Best Electric Knife Sharpener Reviews 2018

What is the best knife sharpener on the market?

Cooking is fun, relaxing, and therapeutic. But, for you to feel any of these, you have to get the necessary ingredients. The other cooking essentials include crockery and yes, a sharp knife.

Nothing kills the fun in the kitchen faster than a blunt knife. Can you even imagine spending a few seconds trying to forcefully chop veggies or the steak only for you to cut your finger? Unfortunately, that’s inevitable with a blunt knife. This is why you need the best electric knife sharpener on the market.

Remember that, even though a sharp knife plays a big role in the kitchen, you will still need it outdoors. If you are a hunter, a sharp skinning knife is handy, if your garden, you may need a folding knife to prune the small outgrown branches. You will notice that regardless of the use, the knife has to be sharp.

And no, you cannot replace a good electric knife sharpener with the backside of a ceramic cup or a rock you picked outside the kitchen garden. (Yes, people still do this as a DIY but, it isn’t something you’d want to do in the middle of the night or early in the morning when fixing breakfast for your spouse).

  • It’s fast

Factors to consider when buying an electric knife sharpener

With continual use of a knife, in the kitchen, in the garden, or in the wild hunting, it will lose its sharpness slowing you down and making you prone to cuts. During this time, you will start looking for a sharpener. And, a sharpening stone, sharpening steel, or a manual fill won’t hack it you’ll need an electric knife sharpener.

Unfortunately, if you are in a rush to get this sharpener, you won’t be able to. Hurrying when shopping either leads to overspending or in the worst of cases, you’ll buy a poor-quality and an ineffective sharpener. So, if you are looking for an electric sharpener, take your time.

On the bright side, you won’t have to spend the whole day looking for that sharpener because our search reveals the best sharpeners.

The factors we considered in our quest, elements, and features you should keep in mind include:

Ability to select the sharpening angle

The two most important elements of knives are the angle and the steel strength. Western knives are known for their soft steel and a higher angle meaning that they aren’t as sharp. On the other hand, Japanese knives go with harder steel strength and a low angle meaning that they come with a sharper blade.

The high or low angle we are talking about is the blade’s bevel. The lower the angle, the sharper the knife- though appealing, a knife with a lower angle/ bevel (sharp) isn’t durable. You’d rather go for one with a higher level and less sharpness because it will last longer and it isn’t brittle.

Most knives have blades with edges ranging from an angle of 15 degrees to 20 degrees. The Japanese-style knives are the 20-degree angle knives and western/ European knives the 20-degree ones.

Mentioning these properties of knives is important as this will help you in buying the right knife and also a suitable sharpener.

On matters of the sharpening angle, the angle of the knife’s edge matters. The angle should match the angle of the sharpener for longevity and preservation of the blade. The best electric sharpeners come with different sharpening angles.

Most electric sharpeners come with a fixed angle providing precise and consistent angles.

The sharpening stages

Look for an electric knife sharpener with more than one sharpening stage. This is because each level/ stage gives you a different level of sharpness. Without it, you’d get your knife too sharp for the best performance in the kitchen or when hunting.

The stages, say, three stages make it easy for you to determine the right level of sharpness for slicing. While some electric knife sharpeners come with two sharpening stages, course and fine; the best is a three-stage sharpener or one with more than three stages.

Steer clear of sharpeners with one stage because it is often coarse, it removes more metal shortening the life of the knife.

Sharpening process

To sharpen your knife, you have to find out is the sharpener forms a burr as metal is drawn through the edge of the knife and at the knife’s tip. This burr shows the consistency of the sharpening motions. The burr also tells you if the worn out steel is being removed or not.

Serrated knives

Will the sharpener sharpen serrated knives? Are there specific instructions for sharpening the serrated knife in the electric sharpener? Note that only the finest or the last stages of electric the best electric sharpeners will prove effective for your serrated knife.


Even though most economy models of electric sharpeners have composite sharpening stones, the best and the most common electric sharpeners have diamond-based abrasive stones. You will also come across sharpeners with straightening, or fine stage made using tungsten carbide. The purpose of tungsten carbide is to protect the blade. Though at a microscopic level, the knife’s cutting edge gets straightened and realigned.

How to use an electric knife sharpener

With knowledge of the fact that dull knives are more dangerous than sharp knives, you may want to sharpen yours the right way. Too sharp and you may slice off a finger, less sharp and you may hurt yourself or take too much time slicing.

Here is how to sharpen cutlery for that polished edge with ease:

  • Place the knife’s blade on the space provided. Get the blade as close as possible to the grinding stone.
  • Slide the knife through the sharpening slot and let it rest at a 15 or a 20-degree angle.
  • Pass the blade through the groove slowly. You can do this once or twice.
  • Repeat this process on the finer stones. Remember always to begin sharpening from the coarsest stones.
  • Rinse the knife and dry it. Note that if you need to test the sharpness of the knife, you have to clean it and dry it before putting it back into the sharpening slot.

After testing several knife sharpeners (for kitchen knives and other types of knives) – not the easiest thing to do, we came to a conclusion. The best knife sharpener must be versatile, effective, trustworthy, easy to use and one worth your money.


Knife sharpening is a vital service for every chef, hunter, and anyone who handles a knife in and out of the kitchen. As mentioned above, a dull/ blunt knife is riskier than a sharp knife. Also, a sharp knife makes food preparation easier. So, you must have a reliable sharpener.
