After a long period of being in use, knives are bound to go dull sooner or later. Of course, no one throws away a good, albeit a bit dull, knife without trying to sharpen it first. While many people prefer to use manual knife sharpeners, in this day and age, electric knife sharpeners seem to be gaining an ever-increasing popularity. Check out my review for best electric knife sharpeners to determine which product is the right one for you.
Benefits of Using Electric Knife Sharpeners
Using a dull knife is no fun, especially when it can’t do its job nearly as well as initially. In cases like this, a knife sharpener is a hero we need.
Knife sharpeners come in four vastly different types – sharpening stones, sharpening steels, manual knife sharpeners and perhaps, the most famous of all – electric knife sharpeners.
This begs the question, what makes electric knife sharpeners so popular? What makes them a go-to choice for many professionals as well as amateurs alike? Well, their reputation might be thanks to the convenience they can bring about.
Easy To Use
This is perhaps the biggest reason why electric knife sharpeners win over so many people. Unlike manual knife sharpeners that require skills and careful handling, electric ones require little to no skill to operate them. As long as you know how to determine when a knife needs a proper sharpening, all you need to do is to stick it in an electric knife sharpener and wait for the result.
Does Not Leave Detrimental Impacts On Knives
Unlike manual knife sharpeners, electric ones don’t leave any damage on your blades. Manually sharpening knives can leave both sides of the knife uneven and as a result, damage the knife.
Electric ones, on the other hand, can remove an even amount of metal on both sides of the blade with high precision.
Time-Saving
Sharpening a knife manually not only requires excellent skills but also time. However, with an electric knife sharpener, you can save a lot of time. All you have to do is plug the sharpener in, stick the blade into the slot, and carefully drag the knife out.
Virtually Hazard-free
As stated above, when sharpening a knife with an electric knife sharpener, all you need to do is to drag the blade through the slot meticulously. There’s virtually no risk involved, which means that it’s highly unlikely that you’ll cut yourself by accident. The same cannot be said for manual sharpeners though, as a lot of them require you to hold the blade in the process of sharpening.
High Versatility
This is my personal favorite feature of electric knife sharpeners. Depending on the model, a lot of them can sharpen a wide variety of knives, ranging from serrated knives to kitchen ones. Furthermore, a lot of electric knife sharpeners can even sharpen scissors and many other things as well.
What Are The Best Electric Knife Sharpener Brands?
There are numerous electric knife sharpeners out there, and not many can claim the spot of the best electric knife sharpener manufacturers. While some of you might not particularly care about brand names, I think it is fair that you’re informed of what name to trust.

Buying Guide
Budget
Budget is an important aspect to consider before buying anything. Knowing the limits of your budget will help you narrow down the search a lot.
While a more expensive product usually provides a better service, it does not necessarily mean that a cheap electric knife sharpener will make a lousy choice. As long as you read the description carefully to know that the sharpener is suitable for you, chances are that you will be able to find a suitable one within the limits of your budget.
How Many Stages Does It Have?
Different models have different numbers of sharpening stages, varying from 2 to 4 stages. Usually, the first state is for pre-sharpening your knives while the second one is mostly for polishing.
What Is The Angle Of The Sharpening Slots?
Some people might not notice this, but different knives used for different purposes usually have different angles. Some electric knife sharpeners can only sharpen your knife to a certain angle, with the most common angle being 20 degrees. For the majority of American-style kitchen knives, this is the standard angle.
However, there are different models that offer an adjustable sharpening angle, ensuring that you can sharpen your knives with any degree between 15 to 30. As promising as this sounds, a more advanced electric knife sharpener usually means a more expensive product.
Some of you might be confused, thinking “But doesn’t a sharper angle mean a sharper knife?”. Well, not necessarily. Sharper knives usually are more delicate, which means that they need considerably more maintenance and you need to handle them with more care.
If you’re not too sure what angle you should sharpen your knife to, then check out the table below. As long as you know what type of knife yours is, then you should have no problem with sharpening your knife after consulting this table.
Fillet knife | 12°-18° |
Paring knife | 12°-18° |
Razor | 12°-18° |
Japanese-style knife | 14°-16° |
Sporting knife | 25°-30° |
High-quality chef’s knife | 12° |
Majority of American-style kitchen knife | 15°-25° |
What Is The Abrasive Made Of?
Electric knife sharpeners’ abrasives are made of various materials, the three most common of which are diamond, ceramic and sapphire.
Usually, the majority of electric knife sharpeners use diamonds for their abrasive. Because diamond is the hardest natural material, it can remove metal much faster than any other material. Therefore, diamond is undoubtedly a good abrasive material choice for coarse and medium-fine grinding.
Ceramic is an ideal alternative to diamond. Even though not as hard, ceramic can be employed for electric knife sharpener’s final stages like polishing and honing blades.
Similarly, sapphire is another choice for diamond substitute. Being one of the hardest materials, sapphire can remove metal from steel blades with relative ease.
Do They Include Any Safety Features?
Working with a sharp knife is dangerous, and sharpening a knife is just as equally so. Nobody wants to accidentally nick or stab themselves while in the kitchen. It’s best that you should find an electric knife sharpener with a safety feature that ensures you have a hazard-free sharpening experience.
If you’re wondering what a safety feature for an electric knife sharpener might be. Well, let me tell you that the most common one you’ll find is a rubber non-slip base or a rubber-grip handle. With a non-slip sharpener, chances are that you will never encounter a sharpening accident.
Is It Versatile?
If you don’t have a wide variety of knives back at home, it’s best that you determine what kind of knife you’re using the most. Why? Because it’s the knife that chooses the sharpener, not the other way around. As I’ve said before, different knives need to be sharpened to a different angle, and not every sharpener can sharpen your knives to the required angle.
Furthermore, knives can be made of different materials such as steel, alloy,… If you have many different types of knives, then it’s best that you get an electric knife sharpener that can take care of all your blades. It would be a big hassle to get a different sharpener for a different knife.
Ease of Maintenance
When you sharpen your knives, there will be metal residues left behind. Most electric knife sharpeners can’t withstand direct contact with water, let alone dishwasher safe.
So how can you clean out the metal residue in the machine?
Well, one choice is to use a magnet to collect all the remaining metal, but this can take too much time and there’s no guarantee that you’ll get all of the residues out. The best bet you can have is to find an electric knife sharpener with a removable, magnetic tray that can collect all the metal particles.
