The most effective sharpener I used whereas testing was the $150 Chef’s Alternative Trizor XV, a cumbersome gadget with three separate tracks for bringing uninteresting knives to a super-sharp 15-degree edge (many American knives are sharpened to a 20-degree angle). The Trizor additionally comes with thorough and useful instructions to be used — explaining unfamiliar phrases and processes in easy methods. Plus, magnets on the sharpening tracks hold your blade angled accurately, so danger of constructing errors whereas sharpening a uninteresting blade on the diamond abrasive sharpeners is fairly minimal. 

The outcomes of my testing have been spectacular. The sharp blade and easy edge produced by the gadget meant I may slice by a tomato with out squashing it or tearing the pores and skin due to inconsistencies throughout the size of the sting.

The one draw back of the Trizor sharpener is its premium price ($150 is greater than most individuals pay for a chef’s knife, not to mention the tool that sharpens it) and its cumbersome profile. However you probably have loads of counter area or do not thoughts storing it in a cupboard, the Trizor is the best-performing gadget round.

Should you’re much less concerned with sustaining an ideal edge in your knife blade, and as a substitute need an reasonably priced, “good-enough” different, the $6 Kitchen IQ 2 Stage Knife Sharpener could be for you. No, it will not absolutely resurrect an outdated, uninteresting blade, however this sharpener may help sustain a greater edge than normal with just some passes by the sharpening tracks every day.

The Kitchen IQ additionally consists of two tracks: a rough sharpener for setting the sting, and a high-quality sharpener for ending it. When in comparison with different compact, non-electric merchandise, just like the $25 Anysharp Professional with solely a rough sharpener or the poorly performing $eight Kadell three Phases sharpener, the Kitchen IQ stands out. 


To check our knife sharpeners, we acquired eight an identical chef’s knives and dulled them utilizing a Dremel. They nonetheless may lower tomatoes and pineapples (our two testing fruits), however not cleanly; basically, we needed our knives to behave like chef’s knives which have seen years of use with out a lot repairs.

I examined the knives earlier than sharpening them to make certain all of them carried out about as poorly as we needed them to, paired every with a sharpener and labeled accordingly. I then adopted the instructions for every sharpener. Some sharpeners urged passing the blade by “till sharp,” and I did so till the enhancements appeared negligible. Different sharpeners have been extra prescriptive, and I adopted the instructions exactly.

After sharpening, I examined every knife, taking a look at how a lot it squashed a ripe tomato and tore its pores and skin whereas slicing, in addition to how simply it sliced pores and skin from a ripe pineapple. I rated the lower with every fruit out of 10, noting my particular observations. The first objectives right here have been to see how sharp the sting grew to become and the way easy it was throughout its size: a pointy blade should not squash a tomato, and a easy blade should not tear its pores and skin. A pineapple would check the identical results in the next stress context — reducing by a strong fruit in a non-straight sample.

Which is the very best knife sharpener for you?

An important ingredient of a knife sharpener is its capacity to sharpen an edge throughout the size of a blade. That stated, loads of different components may make different units a greater match for you. Listed here are a few of these components:

  • Capacity to sharpen several types of knives
  • Cleanliness
  • Sound

Usually, sharpening a serrated blade particularly requires a serrated knife sharpener, however you continue to could wish to sharpen straight paring knives, boning knives, a fillet knife, cleavers or utility blades (or perhaps a pocket knife or looking knife). Whereas the Chef’s Alternative sharpener is the very best for chef’s knives, each the Presto Three Stage and Work Sharp units provide somewhat extra flexibility for various blades. Presto, as an illustration, can regulate its slots to information completely different blades extra successfully. Work Sharp makes use of attachments and belts of various coarseness for kitchen knives, pocket knives or scissors — a modular strategy which will delay informal cooks, however will doubtless enchantment to DIY fans.


Regardless of truthful outcomes, the Work Sharp appears far more at house in a storage than on a kitchen counter.

One other consideration is how clear your sharpener is: in the event you’re sharpening in your storage, you then won’t sweat the metal filings that sprinkle out of some sharpeners, just like the Work Sharp or the Presto sharpeners. In a kitchen setting, cleanliness is a should, and Chef’s Alternative Trizor and the $25 AnySharp Professional sharpener have been the cleanest. That stated, all of the above suggestions required minimal cleanup, if any in any respect.

Lastly, sound is a priority for some — and a few of these units are considerably louder than others. The Chef’s Alternative Trizor is barely quieter than the Presto sharpeners, however none have been silent. In order for you a quiet possibility, non-electric sharpeners can be your greatest wager.

Out of all of the testing, the one gadget that appeared to don’t have any upside was the $eight Kadell three Phases Sharpener, which wasn’t as reasonably priced because the Kitchen IQ sharpener and likewise carried out worse than every other sharpening tool I examined. Moreover that one, it appears just about any knife sharpener is healthier than no knife sharpener. So put money into the excessive finish or choose up a $6 tool. Both manner, meals prep will get a lot simpler whenever you do.
