8 Best Electric Knife Sharpeners in 2024

Humankind has been using sharp knives long before recorded history. It means that they know how to sharpen their knives since the ancient age!

We are not going to discuss history here. We will talk about the knife sharpeners, specifically the electric ones. Yes, you heard it right.

In the past, people used handheld sharpening tools. Now, we have super smart electric knife sharpener which can do the task better and quicker.

A sharpener is a vital tool for your knife. An inferior sharpener is enough for damaging your precious knife. Therefore, settle for nothing other than the best electric knife sharpener.

In this article, we will explore the top 8 best electric sharpeners in the market. A buying guide has also been written for your convenience.

How Often Should A Knife Be Sharpened?

This is a common question asked by many enthusiasts. But, there is no specific answer to this. Actually, it depends on the frequency and the purpose of use.

The honing process usually realigns the existing edge of the blade. Therefore, it is a good practice to hone and polish the blade regularly.

On the other hand, grinding creates an entirely new edge in your blade. It is done when the blades become blunt due to heavy use.

If you need a knife for doing your everyday household chores, you should hone the blade every week. Keeping the knife clean and dry, and honing it on a regular basis will keep the rust away from it as well.

However, do not grind too often. The material may wear out if you grind the knife frequently. Thus, excessive grinding will shorten the lifespan of your knife.

You may grind your knife once in a while for any specific purpose or when it gets dull. Suppose, you have a large knife and you are going to slaughter a sheep with it. Then, honing and grinding the knife for smoother operation are very good decisions.

One major question is- how to identify when the tool needs to be sharpened?

Those who use knives regularly can tell the difference just by judging the performance. For example, if you are cutting vegetables with your knife daily, you can tell when it is not smoothly cutting through the tomato. Thus, you can sharpen it when necessary.

Another way is to check the sharpness of the blood by your thumb. This process also requires expertise. Experienced users can identify when there are bars on the edge of their blade.

To cut the long story short, honing the knife in every one or two weeks is a good practice. Grinding shouldn’t be done often as it pulls off some material in order to make a new edge in the blade.

Top 8 Best Electric Knife Sharpeners

Don’t you want to possess the sharpest, most functional knife you can get your hands on? We all do.

But, here’s the deal. No matter how great a knife you have, it will be blunt after multiple uses. Therefore, you need to have a top-notch knife sharpener.

Let’s check out some of the best sharpening tools in the market in 2020 as well in 2021. I have tried to write a short review by outlining the major benefits and shortcomings of each item.

How to Choose the Best One

Reading the best electric knife sharpener review is a good decision for those who want to shortlist the best product in the market. But, reading the reviews alone is not going to save you from making disastrous buying decisions in the market.

If you cannot make up your mind about the things to notice during the purchase, you are likely to suffer. There is an array of options in the market. So, you have good reasons to get confused.

Besides, what others are considering a very good unit may not be an ideal tool for your knife. Therefore, you should know what to look for and how to choose the best one out there.

  • Sharpening Stage

Most of the electric knife sharpeners come with two sharpening stages. The first stage has a coarse abrasive. It will help in sharpening the damaged blades. The second stage uses a fine abrasive. So, you can polish and hone the blade easily.

Some modern knife sharpener has three or more stages. The multi-staged sharpeners are rare and they often include a separate honing section.

Meanwhile, there are some sharpeners with a single stage. They are useful in sharpening small household knives quickly.

  • Abrasive Material

The best electric knife sharpener must have high-quality abrasive material as the surface of the sharpening edge. Thus, look for the one which is made with the best material. Carbide, diamond, ceramic, titanium and steel are the most widely used materials in this tool.

Diamond abrasives are the most expensive; maybe because of their unique properties. You are likely to generate heat upon sharpening your knife.

Luckily, Diamond won’t get too hot during the process. However, the material is rough for delicate knives. If the blade is thin, it may take out the metal.

Carbide is comparatively a cheaper option than Diamond. It is great for sharpening small to medium blades.

Polished ceramic and steel are also good substitute material. They will allow you to hone with more ease. Remember that if you hone regularly, you won’t have to sharpen your knife too often.

  • Angle Guide

I suggest you buy a sharpener that has an adjustable angle guide. No matter how much experienced you are, relying solely on guesswork during sharpening won’t give you an optimal result. In order to guide the knife through the right angle, an angle guide is a must. It increases both the speed and accuracy of sharpening.

  • Sharpening Slots

These slots help in sharpening the side of the blade. If the sharpener comes with the sharpening slots; it will also help them in maintaining the desired angle during honing.

  • Versatility, Quality, and Budget

Most importantly, the customers need to fix the types of knives they will be sharpening. Not all the sharpening tool will be able to sharpen a pocket knife, hunting knife, kitchen knife, and a gourmet knife.

You may also need to sharpen your scissors and other small tools. A knife and tool sharpener will be able to sharpen the tools as well.

Besides, the best professional electric knife sharpener should have the capability of sharpening different materials. After all, you are searching for the best all-around product. Aren’t you?

For these reasons, you should buy a premium sharpener. Never go for a cheap quality as it will damage your knife too.

However, a good quality knife sharpener will be costly. Therefore, determining the budget for this tool is also necessary.

  • Portability

Many people talk big about the importance of portability, but I beg to differ. The handheld sharpening tools are extremely dangerous to operate.

Therefore, I always recommend using a benchtop or stationary device of medium size. It shouldn’t be too large. Otherwise, it will be difficult to use. The good thing is that most of the stationary tools offer robust and superior performance.

  • Power System

The electric sharpeners can either be powered by an adapter or via batteries. A battery powered device will give you the freedom to use the device at any place; even during power cuts. On the other hand, there is no hassle of replacing the battery in an electrically powered device.

You should seek the middle point. The smart option is to buy a device that comes with both facilities.

  • Safety Features

Some people think the safety features are not necessary. Most of the time, they pay the price heavily by injuring themselves accidentally.

A knife sharpener is without a doubt a risky tool. Using the device involves risk. Hence, you should always look for a tool that comes with sufficient safety feature. The best electric knife sharpening system must have a state of the art safety facility.

But what kind of safety features to look for?

First, the device should be safe to move. The use of rubber feet will make the unit safe and rigid. It will prevent the sharpener from moving, reduce vibration and boost accuracy. You will be able to move the device easily as well.

Some sharpeners also have anti-slip rubber handle for ease of use. Having a flexible guide will not only correct the angle but also provide safety to the users.

Way to Use an Electric Knife Sharpener

There is a user manual equipped with new things. An electric knife sharpener also has that. It is an easy task to use an electric knife sharpener by following the user manual. If you are using it for the first time, you should be careful. And ensure that you are following the safety protections, so you don’t harm yourself or everyone around you.

Phase 1: You need to know the shape and style of the blade so that you can hold it properly. The better you know the shape of your knife, the better you would have the option to hone it. Flat knives are simple to sharpen than curves.

 Phase 2: See how your electric blade sharpener functions. Read the manual which goes with the machine. All sharpeners work differently, so you ought to know about how yours functions. So far you have used an electric knife sharpener earlier; it is wise to read the user manual for the new machine.

 Phase 3: You would now be able to continue to begin utilizing your machine.

  • Get ready: Plug it in and turn on the power. Ensure it set on a plane, dry surface.
  • Sharpen: You need to know how sharp your kitchen knives need to be and at what point you need to sharpen them. Most electric knife sharpeners start with a dense platform for dull blades, then a better stage for knives that are not too sharp or too dull, and after that, the third level for polishing.
  •  Procedure: Place the knife in the slot. Ensure you hold the knife down but do not apply pressure. Let the heaviness of the knife set and have contact with the polish. Now draw the blade gradually and reliably towards you. Ensure you are running with the ankle up to the tip of the knife. You have to go over this procedure twice on each side, which refers to a total of four times. Repeat this step in the second and third steps to advance hone and polish the knife. Switch off the power after finishing the whole sharpening process to stop the motor from overheating.

Phase 4: Now check if you have reached your preferred sharpness level. Hold a tomato in hand to test the sharpness. In case you are not happy with the pose, do the same steps again until you feel that you have got the required result. When you are satisfied, clean your knife with water and a dry towel.
