The 5 Best Knife Sharpeners of 2024

Whether you’re an outdoors adventurer or in the kitchen doing hours of meal prep, finding the best knife sharpener for you fully depends on how you use your blade. Anyone who has spent serious time in a kitchen, either at home or professionally, will tell you the same thing: a dull knife is much more dangerous than a sharp knife. Sharp knives are easier to cut with, more precise, and easier to control than dull ones. In a professional setting, where time is money and presentation matters, sharp knives let chefs work more efficiently. A sharp knife in your cookware set cuts faster and leaves delicate ingredients like herbs and vegetables looking much cleaner than a dull knife would.

About Work Sharp Guided Field Sharpener

The Work Sharp Guided Field Sharpener is a really versatile piece of outdoor equipment that could serve double duty in your kitchen if you’re okay with everything having a 20-degree angle.

This one little gadget can take you through five different levels of sharpening, starting with a 220-grit surface and ending with the included leather strop. There are angle guides at every step of the process, a groove for sharpening fish hooks, and, if you remove the strop, it even turns into a broadhead wrench, letting you work on three- and four-bladed arrowheads.

What to Consider When Choosing a Knife Sharpener

Style

There are almost as many types of knife sharpeners as there are types of knives and people who use them. Something like the Work Sharp Guided Field Sharpener wouldn’t cut it in a professional kitchen, much like the Chef’s Choice 1520 wouldn’t be a sharp choice if you need to sharpen something like an arrowhead or a fishhook. Pull-through, electric, rolling, and manual sharpeners all have advantages and disadvantages — the trick is figuring out which is best for your needs. 

Ease of Use

A tool that you don’t know how to use properly is useless. Unless you’d rather your knife sharpener spend its days as a paperweight, it behooves you, as the person using and operating the tool, to choose one you know how to use or to learn how to use what you choose. Different styles of knife sharpeners all come with their own learning curves, too. 

Price

Would you buy a Ferrari if you couldn’t afford to put gas in it? Me neither. Know what knife sharpener is best for your needs — if you sharpen your knives once or twice a year, you likely don’t need the latest and greatest in knife sharpening technology (but it never hurts). Similarly, a professional kitchen might find it suitable to invest in a top-of-the-line model, since it would be seeing more regular use.

FAQ

What Is the Best Knife Sharpener You Can Buy?

The best knife sharpener depends on your needs. The best option for the kitchen that we recommend is the Spyderco Tri-Angle Sharpmaker. If you’re looking for the best electric knife sharpener or best pocket knife sharpener, you might consider the Chef’s Choice 1520 Professional Electric Knife Sharpener or the Work Sharp Guided Field Sharpener. 

What Is the Best Thing To Sharpen a Knife With?

Whetstones, also known as sharpening stones, are the best way to sharpen a knife. They limit the amount of metal you can remove from the blade with each pass — something that modern electric knife sharpeners can’t match. They are a much more labor-intensive method of keeping a blade sharp, though. 

What Do Professionals Use To Sharpen Their Knives?

Because they limit the amount of metal you can remove with a single pass, most professionals agree that whetstones are the best way to sharpen their knives. Removing as little metal as possible means you can preserve the integrity of the blade for a longer period of time, which is really important when you spend a lot of money on a nice knife. 

How Often Should I Sharpen My Knives?

The frequency with which you sharpen your own knives will depend on a few factors: the quality of your knives, how often you use them, how you use them, and more. As long as you’re not a professional chef or otherwise using your knives from dawn til dusk, you should only need to sharpen them two or three times per year. A good rule of thumb is to sharpen them whenever you can tell they’re getting dull.
