Best Electric Knife Sharpener Guide 2020

When you decide that you need to add a knife sharpener to your collection of gear – whether for kitchen knives or other knives – you will have to pick between a manual model and an electric one. There isn’t necessarily a right or wrong answer in this case, as both can get the job done nicely. Your best bet is likely to browse both manual and electric options before making a purchase so you can weigh the pros and cons on both sides.

kitchen knives or other knivesObviously, in this article, we are going to focus exclusively on the electric half of the equation. One of the main advantages of an electric knife sharpener is speed. These models are going to sharpen your blade faster than a manual model, as you have power on your side. Of course, along with that speed usually comes a larger price tag and more things that can go wrong with the unit. However, if you want to get the job done right and get it done fast so you can get started using the knife, there is a lot to like about an electric sharpener.

The leading frustration with an electric knife sharpener is simply that it doesn’t do a good enough job of getting the blades sharp. This is a case of making sure the unit you purchase can do the one thing that it is supposed to be good at doing. If you are going to invest a hundred bucks or more in a sharpener, it better be up to the task of sharpening your blades properly. To make sure that you pick out a quality model, it can help to review the comments of previous buyers to see if they have been happy with their experience.

Another buying consideration to make when picking a sharpener is the types of knives that the unit will be able to sharpen. Some sharpeners, for instance, claim to be able to sharpen a serrated edge, while others do not. Also, the size of your knives is important to think about. Most sharpeners aim at functioning with a set of basic kitchen knives, but you may need something more substantial if you have large hunting blades or other similar items to sharpen.

This article is going to highlight seven of the best electric knife sharpeners that you will find for sale today.Each has its own unique set of capabilities and features. The reviews can be a big help when it comes to picking a winner for your own purposes. We hope that this list will shorten your shopping time and make it easier for you to come to a confident buying selection.

The Presto 08800 EverSharp offers a two-stage system for sharpening your blades, with one stage meant to prepare the blade and the other to finish off the task. With the preset angled slots in place to accept your blades, you won’t have to worry about holding the knives at the right angle– that task will be handled automatically for you.

2. Chefs Choice 250 Diamond Hone Hybrid Knife Sharpener

Image of Chef's Choice 250 Diamond Hone HybridThis second option on our list is more expensive than the first, and the reason is right there in the title. Using diamond abrasives in the third stage of the sharpening process, this product can achieve a beautiful and sharp finish when used correctly. The reason this model is known as a hybrid is due to the fact that the first two stages of the process are electric while the third stage is manual in operation. Unlike many of the other models on the market today, this product is capable of working on both straight and serrated blades.

Most of the reviews for this product are highly complimentary, claiming that this item can sharpen all of their kitchen knives with very little effort. Complaints are hard to find when it comes to this product, which is a good assurance that you are dealing with a quality piece of machinery. You will have to spend more to have the advantage of a diamond surface, so the choice will be up to you on the final budget that you set for this purchase.

3. Electric Diamond Knife Sharpener

Image of Electric DiamondMany of the models you will find on our list are only able to work on steel knives, so we felt it was important to include a model that offers sharpening for both steel and ceramic knives. Although ceramic knives are not as common as steel, they do exist in the market, and you may own a few yourself. If so, you will want to consider this product, which offers a two-stage diamond sharpening wheel. The diamond wheel cartridge can be removed for easy cleaning.

There are not as many reviews for this product as for many of the others on the market, but those that have been left are very positive. Comments include the sturdy design of the product, the ease with which it can be cleaned, and the ability to use the sharpener without having to mount it. One limitation of this item is that it does not sharpen serrated blades, but that is something that can be said about most of the electric sharpeners on the list (and on the market at a whole). For a sturdy item that can deal with both ceramic and steel knives, check out the Electric Diamond Knife Sharpener.

4. McGowan Firestone Electric Sharpener

Image of Mcgowan FirestoneIf reviews matter to you, it would be worth your time to check out the Firestone Electric Knife Sharpener by McGowan. This is a product that has received excellent reviews. Despite a price tag that comes in higher than many other options, this product has earned a good number of fans. It is made in the USA, it features ceramic sharpening wheels, and it makes quick work of the job at hand.
It is not easy to find complaints about this product, but there is no problem finding compliments. Users have stated that it sharpens quickly; it is easy to work with, and the unit has an overall high quality.

The only complaint that is frequently seen isn’t really a complaint so much as a warning. A few users report that this unit works so well that you have to be careful not to remove too much material from your knife. When used correctly, however, the McGowan is an impressive machine which can leave your knives sharp and ready for duty.

5. Chefs Choice 315S Diamond Electric Sharpener for Asian-Style Knives

Image of Chef's Choice 315S DiamondAs you can tell from the title of this product, it is meant for a very specific type of knife. Therefore, if you dont own an Asian-style knife, or if you only own one or two, this might not be the right sharpener for you. However, if your collection is full of Asian-style knives, you will want to review the benefits of this electric sharpener closely. It features a two-stage system to bring knives up to a sharp edge, and diamond abrasives are used in the first stage of the sharpening process.

Most of the Chefs Choice products in the knife sharpening market have received positive reviews, and this model is no different. Plenty of users have praised the work that is done by this sharpener, with compliments on its ability to create a sharp edge. This product is more-expensive than most of the electric sharpeners you will find, but that investment may be worth it to you in the end if it extends the useful life of your knife set.

6. Smiths 50005 Edge Pro Compact Electric Knife Sharpener

Image of Smith's 50005 Edge Pro CompactAs is the case with most sharpeners, it uses a two-stage process to get to a sharp edge on the blade of the knife. The coarse side of the sharpener will go to work on a dull blade to get it back into shape while the fine side will finish things up by putting the edge back in line properly.

From the limited number of reviews which have been left for this product, it appears that the majority of purchasers are happy with the job done by the 50005 Edge Pro. Most of the comments indicate that the sharpener can bring knives up to a sharp edge with relatively little effort by the user.
