I’ve used a lot of chef’s knives over time and are available to understand every of them for his or her distinctive really feel — the heavy-duty Wusthof (my first chef’s knife) is nice for chopping squash, whereas I like my Mac knife for mincing veggies and herbs. However even a premium chef’s knife will boring over time, and $150 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.

Knife sharpeners are far much less widespread within the common kitchen than many other tools, regardless of their worth. Some skilled cooks sharpen their knives each day, however even the informal cook dinner will profit immensely from sharpening their knives as soon as a month.

The excellent news is, knife sharpeners do not need to be big investments. Like another kitchen device, what you set in is usually what you get out: A couple of dollars can get you measurable enhancements to your blade, and 20 instances that may maintain your chef’s knife’s edge as sharp as new in perpetuity.

There are many instruments on the market for maintaining knives sharp — we’re certain you are all acquainted with the sharpening stone and the sharpening rod — however we needed the knife sharpening course of to be slightly simpler than these explicit sharpening instruments. So we examined the heck out of some sharpeners to determine which of them will all the time lead to a pointy knife with out you having to fret in regards to the sharpening angle or anything, and nonetheless get a razor sharp edge from a previously blunt knife. Listed here are our picks of the very best knife sharpener on your chef’s knife, and we will replace it as we take a look at extra merchandise.

A notice, although: We’re speaking simply chef’s knives right here. A serrated knife might have a special sort of sharpener.

One of the best sharpener I used whereas testing was the $150 Chef’s Selection Trizor XV, a cumbersome gadget 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 maintain your blade angled appropriately, so threat of constructing errors whereas sharpening a boring blade on the diamond abrasive sharpeners is fairly minimal. 

The outcomes of my testing had been spectacular. The sharp blade and clean edge produced by the gadget 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 price ($150 is greater than most individuals pay for a chef’s knife, not to mention the device that sharpens it) and its cumbersome profile. However you probably have loads of counter house or do not thoughts storing it in a cupboard, the Trizor is the best-performing gadget round.

If you happen to’re much less serious about sustaining an ideal edge in your knife blade, and as an alternative need an inexpensive, “good-enough” various, the $6 KitchenIQ 2 Stage Knife Sharpener could be for you. No, it will not absolutely resurrect an outdated, boring blade, however this sharpener will help sustain a greater edge than regular with only a few passes via the sharpening tracks every day.

The KitchenIQ additionally contains 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 KitchenIQ stands out. 


To check our knife sharpeners, we acquired eight identical 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 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 sure 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 steered passing the blade via “till sharp,” and I did so till the enhancements appeared negligible. Different sharpeners had been extra prescriptive, and I adopted the instructions exactly.

After sharpening, I examined every knife, 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 objectives right here had been to see how sharp the sting turned and the way clean it was throughout its size: a pointy blade should not squash a tomato, and a clean blade should not tear its pores and skin. A pineapple would take a look at the identical results in the next stress context — chopping via a sturdy fruit in a non-straight sample.

Which is the very best knife sharpener for you?

Crucial factor of a knife sharpener is its means to sharpen an edge throughout the size of a blade. That mentioned, loads of different elements may make different gadgets a greater match for you. Listed here are a few of these elements:

  • Capability to sharpen various kinds 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 searching knife). Whereas the Chef’s Selection sharpener is the very best for chef’s knives, each the Presto Three Stage and Work Sharp gadgets supply slightly extra flexibility for various blades. Presto, as an illustration, 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 strategy that will delay informal cooks, however will possible attraction to DIY lovers.


Regardless of truthful outcomes, the Work Sharp appears to be like way more at dwelling 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 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 Selection Trizor and the $25 AnySharp Pro sharpener had been the cleanest. That mentioned, 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 had been silent. If you need a quiet possibility, non-electric sharpeners will probably be your finest wager.

Out of all of the testing, the one gadget that appeared to don’t have any upside was the $8 Kadell 3 Stages Sharpener, which wasn’t as inexpensive because the KitchenIQ sharpener and in addition carried out worse than another sharpening device I examined. Moreover that one, it appears just about any knife sharpener is best than no knife sharpener. So spend money on the excessive finish or decide up a $6 device. Both approach, meals prep will get a lot simpler if you do.
