However even a premium chef’s knife will boring over time, and $150 (not to mention far costlier choices) can really feel like a waste when your Wusthof cuts in addition to a $10 generic knife after solely a month or two. Enter the knife sharpener.

The most effective sharpener I used whereas testing was the $125 Chef’s Selection Trizor XV, a cumbersome machine with three separate tracks for bringing boring 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 preserve your blade angled accurately, so danger of creating errors whereas sharpening a boring 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 machine meant I may slice via 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 value ($125 is greater than most individuals pay for a chef’s knife, not to mention the tool that sharpens it) and its cumbersome profile. However if in case you have loads of counter house or do not thoughts storing it in a cupboard, the Trizor is the best-performing machine round.

For those who’re much less keen on sustaining an ideal edge in your knife blade, and as an alternative need an reasonably priced, “good-enough” different, the $6 KitchenIQ 2 Stage Knife Sharpener may be for you. No, it will not totally resurrect an outdated, boring blade, however this sharpener will help sustain a greater edge than traditional with just some passes via the sharpening tracks every day.

The KitchenIQ additionally contains two tracks: a rough sharpener for setting the sting, and a tremendous 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 KitchenIQ stands out. 


To check our knife sharpeners, we acquired eight equivalent chef’s knives and dulled them utilizing a Dremel. They nonetheless may minimize tomatoes and pineapples (our two testing fruits), however not cleanly; primarily, we wished 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 wished them to, paired every with a sharpener and labeled accordingly. I then adopted the instructions for every sharpener. Some sharpeners prompt passing the blade via “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 minimize with every fruit out of 10, noting my particular observations. The first targets right here have been to see how sharp the sting turned 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 a better stress context — slicing via a sturdy fruit in a non-straight sample.

Which is one of the best knife sharpener for you?

A very powerful aspect of a knife sharpener is its potential to sharpen an edge throughout the size of a blade. That stated, loads of different elements would possibly make different gadgets a greater match for you. Listed below are a few of these elements:

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

Usually, sharpening a serrated blade particularly requires a serrated knife sharpener, however you continue to might need to sharpen straight paring knives, boning knives, a fillet knife, cleavers or utility blades (or perhaps a pocket knife or searching knife). Whereas the Chef’s Selection sharpener is one of the best for chef’s knives, each the Presto Three Stage and Work Sharp gadgets supply just a little extra flexibility for various blades. Presto, for example, can modify 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 method that will postpone informal cooks, however will doubtless attraction to DIY lovers.


Regardless of honest outcomes, the Work Sharp appears to be like far more at residence in a storage than on a kitchen counter.

One other consideration is how clear your sharpener is: if you happen to’re sharpening in your storage, then you definately may not 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 Selection 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 gadgets are considerably louder than others. The Chef’s Selection Trizor is barely quieter than the Presto sharpeners, however none have been silent. If you would like a quiet choice, non-electric sharpeners might be your greatest guess.

Out of all of the testing, the one machine that appeared to don’t have any upside was the $eight Kadell three Phases Sharpener, which wasn’t as reasonably priced because the KitchenIQ sharpener and in addition 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 means, meals prep will get a lot simpler once you do.
