Chef'sChoice Trizor XV Model 15
Owners overwhelmingly love how sharp and quickly the Trizor XV gets their knives, often calling the results sharper than a professional and praising how simple and nearly foolproof it is to use. The main trade-offs are the high price and that it grinds edges down to a narrower 15-degree angle, which removes metal and isn't to every cook's taste.

Work Sharp Folding Field Sharpener
Owners are enthusiastic about the Work Sharp Folding Field Sharpener, praising its compact form factor as ideal for camping and portable knife maintenance. One owner found the 20 degree guides matched their knives exactly, and the flat ceramic surface gets called effective on shorter blades of around four inches. The main tempered note is that it can be hard to judge results with ceramic, but overall owners consider it a solid, well-designed field tool.

Work Sharp Ken Onion Edition
Owners consistently call this one of the fastest ways to get a knife razor sharp, taking a dull or even damaged blade to a shaving edge in just a few minutes with little skill required. The belt system puts on a durable convex edge and handles everything from kitchen knives to axes. The trade-off is that it removes metal aggressively and can overheat, scratch, or round tips, so most owners stress using slow speeds and practicing before trusting it on a favorite blade.

Work Sharp MK2
Most owners of the Work Sharp Mk2 rave about the results, describing shaving- and razor-sharp edges on pocket knives, kitchen knives, and hunting blades that come out sharper and faster than hand-stone sharpening, sometimes in just a few minutes. Many praise how approachable it is for beginners, getting solid results with little training, and find it ideal for quick touch-ups on beater or hard-use knives. A meaningful minority, however, describe a real learning curve: several owners admit to nicking, unevenly grinding, or rounding the tips of blades while figuring the tool out, and a few now limit it to cheap kitchen knives after damaging ones they cared about. Overall the consensus is that it's a fast, effective sharpener that rewards a careful, go-slow approach while you learn it.

Lansky Deluxe 5-Stone System
The Lansky Deluxe 5-Stone is an affordable, beginner-friendly kit whose angle guides help newcomers hold a bevel, and patient owners get shave-sharp results that can last for years and rescue badly damaged edges. But it's a mixed bag: many call the clamp squishy and loose, the setup slow and finicky, and matching the angle tough on a lot of knives. Several hit harder problems too, including brackets that bend or snap, stones striking the clamp on small blades, and weak performance on super steels.

Every knife sharpener in this ranking, by what owners actually say

Owners' top-rated knife sharpener is the Chef'sChoice Trizor XV Model 15 — 94% of 18 owners recommend it. Updated July 2026.

Five picks here split along one line: how much of the work the machine does, and how much steel it eats doing it. The Chef'sChoice Trizor XV Model 15 is the kitchen electric, fast and close to foolproof, though it regrinds edges to a narrower 15 degrees and costs the most. Work Sharp covers the powered belt tier twice over, with the Ken Onion Edition as the more capable machine and the MK2 as the simpler one; both put a shaving edge on a blade in minutes, and owners of both describe rounding a tip while learning. The Lansky Deluxe 5-Stone is the slow, cheap, guided-rod route, loved by patient users and cursed for its loose clamp. The Work Sharp Folding Field Sharpener is the pocket tool for trail touch-ups, and far fewer people have reported back on it.

Knife Sharpeners: frequently asked questions

Ken Onion Edition or MK2: which Work Sharp belt sharpener makes more sense?

The Ken Onion Edition has by far the deeper track record, with 78% of 111 owners recommending it against 69% of 13 owners for the Work Sharp MK2. Both do the same core job, taking a dull or even chipped blade to a shaving edge in a few minutes, and owners of both report the same hazard: a rounded tip or an unevenly ground bevel while they were still learning the tool. The Ken Onion Edition is the more versatile of the two, used on axes and garden tools as well as knives, while the MK2 gets described mostly as a quick touch-up machine for pocket, kitchen and hunting blades. The advice repeats on both: run it at slow speed and practice on knives nobody cares about, because several MK2 owners now limit it to cheap kitchen knives after damaging ones they liked.

Is the Chef'sChoice Trizor XV worth its price for kitchen knives?

It is the best-regarded pick in this category, recommended by 94% of 18 owners, and the praise is specific: results people describe as sharper than a professional service, a full knife set done in minutes, and very little to get wrong along the way. Two caveats come up often enough to weigh first. It costs more than the other options listed here, and it converts edges to a narrower 15-degree angle, which removes a fair amount of metal and leaves a bevel geometry that not every cook wants on their knives.

Does a guided rod kit like the Lansky still make sense next to a powered sharpener?

It is the most divided pick in the category, recommended by 46% of 61 owners. The case for it is real: it is cheap, the angle guides help a beginner hold a consistent bevel, patient users get shave-sharp edges that last, and it can rebevel a badly damaged knife. The case against it is just as concrete. The clamp gets called squishy and loose, setup is slow and fiddly, the stones hit the clamp on small blades, matching an existing angle is hard on many knives, and the brackets and rods bend or snap for some owners. Hard modern steels are where it struggles most.

Which of these works for sharpening away from home?

The Work Sharp Folding Field Sharpener is the only pick built for a pack, folding down small enough to live in camping gear, with a flat ceramic face that works best on shorter blades around four inches and under. Only seven owners have reported back on it, so its 86% recommend rate is an early read rather than a settled verdict, and the picture it paints is modest by design: it puts a solid working edge on a knife rather than a razor edge, and one owner found the ceramic hard to judge, saying the edge felt right but there was no clear sense of how much the stone was doing.
