Best Overall: Brod and Taylor Professional Knife Sharpener
A nearly foolproof manual sharpener that looks like modern art, the angle that the knife is inserted into the sharpener determines how aggressive the sharpening is (yes, there is a correct angle for sharpening your knives). You can start by sharpening the knife then hone it to a fine finish in the same slot. If the knife doesn’t need sharpening, you can use this for honing only. This sharpener self-adjusts, and sharpens the knife edge to its original angle, so you don’t need to know the edge angle to sharpen the knife correctly, and there’s nothing to adjust. The tungsten carbide sharpeners will last a long time, but can be replaced when necessary.

Best Electric: Presto Professional Electric Knife Sharpener
This sharpener can be used on metal knives of any thickness, from thin filet knives to thicker chef’s knives and cleavers. The interchangeable blade guides hold the blades at your choice of three different sharpening angles, and a slider lets you choose thick, medium, or thin blades.
The sharpener creates a slight micro-serration on the edge of the blade that results in a super-sharp edge. It might take a short while to get the technique of pulling knives through the sharpener perfected, but then it’s simple to use. This cannot be used to sharpen ceramic knives.

Best Stone: Lansky Deluxe 5-Stone Sharpening System
This sharpener includes five different sharpening stones along with a knife clamp that holds the knife during sharpening, and a guide that allows you to select the proper blade angle. Honing oil is also included. The stones have finger grips for a secure hold and are color coded so you know which are coarser and which are finer. Unlike traditional whetstones, with this system the knife remains still while you move the stones along the blade. This manual system allows you to sharpen knives at four different angles, but requires some practice to become comfortable with the technique.Continue to 5 of 10 below.

Best Budget: Smith’s Pocket Sharpener
This pocket-sized tool sharpens knives using carbide sharpening blades, then gives the knife a smooth finish using ceramic blades. A diamond rod is used for honing knives or for sharpening serrated knives. This is a great tool to keep in the toolkit, the tackle box, or to carry along when camping. Since it’s small, your hands will be close to your sharp knife blades as you work, so you might want to save it for occasional use rather than for sharpening all of your kitchen knives on a regular basis.

Best for Ceramic Knives: Gelindo 3 Stage Knife Sharpener
Since ceramic blades are so hard, not all knife sharpeners are capable of sharpening them. In fact, many knife sharpeners designed for steel knives use ceramic cutters. For ceramic knives, diamond-embedded cutters are required.
This knife sharpener has three sharpening slots with three different cutting materials: tungsten carbide, ceramic, and diamond. The diamond slot is used for ceramic knives, while the other two slots for sharpening and honing steel knives. This can also sharpen serrated knives. This sharpener is easy to use and has a handle that keeps your hand safely away from the knife blade.

Best Whetstone: Smiths SK2 Deluxe Knife Sharpening Kit
If you want to start hand-sharpening knives, and you’ve never used stones, this kit has everything you need. It includes a medium-grit stone for sharpening and an Arkansas stone for finishing. It also includes a honing solution that protects and cleans the stone’s surface as well as a small plastic guide to help sharpening novices learn the correct angle for sharpening. This is the classic method for sharpening knives, which takes some time to master, but once you learn how to use a stone, you can sharpen knives to any angle you prefer.

Best Sharpening Steel: Wusthoff Sharpening Steel
Technically, a sharpening steel doesn’t sharpen a knife, it actually hones or straightens the fine edge that gets bent during use, which makes the knife seem dull. That bending isn’t visible to the naked eye, but it still effects the way the knife cuts.
This steel has an easy-to-hold handle and loop for hanging, or it might fit in your knife block. This steel is magnetic, so it collects any metal dust created during the process. Knives should be honed regularly, so a steel is an important tool to have in your kitchen. This steel is also available in shorter and longer lengths.Continue to 9 of 10 below.

The sharpener has three slots that perform different sharpening steps from pre-sharpening to sharpening to the final honing, for a perfect edge every time.

Best for Scissors: Victorinox Swiss Army Manual Sharpener
Scissors get dull, too, but many sharpeners can’t handle their unique shape. This easy-to-use manual sharpener can handle scissor easily, and will also sharpen all of your non-serrated knives with ease. It’s ergonomically designed for either right- or left-hand use and has a protective finger guard so you can safely sharpen all the knives in the block.
The v-shaped tungsten carbide plates are placed at the perfect angle for a razor-sharp edge every time. The plates can be turned to prolong the life of the sharpener. The sharpener is dishwasher safe if it needs cleaning.

How We Tested
We bought two top-rated knife sharpeners that our reviewers tested for four hours. We asked our testers to consider the most important features when using these knife sharpeners, from their edge angle to their footprint. We’ve outlined the key takeaways here so that you, too, know what to look for when shopping.
What to Look for in a Knife Sharpener
Manual vs. electric Electric knife sharpeners are certainly easy to use, but if you don’t monitor what you're doing carefully, you may end up removing more metal than you need to. Manual sharpeners, on the other hand, can require some skill, but you’re less likely to thin out the blade too much.
Edge angle Most of the knives in your block are sharpened to a 20-degree angle. However, if you own any Japanese knives, they may be sharpened to a 17-degree angle. If you want to keep that 17-degree angle — or if you have specialty knives with other custom angles — look for a sharpener that can maintain those.
Specialty sharpening You’re likely buying a knife sharpener for your kitchen knives, but some models can also handle ceramic knives, scissors, cleavers, and other tools. Some sharpeners are only great for knives with long blades, while others are just as good at sharpening short ones. What’s in your kitchen drawer?

What We Like
What We Don't Like
“I definitely do feel a difference between when I use this knife sharpener and when I don't,” reported one of our testers. “Vegetables are much easier to chop and bread is easier to cut.” She also thought the instructions were detailed and clear, and that the sharpener looked “elegant” on the countertop. However, one of our testers did point out that because the sharpener is both large and heavy, it’s not very portable. “I would like it to be smaller and lighter — maybe one day they'll make a mini version for camping,” she mused.

Can’t sharpen scissors
Not great for extreme sharpness
If you’re looking for a basic knife sharpener at a decent price point, our testers recommended this model from PriorityChef. Our reviewers particularly liked its small size and the fact that it was easy to use. However, one of our testers cautioned, “For cooks with more delicate knives or those who desire extreme sharpness, it might be disappointing.” One of our reviewers also wished it could sharpen scissors. Bottom line: “For the casual cook with simpler knives, it's a fairly effective sharpener at a good price point,” one of our testers reported.
