If you've purchased one of the best kitchen knife sets out there, you'll want to protect your investment by giving the knives the care they need. High-quality knives aren't exactly a cheap purchase, after all, and you don't want to find yourself needing to buy a new set earlier than necessary.

Sharpening a knife is important for more than just making it easier to use, as it can also help the tool last longer. Plus, trying to cut with a dull knife can actually be a safety hazard; it's more likely to slip, increasing the chances you'll accidentally cut yourself in the process.

We considered several different aspects when assembling this collection, including the number of sharpening stages and price. We also closely analyzed customer reviews, and only chose products that had a high rating (at least 4 stars), plus feedback from at least 100 customers. To learn more about these devices, keep reading, and discover the best electric knife sharpener for your needs.

If you're looking for a knife sharpener that'll deliver comparable results to what you'd get if you had the tools professionally sharpened, you might want to consider this model from Chef's Choice. While other sharpeners only use a two-stage system, this one adds a third stage to deliver a knife that's really ready to perform.

The first two stages sharpen and hone the knife (using real diamond abrasives), while the third stage helps ensure it's beautifully polished. The third stage also makes this product a good choice for your serrated blades, which won't be compatible with many other electric sharpeners. Plus, it only takes about a minute of your time to turn a dull knife into one with an optimal, 15-degree edge that's sharp and ready to use.

A majority of customers have been impressed by this knife sharpener, with many praising it for delivering professional results. The speed in which it delivers these impressive results is another feature reviewers have highlighted in their write-ups. And while some customers stated they found minor scratch marks along the sides of some of their knives after sharpening them, most reviewers were happy with the results.

Wüsthof is one of the best knife brands, so it should come as no surprise that the company makes one of the best electric knife sharpeners, too. The brand's easy edge Sharpener features a compact and unique design. While many other models feature multiple slots for each stage they offer, this one only has two slots (one for each side of the knife). However, it still offers a three-stage sharpening design.

The secret is the touch controls. These make it possible to switch between each stage, whether you need to reshape a very dull or damaged knife, sharpen a knife, or refine the blade (it's recommended to complete this step weekly). Most customers speak highly of the brand's electric knife sharpener, with several highlighting its size as a top-selling point over other sharpeners.

Reviews also note this is very compact, so it doesn't take up a lot of space in a cabinet or on the countertops, either. The design of the tool is easy to use, as well, according to many customers, and the ability to simply press the right button to switch between the different stages has been mentioned by customers, too. Some reviewers note there's a bit of a learning curve with holding the knives correctly and pulling them through the slots, though, so it may take some time to operate it properly.

The Presto EverSharp Electric Knife Sharpener is a two-stage model that's compatible with straight-edge blades (so no serrated knives). The first stage sharpens each knife using a sapphirite sharpening wheel. As the wheel grinds the edge of the knife, it angles it to improve its cutting performance. The next stage is designed to hone the knife, ensuring it's properly aligned and ready for use.

Using this brand's electric sharpener simply involves sliding a knife through each slot a few times. After that, it should be sharp and ready to use, which is why reviewers appear glad they gave this sharpener a try. They find it helps restore the dull blades of their old knives, giving them a nice and sharp edge.

Many customers are also impressed with how quickly the electric tool works, especially when compared to trying to sharpen by hand. While some users have stated they'd like to see the motor improved so it's stronger (and doesn't accidentally shut off if the knife is pressed too firmly against the grinding wheels), you're likely to be pleased with this brand's appliance.
