamond abrasives - Dedicated slot for scissors plus adjustable slots for knife types
The adjustable angle is the feature that separates this from fixed-angle pull-through sharpeners. Being able to dial in 14 degrees for a Japanese knife and 20 degrees for a German knife in the same tool is genuinely useful for households with mixed knife collections. The 14-24 degree range covers essentially every common kitchen knife angle.
The three different abrasive materials (tungsten alloy for coarse, ceramic for fine, diamond for ultra-fine) provide a staged sharpening process within one compact unit. The included chef's knife is a bonus, though I'd view it as a freebie rather than a consideration in the purchase decision.
At $24.99 with 145 reviews at 4.6 stars, the small review count is the limitation. The concept and specs are genuinely appealing. A manual sharpener with adjustable angle and scissors capability at $25 would be exceptional if the build quality holds up across more users.
Pros: - Adjustable angle knob covers 14-24 degrees for all knife types - Three abrasive materials for staged sharpening process - Dedicated scissor slot in the same unit - Includes bonus chef's knife
Cons: - Very small review count (145) limits confidence - Plastic construction may not match durability of simpler steel tools - "Adjustable angle" mechanisms on budget tools can be imprecise
KITCHELLENCE 4-in-1 Knife Sharpener with Cut-Resistant Glove
The KITCHELLENCE at $17.99 is a 3-stage sharpening system that includes a cut-resistant glove, making it a particularly good starter kit.
Three standout features: - 3-stage system: diamond rod for repair, V-slot for sharpening, ceramic slot for polishing - Cut-resistant glove included for safety during use - Non-slip base for stability on counter surfaces
The included cut-resistant glove is practical for beginning sharpeners who haven't developed the muscle memory for safe tool handling. The non-slip base keeps the unit stable while pulling knives through with one hand. The 3-stage progression from diamond repair to V-slot sharpening to ceramic polish covers the full maintenance spectrum.
At 38,154 reviews and 4.5 stars, this is one of the most popular manual knife sharpeners on Amazon. The slight rating drop from the AccuSharp's 4.7 reflects different expectations. The KITCHELLENCE handles a wider range of sharpening tasks but requires slightly more technique and takes longer per session.
The limitation is scissor sharpening. The KITCHELLENCE doesn't include a dedicated scissor slot. For knife-only maintenance with safety emphasis, it's excellent. For buyers who specifically need scissors coverage, pair this with the AccuSharp ShearSharp or look at the Longzon 5-in-1 instead. You can find the kitchen knife set guide for maintenance recommendations specific to complete knife sets.
Pros: - 38,154 reviews make this the most-reviewed option in this guide - Cut-resistant glove included for safety - 3-stage system covers repair, sharpening, and polishing - Non-slip base for stable operation
Cons: - No scissor sharpening capability - 4.5 stars slightly below top competitors - Takes longer per session than the single-stage AccuSharp
Longzon 5-in-1 Knife Sharpener for Serrated Knives and Scissors
The Longzon 5-in-1 at $19.99 specifically calls out serrated knives and scissors in its name, making it the most complete multi-purpose manual sharpener for mixed knife collections.
Three standout features: - 5 slots: straightening, sharpening, polishing, saw blades, and scissors - Cut-resistant glove included for safe operation - Compact, non-slip base design for counter or drawer storage
Five distinct slots address five different sharpening needs in one unit. The saw blade slot handles serrated knives specifically, which most manual sharpeners struggle with. The dedicated scissors slot uses the correct single-face geometry for scissor sharpening. The three standard knife slots handle repair, sharpening, and polishing in sequence.
At $19.99 with 3,462 reviews at 4.5 stars, this is the best all-in-one manual solution for buyers who want knife and scissor coverage in one compact unit. The included glove mirrors the KITCHELLENCE's safety emphasis.
The 4.5 star rating with 3,000+ reviews is strong but suggests some buyer dissatisfaction. Reading the reviews, the common complaints relate to scissor sharpening performance (it works, but requires more technique than knife sharpening) and the learning curve for serrated knife slots. These are real limitations. If your primary need is scissors, the AccuSharp ShearSharp is a better dedicated tool. If you want one unit that covers everything adequately, the Longzon delivers. The nice knife set maintenance guide covers how to integrate a multi-purpose sharpener into a regular maintenance routine.
Pros: - 5 dedicated slots for different sharpening tasks - Dedicated scissor and saw blade slots - Under $20 for the most versatile manual option - Cut-resistant glove included
Cons: - Scissor slot requires more technique than knife slots - 4.5 stars suggests some performance limitations vs. Simpler tools - "5 functions" means each individual function may be less optimized
Chef's Choice AngleSelect Professional Electric Knife Sharpener
The Chef's Choice AngleSelect at $199.99 allows you to choose between 15-degree and 20-degree edges on the same machine, making it the most flexible electric sharpener for mixed knife collections.
Three standout features: - AngleSelect: applies either 15-degree or 20-degree edge on demand - Dizor technology creates a longer-lasting arch-shaped edge with two distinct facets - Precision angle guides for accurate, consistent sharpening throughout the entire edge
The dual-angle capability is the standout feature. The Chef'sChoice 15XV (reviewed above) converts everything to 15 degrees. This AngleSelect model lets you maintain each knife at its original angle or convert selectively. Japanese knives stay at 15 degrees. German knives stay at 20 degrees. Or you convert specific knives while keeping others.
The Dizor-engineered edge is a two-facet design set at different angles, creating an arch shape that's described as longer-lasting than a simple single-angle grind. The precision angle guides work on the same spring-loaded principle as the 15XV to automatically position the knife at the correct angle.
At $199.99 with 1,488 reviews at 4.6 stars, this is validated but represents a specialized need. Most home cooks don't need dual-angle capability. If you have a Japanese knife collection and a German collection and want to maintain both properly, this justifies the premium. Otherwise, the 15XV at $143 handles most needs at a lower price.
Pros: - Dual-angle capability for 15-degree and 20-degree edges - Dizor technology for longer-lasting edge geometry - Diamond abrasives throughout - Most flexible electric sharpener for mixed knife collections
Cons: - $199.99 is a significant premium over the 15XV - Does not sharpen scissors - Dual-angle feature is overkill for single-style knife collections
Buying Guide: What to Look for in a Knife and Scissor Sharpener
Dedicated tools vs. Multi-function units. The AccuSharp + ShearSharp combo uses two dedicated tools, each optimized for its task. Multi-function units like the Longzon 5-in-1 handle both tasks in one, at a slight compromise in optimization. If you sharpen knives frequently and scissors occasionally, dedicated tools make more sense. If you sharpen both infrequently, a multi-function unit is more practical.
Manual vs. Electric. Manual sharpeners are cheaper, more portable, and provide more tactile feedback about what's happening to the edge. Electric sharpeners are faster, more consistent, and require less technique. For casual home maintenance, manual is fine. For frequent sharpening of many knives, electric is worth the investment.
Abrasive material. Diamond is the most durable and effective abrasive, maintaining consistent cutting ability over thousands of cycles. Tungsten carbide is fast and effective but wears faster than diamond. Ceramic is gentle, used for fine finishing rather than heavy material removal. Better sharpeners stage these materials from aggressive to fine.
Scissor sharpening geometry. Scissors need single-face sharpening. Each blade has one flat face and one beveled face. Only the beveled face gets sharpened. Multi-function sharpeners that handle scissors need a slot designed for this geometry, not just a knife slot repurposed for scissors. The ShearSharp and Longzon 5-in-1 are designed correctly for scissors.
Safety features. Cut-resistant gloves are included with some sharpeners (KITCHELLENCE, Longzon). Non-slip bases prevent the unit from sliding during use. Finger guards on pull-through sharpeners keep your hand away from the abrasive. These aren't just marketing points. Sharpener accidents are common and preventable.
FAQ
Can I sharpen kitchen scissors the same way I sharpen knives? No. Scissors require single-face sharpening only on the beveled face of each blade. Sharpening the flat face or using a standard V-slot knife sharpener on scissors will not produce correct results. The ShearSharp tool, the Longzon 5-in-1's scissor slot, and the AGRILIA's scissor slot are all designed for the correct single-face geometry.
How do I know if my scissors need sharpening vs. Replacement? Scissors that used to cut cleanly but now push fabric or paper aside rather than cutting it need sharpening. Scissors where the blades cross rather than slide past each other need adjustment (not sharpening). Scissors where the metal is visibly nicked, chipped, or damaged may need professional service or replacement.
What angle should I sharpen kitchen scissors at? Most household scissors are beveled at 45-55 degrees on the cutting face. This is steeper than knife edges because scissors require more structural strength to withstand the lateral pressure of closing. The ShearSharp and purpose-built scissor tools are pre-set to this angle.
How often should I sharpen kitchen scissors? Kitchen shears used for cutting packaging, herbs, and small poultry pieces need sharpening about once a year with regular use. Scissors used for paper or fabric dull faster. Scissors that are never used for hard materials may not need sharpening for several years.
Are electric sharpeners bad for knife edges? Electric sharpeners remove more metal per session than whetstones or manual honing rods. Over years of frequent use, this can shorten a knife's lifespan. For a $15 kitchen knife, this doesn't matter much. For a $200 Japanese knife, a whetstone that removes less metal is the better long-term choice.
Should I buy a dedicated scissor sharpener or a combo unit? If you own several pairs of scissors and sharpen frequently, the dedicated ShearSharp is better. It's optimized specifically for scissors. If you want one unit for everything and sharpen scissors rarely, the Longzon 5-in-1 is more practical.
Conclusion
For most buyers, the AccuSharp + ShearSharp combo at $19.99 is the practical answer. Two optimized tools, strong track record, and total coverage of knives and scissors at a price that feels completely reasonable.
If you want everything in one unit, the Longzon 5-in-1 at $19.99 delivers broad coverage with its 5 dedicated slots at the same price.
For electric performance on knives and tools, the Work Sharp MK2 at $89.95 is the clear recommendation with flexible belt sharpening and proven longevity.
For the most professional electric knife sharpening with the option to maintain both 15-degree and 20-degree edges, the Chef'sChoice AngleSelect at $199.99 is the definitive option if you have a mixed knife collection.
The AccuSharp + ShearSharp combo is what I'd buy first if I were starting from scratch.
