A dull knife isn’t just useless—it’s actually more dangerous to work with! Not only are you more likely to make mistakes with a dull knife, but you have to work harder to cut, meaning there’s a higher chance of slipping, slicing yourself, or mangling the food you are cutting.
That’s when you need a knife sharpening system! Whether you use a ceramic knife sharpener, a whetstone, a sharpening steel, or the best electric knife sharpener around, you want to always make sure your knives are good and sharp. Sharp knives give you cleaner cuts, make less mess, and are far less likely to cause injuries.
Not sure which is the best knife sharpener for you? Below, we’ve done the hard work of compiling all the best options so you can find the absolute best-of-the-best, no matter how you like to sharpen your knives.
Good luck, and happy sharpening!

May ruin good knives with overly aggressive sharpening.
This device is designed to turn even the dullest knife into a razor-sharp tool, and you’ll find it gets the job done in a matter of SECONDS rather than minutes.

The tungsten carbide honing edge will do an amazing job of sharpening even the dullest knife, and you’ll find just a few passes of the sharpener will do the trick.
Fair warning: DO NOT use this with high-quality knives. The sharpening is far too aggressive and will ruin a good knife, so only use the AccuSharp with old or low-cost kitchen knives. You’ll find that after a year or so of use, the AccuSharp will wear the knife down so much that you’ll have to throw it away. Hence, if you have good knives, you’re better off with one of the higher-priced knife sharpening systems.
But if you’ve got a drawer full of older knives that are just gathering dust, the AccuSharp is just the tool you need. It’ll put a beautiful edge back on those knives, and you’ll get a few good years out of those older knives.
