Electric Knife Sharpener [Review & Guide]

With certainty, nobody, regardless of their expertise level in the kitchen, likes to work with a dull knife.

One needs to have the right knife which is razor-sharp and helps perform optimal chopping, dicing or slicing of various ingredients.

No matter if we were to ask a professional chef or an amateur in the kitchen, they will both say “no” to dull knives!

Though a quality knife tends to keep its sharpness and edge for a longer period of time than poor quality ones do, it will eventually lose it or it will diminish.

When this happens, it is time to catch up on our sharpening skills.

One way to get done with the sharpening fast is by using an electric sharpener. But, how to choose the perfect electric knife sharpener that will meet all of our needs?

Below, check out the list of our favorite choices for electric knife sharpeners currently.

Why Do I Need a Quality Knife Sharpener?

When you have sharp knives in your drawer, you do not just ensure optimal cutting, chopping, or slicing of numerous ingredients, but an overall satisfactory culinary experience.

But, knives don’t stay sharp forever and we need to sharpen them regularly. A knife that’s gone dull has to have its edge reshaped which will require metal removal.

An electric knife sharpener is a great option for restoring even the very dull forgotten blades in your kitchen.

Nowadays, there are a lot of different knife sharpeners that you can find, from manual to electric ones.

Thanks to their unique advantages and availability, the electric options are often the main choice of many homes and professional cooks today.

Why to Choose an Electric Knife Sharpener?

Electric knife sharpeners are designed in a way to be simple-to-use and easy-to-work-with so there’s no need for previous experience or skills to start reaping its benefits.

The abrasives of this sharpener are set on motor wheels that spin against the blade. Even though you should always stick to the manufacturer’s instructions for use, generally, they work the same.

You turn it on, hold the knife lightly, but securely and begin pulling it through the slots you want- do it slowly and smoothly.

Then, switch sides of the blade.

You will appreciate the fact that the device keeps you safe by minimizing the risk of injuries (which is not always the case with other classic knife sharpeners) and because you can use it for different types of blade materials and designs, including serrated and straight knives.

How to Choose the Electric Knife Sharpener?

Even though it may be easy to decide that you need an electric knife sharpener, especially if you prefer innovative and modern kitchen devices, finding an electric knife sharpener can be challenging.

This is mostly a result of the array of different brands and types available.

Therefore, it is important to learn the most important aspects of sharpening and the basics of electric knife sharpeners first so that you know what to expect from them. 

How often should I Sharpen My Knives?

If you use your knives on a regular basis, they usually need to be sharpened every 3 months or so.

On the other hand, for moderate or occasional use, sharpen them every 6 to 12 months. A good suggestion is to sharpen the knife after every 300 meals.

Even if you do it more often, don’t worry about any potential ‘too much metal scraping off’. This is in fact a common myth about electric sharpeners- if you’ve chosen the best brand, you needn’t worry about too much metal loss.

These sharpeners do take off metal, but this is a very small amount.

What to Know Before Buying an Electric Knife Sharpener?

Electric knife sharpeners enable honing and sharpening through rotating wheels which grind the edge.

Your task is to gently slide the blade up and down, with minimal effort, which is not the case with the manual models.

These sharpeners require more human involvement, that is, the adequate maneuvers, slight pressure, and watching out for the right sharpening angle.

Most electric sharpeners already have a set sharpening angle, so there’s no need to hold the knife at a specific angle which is often the case with manual sharpeners.

With an electric knife sharpener, this aspect is already taken care of.

What should I Know about Sharpening Angles?

When you read about sharpening blades, you often see a sharpening angle being mentioned. Since different knives serve different goals, this requires the knife to be sharpened at a specific angle.

With electric knife sharpeners, some can sharpen at specific angles.

Most of the standard models only sharpen to an angle of 20 degrees. This is the most common angle of bigger American-style knives.

Other higher-end models may come with several sharpening angle options, usually 15 and 20 degrees.

However, if you need additional angles, it’s maybe smarter to go with a manual sharpener and adjust the angle manually.

In this case, you may need a bit more experience in sharpening to achieve optimal results!

How to Clean an Electric Knife Sharpener?

Like with any other instrument, to keep it in good shape, we have to take proper care of it, including cleaning it on a regular basis. One way to do this is to use a clean and dry cloth.

Also, it’s recommendable to loosen the bottom screw and remove the cover and sharpening wheel. You then shake it upside down and use a brush to clean it thoroughly.

It’s best to do this after you’ve used it 5 times. Avoid water and lubricants for the moving parts like the motor and the wheel.

To clean the sharpening wheel, use a brush and a bit of detergent on it- scrub waste off and clean it away with a damp cloth.

From time to time, also remove the drawer below the wheels and wipe it out well using a paper towel or a damp cloth. This will eliminate all metal shavings.
