The Work Sharp MK2 is a flexible belt sharpener for kitchen knives and a range of other edge tools. Its two-speed motor and knife edge guide suit people who want one machine for more than kitchen cutlery, while a kitchen-only sharpener may be simpler for everyday touch-ups.
This review compares the MK2 with two Work Sharp alternatives and a guided Chef'sChoice model. We compared their stated features and buyer feedback to match each one with a likely sharpening routine.
What does the Work Sharp MK2 offer?
The Work Sharp MK2 combines flexible abrasive belts, two speeds and a knife edge guide. Work Sharp says the belts conform to blade edges and can sharpen kitchen and pocket knives, serrated knives, scissors, axes and garden tools.
Work Sharp MK2 Electric Sharpener: Best for mixed kitchen and tool sharpening
- Flexible abrasive belts
- Two-speed motor
- Knife edge guide
- Sharpens knives, scissors and outdoor tools
A belt system for someone who wants to sharpen kitchen knives alongside pocket knives, scissors and garden tools. The edge guide supports the knife toward the tip, while two speeds give you more control over heavier grinding tasks.
Pros
- Works with kitchen knives and other edge tools
- Flexible belts conform to blade edges
- Two speed settings
- Edge guide supports the knife to the tip
- Work Sharp provides a 3-year warranty
Cons
- A belt system takes care and practice to use well
- Broader tool range may be unnecessary for kitchen-only sharpening
The edge guide supports a knife toward the tip, which can help make the guided knife pass easier to manage. The two speed settings offer more control for heavier sharpening or grinding tasks.
Work Sharp provides a 3-year warranty. Its range of supported tools is useful if you want to sharpen more than kitchen knives, but the MK2 may be more machine than you need for occasional kitchen touch-ups.
Who is the Work Sharp MK2 best for?
The MK2 fits a home cook who also sharpens pocket knives, scissors or garden tools. One belt system can handle several common edge tools, so it may replace separate sharpeners for different jobs.
Consider a kitchen-focused model if you want guided slots and don't expect to sharpen tools. The best pull-through knife sharpeners compares simpler options for that routine.
How does the MK2 compare with other electric sharpeners?
The main difference is how much control and range you want. The MK2 has flexible belts and two speeds, while the E2 uses kitchen knife slots, the Ken Onion Mk2 adds adjustable angle and variable speed, and the Chef'sChoice 15XV has a guided three-stage system.
| Sharpener | Score | Best fit | Notable features |
|---|---|---|---|
| Chef'sChoice 15XV | 9.2 | Guided 15° household knife edge | Three stages, diamond abrasives, precision angle guides |
| Work Sharp MK2 | 9 | Kitchen knives and other tools | Flexible belts, two speeds, knife edge guide |
| Work Sharp Ken Onion Mk2 | 8.3 | Adjustable belt sharpening | 15° to 30° angle, variable speed |
| Work Sharp E2 | 8 | Common kitchen knives | Guided slots, 1-minute timed cycle |

Work Sharp E2 Electric Sharpener: Best for a kitchen-only routine
- Guided slots
- 1-minute timed cycle

Our score weighs specs, features and buyer feedback against what you're shopping for.
Is a belt sharpener right for your knife routine?
A belt sharpener makes sense when you want powered sharpening across several kinds of edge tools. The MK2's flexible belts can work along different blade shapes, and its edge guide supports kitchen knives through the pass.
Belt sharpening takes care and practice. Follow Work Sharp's instructions and pay attention to how the belt meets the edge, since powered sharpening removes material.
If you would rather sharpen by hand, a whetstone gives you direct control over the angle and pace. Our guide to sharpening a chef's knife at home walks through the basic approach.
For a simpler guided option, the Work Sharp E2 has slots for common kitchen knives. Use that style when ease and a kitchen-only focus matter more than sharpening garden tools or pocket knives.
What should you know about sharpening angles?
An edge angle affects the shape of a knife's bevel, so match the sharpener to the edge and use you want. The MK2 has an edge guide, while the Ken Onion Mk2 adds an adjustable angle from 15° to 30°.
The Chef'sChoice 15XV is designed to convert traditional 20° household knife edges to its 15° Trizor XV edge. That may suit cooks who want a finer edge, but the best angle depends on the knife and how you use it.
Don't assume every knife should share one angle. Check the knife maker's guidance when available, especially for specialty blades or knives with a specific factory edge.
Our whetstone grit chart explains how abrasive coarseness relates to sharpening work. Grit and edge angle describe different parts of the process, so one doesn't replace the other.
Is the Work Sharp MK2 easy to maintain?
The MK2 uses abrasive belts that you can change as needed. Follow Work Sharp's care and belt replacement instructions to keep the sharpener in good condition.
Store it where the belt and edge guide won't collect kitchen debris or get knocked out of place. Unplug it and follow the manual before changing a belt or cleaning around the sharpening area.
A worn or damaged belt can affect the sharpening pass. Use the belt type and replacement method recommended for the MK2, and don't try to sharpen with a belt that is torn or loose.
What are the main reasons to choose or skip the MK2?
Choose the MK2 if you want one powered system for kitchen knives and other edge tools. Its flexible belts, two speeds and knife edge guide make it a fit for a mixed sharpening routine.
Skip it if your only goal is quick kitchen touch-ups and you prefer guided slots. The E2 focuses on kitchen knives, while the Chef'sChoice 15XV offers a guided choice for a 15° household edge.
The MK2 also calls for care when sharpening. If you want the belt system's range, take time to follow the instructions and learn the pass before working on a favorite knife.
Should you buy the Work Sharp MK2?
Buy the Work Sharp MK2 if you want belt sharpening for kitchen knives plus tools such as scissors and garden tools. Pick the Chef'sChoice 15XV for a guided three-stage 15° edge, the MK2 for a mixed kitchen and tool routine, the Ken Onion Mk2 for adjustable angle and speed, or the E2 for guided kitchen-only sharpening.

The Work Sharp MK2 can sharpen kitchen knives, and its edge guide supports the blade toward the tip. Its flexible belts also cover pocket knives, scissors and outdoor tools, so it fits a broader routine than a kitchen-only sharpener.
If you only sharpen kitchen knives, a guided countertop model may be simpler.
What is the difference between the Work Sharp MK2 and E2?
The MK2 uses flexible abrasive belts and has two speed settings for knives and other edge tools. The E2 uses guided slots for common kitchen knives, including serrated blades, and has a 1-minute timed cycle.
Pick the MK2 for broader tool use and the E2 for a kitchen-focused routine.
Can the Work Sharp MK2 sharpen serrated knives?
Yes, the MK2's flexible belts can sharpen serrated knives. Work carefully and follow Work Sharp's instructions for the belt and blade, since serrations need a different approach from a straight edge.
For routine kitchen use, the guided E2 also supports serrated knives.
Should I choose the MK2 or a whetstone?
