Best Knife Sharpeners of 2020 to Help You Hone Your Knives

A dull knife isn’t just annoying to work with – it’s also dangerous.

Cut your food with a knife that hasn’t been sharpened in a while, and you’re going to be at a higher risk of a deep, painful cut. Not only will you have to exert more force as you’re cutting your food, but you’re not going to love the results of all your hard work, either.

Knife sharpeners are simple tools that use abrasive materials to hone your blades. Not all knife sharpeners are built alike, though. While it can be overwhelming to choose from the hundreds of options out there, this isn’t a purchase that you should take lightly.

No matter how often you cook, you are going to need a knife sharpener to keep your knife sharp – remember, a dull knife is a dangerous knife, and it’s also ineffective.

Here’s what you should be looking for – along with our top recommendations.

10 Best Knife Sharpener Reviews

1. Presto 8800 08800 EverSharp Electric Knife Sharpener

    One of the best knife sharpeners you will find is this electric sharpener by Presto. An easy to use the device, it offers a two-stage sharpening approach that can hone just about any type of non-serrated blade. It produces professional results without requiring you to ever leave your home.

    In the first stage, your knives will be precisely ground to begin the process of sharpening with the creation of a perfectly angled edge. In the second stage, the knife’s edge will be refined and polished for a long-lasting finish.

    At 120 volts, it has enough power to sharpen your most difficult knives – but doesn’t draw so much power that you’ll notice a difference in your electric bill. It positions your knife at the perfect sharpening angle for guaranteed results each and every time, so there’s no guesswork required. You’ll get a razor-sharp edge in a matter of seconds – not hours.

    The knife sharpener has three separate suction cups affixed to the bottom. This help holds the sharpener securely in place on your table or countertop. There is also a storage receptacle on the bottom of the sharpener that can catch all of the discarded metal filings, instead of getting them all of your counters.

    This knife sharpener has sapphite sharpening wheels – this is the same material used by professional knife sharpening shops. Built to North American Electrical Standards, it is easy to use and the perfect choice for any home chef.

You’ll also benefit from a Soft Touch handle that will give you a secure, comfortable grip.

      The fastest manual, 15-degree knife sharpener available, this knife sharpener offers a flawless factory edge each and every time. The diamond abrasive is the strongest material known to man, yet it won’t damage your knives because the CrissCross technology ensures a perfect fit.

        It also has a bottom slot for scissors. This is a helpful feature if you have struggled to find a sharpener that works on scissors in the past – in fact, it’s worth mentioning that most knife sharpener manufacturers recommend not using their products on scissors because it can cause damage.

                      Deciding Which Product Is the Best Knife Sharpener for You

                      Finding the right knife sharpener can be a challenge, especially if you are new to sharpening knives or worse, are looking for a gift for someone else!

                      To decide which knife sharpener will work best, think first about the type of knife you are using. A western knife will be best for dealing with tough vegetables or animal products, while an Asian knife is generally used on fish and soft vegetables. The angles of these knives vary – a western knife usually contains a blade angled at 20 degrees, while an Asian knife is only angled at 13 to 15 degrees.

                      Your knees will also vary slightly depending on their blade grinds, or blade shapes. You can have knives with hollow, flat, convex, chisel, and tapered edge.

                      If you have a wide assortment of knives, you may find that a knife sharpening kit works best for you. Otherwise, learning how to work with a manual system (like a whetstone or a rod) will be best for you, as you can change your technique depending on the type of knife you are sharpening.

                      Consider our comprehensive list of the best knife sharpeners as you make your final decision. With a little bit of luck and some practice in mastering the technique of sharpening your knives, you’ll have dinner on the stove in no time.
