6 Best Knife Sharpeners

This knife sharpener looks more like a power tool than a simple sharpener, but that’s part of what makes it so great. Its design—using a flexible motor-powered band—gives you more control over your knife sharpening. Not only will it do an amazing job with kitchen knives, but you can use it for everything from garden scissors to axes to lawnmower blades. 

The flexible abrasive belts are interchangeable, with three options (coarse, medium, and fine) to help you take control over the sharpening. The belts won’t burn the steel while you sharpen it, simply grind down the metal until you have the edge you want.

Thanks to its unique design, this sharpener will be very easy to use. It’s even built with sharpening guides that help you to sharpen standard-sized/shaped blades quickly. The angle of the sharpening can be adjusted (between 40 and 60 degrees) to ensure each knife or tool is sharpened to its ideal edge. 

For those who want more control over the sharpening, the adjustable motor speed on this device is a total win. You can speed up or slow down the motor according to how much you want to work each edge, letting you control the sharpening process.

But it’s not just intended for kitchen use! If you want to take it camping with you, you can connect it to your car or RV’s 12V plug to run it from your battery. It’ll make sharpening your knives anytime, anywhere a breeze! Whether you’re working with straight-edge knives, serrated edge knives, or gut hooks, this sharpener’s up for the job.

Just $70 for this amazing tool? Heck yeah! It’s a bit pricier than the manual sharpeners, but when you see what it can do with your knife blades, you’ll be glad you bought it.

The built-in Universal Knife Guide Slot ensures that your knife is kept at the best angle for the perfect V-shaped edge—18 degrees for the coarse setting, 20 degrees for the fine setting. Best of all, when you want to clean the sharpener, you can simply pop off the cartridge and cover for easy access.

As many professional chefs will tell you, the only way to get a proper edge on your kitchen knives is using a whetstone. With its two sides—coarse on one side, fine on the other—whetstones give you the best possible sharpening and the most control over the edge you put on your knives.

This whetstone comes with dual sides, with a coarse side for grinding down dull edges and a fine side for honing and polishing. But the stone doesn’t come on its own—it sits on a silicone base inside a bamboo base. The silicone stops the stone from sliding around and the bamboo base makes it easy for you to hold the stone safely while sharpening. The combination makes for a much more user-friendly process.

This whetstone is designed to be user-friendly, with dual edges that are durable and deliver consistent sharpening. There’s no need for fancy oils—all you need is water, your knife, and this stone. Though whetstones aren’t the fastest for sharpening, they’re the best if you want to be in full control of your sharpening process. Ultimately, you’ll get a better-quality sharpen with this whetstone.

At $40, this whetstone is just what you need to get your knives in chef-quality condition. It’s safe to use, user-friendly, and guaranteed to deliver the best possible edge if you use it right.

Have you ever watched Gordon Ramsey sharpen knives on TV? You’ll find he typically uses one of these sharpening steels for a lightning-fast sharpen. The handle is designed be comfortable to grip, and the 12-inch steel rod is long enough that you can easily run it across the full length of a chef’s knife in a single pass. It’s heavy enough that you know it’s solid, but just light enough that you can sharpen your knives without fatigue.

The sharpening steel is as simple as you’d expect: a plastic comfort-grip handle attached to a 12-inch length of steel. The sharpening edge is fine enough to put a very good edge on your knives, making this the perfect “finishing” tool to keep your kitchen knives sharp.

The rod can either be hung on a wall rack (by its built-in hanging loop) or on a magnetized knife rack (it is, after all, stainless steel).

Lightweight, very easy to use, and safe for even the sharpest knives, you’ll find this sharpening steel makes honing your knives a breeze. Thanks to the multi-edged design of the sharpening steel, you can give both edges of the knife a quick sharpen in just a few seconds.

If you want to go really cheap, this is your best choice. At just over $13, you have a tool guaranteed to keep your kitchen knives sharp, and the sharpening process is very quick and easy.

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. Simply place the knife on the counter blade-side up and, with a few passes of the AccuSharp, you’ll find yourself with a wonderfully sharp knife once more.

Thanks to the plastic finger guard, you won’t have to worry about slicing your fingers ever again. The handle is easy to hold, ergonomic, and comfortable, so you can sharpen all your kitchen knives in a single go with no discomfort.

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.

Less than $10 to revive old, dull knives? Yes please!
