Wüsthof knows knives, and they certainly know sharpeners. The Wüsthof PEtec electric model provides professional sharpening in your own home. For a larger budget, you get a quality sharpener that will last for decades while maintaining all your knives to a precise 15-degree angle.

How We Picked

Keeping a knife sharp prevents injuries and ensures you get a quality cut every time. A home knife sharpener is a perfect way to ensure all your blades stay sharp. There are many different types of sharpeners available, and for real knife enthusiasts, using a whetstone would be the only acceptable method of sharpening. However, those types of traditional sharpeners are hard to master for someone who only needs to sharpen blades a few times per year. And sharpening a knife with this method can take up to 20 minutes per blade.

For this review, we looked for sharpeners that would appeal to the average home cook who plans to use their device no more than once per month. We have included both manual and electric models that require little training or practice and can easily be used by reading some simple instructions. These all produce sharp edges that do not damage the knife or require additional honing.

By comparing product specifications, customer reviews, and the tests of industry leaders, we have come up with our recommendations for the top 10 knife sharpeners available this year. This inclusive list contains recommendations for all types of knives and needs, and every sharpener on our list will give you an excellent edge. Each has a built-in guide that will help keep your knife at the proper sharpening angle, and all include instructions for their use.

Buyer’s Guide to Finding the Best Knife Sharpener

Purpose

The knife sharpener you buy should be able to do the jobs you need it to do. If you have lots of knives with various types or lengths of blades, you should purchase a sharpener that is capable of sharpening them all. Whether you plan to use your sharpener monthly versus once a year should also be included in your criteria. Consider the length, type, current sharpness, and angle of all your current blades before choosing a sharpener.

Sharpness

The purpose of a knife sharpener is to give you the sharpest blade possible, so you want to be sure that whatever you buy is consistently giving you a sharp, even edge. If there is a steep learning curve to using the sharpener or there is a danger that you could do more harm than good to your knives, then you should consider a different sharpener.

Safety

Look for sharpeners that are designed to protect the user from slips and accidental cuts. Some products come with guards, gloves, or other protective gear, while others are designed to ensure the blade is safely away from hands.

Ease of Use

For this list, we considered all types of sharpeners, including manual whetstones and other, more professional systems. While manual sharpening using a whetstone will give you the sharpest blade, they are also time-consuming to use and, for the average home cook, they are very easy to mess up, which could damage your blades. The systems on our list are all easy to use, but some are easier than others. Select one that matches your level of comfortability and skill and consider how long it will take to sharpen each knife.

Quality Materials

Because you are purchasing a knife sharpener to extend the life of your cutting tools, you should be sure that the product you are buying is also made to last. Look for quality materials and construction that won’t break, which could cause damage to your knife or yourself while sharpening.

Angle of Edge

Depending on the type of knife you have and the material from which it is made, your knife may require a 20-degree or 15-degree edge angle. Some softer materials are not capable of holding the more acute angle while others are explicitly designed to be used for more precision cutting. If you have high-quality knives and you want to preserve the factory edge, be sure you purchase a knife sharpener that is compatible with the type of edge you require.

Frequently Asked Questions

Q: How do sharpeners work?

A: Sharpeners all work in essentially the same way. Abrasive material of some kind is passed along the edge of the blade to grind away a small amount of material to make the knife’s edge sharp again. Depending on the type of sharpener you are using, the abrasive material can be made from diamonds or other gemstones, other types of stone, steel, ceramic, or any other rough surface that is harder than the knife itself. After the edge is ground down, a material with a finer grit is usually used to polish away any burrs left from the grinding.

Q: Why should I sharpen my knives?

A: There are many reasons why you should maintain a sharp edge on all your blades. First, a sharp edge is less likely to cause injury. When a knife is dull, it requires you to use greater force, which is more likely to cause injury should a slip occur. A sharpened knife lasts longer, too, because a finely sharpened blade has a smooth edge that resists breakage.

Q: Can knife sharpeners damage my knives?

A: If used incorrectly or aggressively, it is possible to damage your knives using just about any type of sharpener. By following the instructions provided with your sharpener and being gentle with your blades until you get the hang of your particular model, you can lessen your chances of making mistakes or causing damage.

Q: How often should I sharpen my knives?

A: The answer to this question depends on several variables. First, consider how often you use your knives. Most people who cook only a few nights per week or use their knives infrequently can sharpen every three to four months with no problems. Those who cook daily and use their cutlery frequently may want to sharpen them more often. True chefs will sharpen their blades before each use. Knives made from stronger materials will hold their blade edge longer than softer materials, too. Sharpen then as often as you need to maintain a fine edge.

Q: Will all sharpeners work for all types of blades?

A: No, not every sharpener is appropriate for sharpening straight, serrated, santoku, ceramic, and other types of knives. You should read your model’s manual to determine which types of surfaces can be sharpened. Scissors are often the most questioned type of blade, as many home sharpeners cannot handle these complex edges.

Q: Can knife sharpeners be used to sharpen garden tools?

A: A few can but not many. The edge angle of kitchen knives is very different than those of garden sheers, hedge clippers, axes, and other types of outdoor tools. If your sharpener has an adjustable angle or if it is made to accommodate various kinds of blades, then it may work for your tools. Consult your manual for specific answers to questions you have about your sharpener’s capabilities.

Q: Aren’t whetstones the best way to sharpen a blade?

A: Using a whetstone is indeed a time-honored and extremely effective method for sharpening blades. This process requires holding the knife at a very specific angle, running the knife in a particular pattern multiple times across the stone, and gradually decreasing the grit of the stone until you get the polished edge you want. Because this is a labor-intensive and sometimes hard-to-master process, the average home cook looks for a more guided type of sharpener that lessens the chances of damaging the blade.
