Things to Consider Before Buying an Electric Knife Sharpener

1. Type of the sharpening wheel 

It is very important to see what type of material and mechanism the sharpener uses for sharpening your knives. One common sharpening material that is used in sharpeners is diamond. When you hear 100 percent diamond abrasive, you might think that is great because it is one of the hardest materials and should be powerful enough to grind your damaged blades efficiently. While it is part of the truth, it is also a fact that diamond abrasives can be quite aggressive and might damage a delicate knife rather than sharpening it.

If you are going to sharpen knives in general, diamond abrasives are great, but if you are going to sharpen thin, vulnerable knives, make sure you are not over-grinding the blades. Another great alternative for diamond abrasives is abrasive belts, which are flexible enough to suit different types of blade materials and also different shapes of blades. So if you own exotic knives with unique material and curves, you could go for sharpeners that use flexible abrasive belts rather than a fixed stone.

2. Number of stages in the sharpening process 

Most sharpeners come with two or three sets of slots, which are each assigned for a different stage of the process, the number of stages can affect how complicated the machine is to operate, the size of the machine, and how precisely the knives are sharpened. You can go for the sharpeners with a three-stage process if you want coarse grinding, precision grinding, and polishing. If you are looking for a compact and simple sharpener, then you can opt for the ones with a two-stage process.

3. Angle Guides

As we have discussed in the previous section of our article, knife sharpening involves something called a sharpening angle. And it is great if you are an expert when it comes to knives, and you can figure out at which angle to sharpen the knives, but this is not the case for most knife users. Hence, a knife sharpener must have a way to guide your knife’s blades to the correct angle for sharpening.

4. Bevel

Another matter of concern while choosing an electric knife sharpener you need to understand the type of blade your knife has. Your choice of knife sharpener must be compatible with the blade of your knife. The types of blades are straight, serrated, double, and triple-bevel. Other common types of bevels are convex, chisel, double, flat, hollow, and saber. 

Even though electric knife sharpeners are suitable for sharpening most types of knives, you need to be extra careful while working with slim fragile blades which may not survive the aggressive sharpening nature of the wheels and can break, bend or deform.

5. Versatility

Bonuses are always welcomed and nobody minds if you have a kitchen tool that goes the extra mile to ensure superb versatility. If your choice of the electric knife sharpener can be used to sharpen other tools with edges like an ax or a lawnmower or scissors along with your kitchen knife, what is the harm? And you should know there are options out there that offer such multipurpose use so you might want to consider this as well.

6. Safety and ease of maintenance

Electric knife sharpeners can be dangerous for use if not handled properly and there to get a better grip and control over it and prevent it from slipping or skidding you need to check whether your desired one comes with a heavy base or rubber feet. This will ensure stability and keep it in one place. 

As for the maintenance, you need to go for options that come with high-grade receptacles as the process of sharpening leaves behind a good amount of metal residues that need to be collected and disposed of properly. Other than that, there is not much maintenance an electric knife sharpener requires.

5. Chef’sChoice 15 Trizor XV EdgeSelect Professional Electric Knife Sharpener

This knife sharpener from Chef's Choice is the ultimate game-changer when it comes to sharpening knives. But before we tell you about its incredible capabilities, we have to tell you a little about bevel angles.

Different knives have different shapes and angles of the cutting edge of their blades. This angle and shape determine how easily you can cut through a certain material and also the longevity of the blade. While most western knives have thicker angles, Asian knives, such as Santoku knives have a thinner angle of 15 degrees.

And nowadays everyone looks for this 15 degrees bevel angle for general cooking purposes because it allows a lot more precision, less friction while cutting, and is very sharp. What this powerful machine from Chef’s Choice does, is that it allows you to convert any knife angle into this highly desirable 15 degrees angle. This means that you do not have to travel to Japan for a single knife, or you do not have to spend a fortune on buying an expensive 15 degrees angle knife if you have this sharpener at home.

However, there is one downfall to the traditional 15 degrees bevel angle, and that is the fact that they tend to chip or break due to their thinness. The great news is that this machine has considered that and converts your knife into a 15 degrees angle with a triple bevel so that its durability is not compromised. This means that using this sharpener is hitting two birds with one stone. You get a sharp 15 degrees angle and high durability for your blades.

Although the whole process sounds very technical, there is no need to be intimidated since this machine makes it very easy for you to complete this extraordinary task. It has a three-stage process, and three different types of slots fitted to its specific purpose. The sharpening discs in the slots for the first and the second stages have been made of pure diamond abrasive and do the job of sharpening the blade, creating bevels on the knife for durability and, forming the 15 degrees angle on the blade.

Then, the third stage slots are plated with a stropping material, which gently polishes and smoothes out the sharpened knife to give the blade a smooth finish. All three types of slots have been equipped with a flexible angle guide and this means that you do not have to depend on guesswork for deciding the sharpening angle. This machine can be used to sharpen any type of kitchen knife, sporting knives, pocket knives, and even serrated knives.


  • It is not only a sharpener but also a converter in the sense that it can turn your 20 degrees bevel edges knives into 15 degrees bevel edges
  • The three-stage process ensures that the resulting blade is not only sharp but is also durable
  • The machine is easy to operate but allows you to achieve superior sharpening results
  • It has sharpening discs made of 100 percent diamond abrasives and flexible stropping material
  • The angle guides are flexible instead of fixed to help you sharpen knives of different angles with ease
  • It is very versatile
  • It can be used to sharpen serrated knives


  • Although diamond abrasives are very powerful, they are also very aggressive, so they have the risk of removing metals from your knives excessively
  • It might be harsh for very delicate knives

All you have to do is to run the knife through each of the slots and you will get a razor-sharp edge with a polished finishing.

14. Work Sharp Culinary E5 Electric Kitchen Knife Sharpener

Although at home, we use stones to sharpen knives, do you know what manufacturers and professional knife sharpeners use to sharpen a knife? They use something called an abrasive belt.

And that is the same technology used in this sharpener from Work Sharp, which means you can achieve professional and factory-level results within the comfort of your home. It uses a rotating belt with a 17-degree angle guide, which can sharpen your knives to perfection.

The advantage of a flexible belt rather than a fixed abrasive is that you can use it to sharpen many types of blades, for example, kitchen scissors, serrated blades, exotic knives, etc. It makes this sharpener a versatile device to give you complete coverage around your home. One dilemma that most users face while sharpening a knife is whether it is sharp enough. To rid you of this confusion, this sharpener has been pre-programmed to know when to stop.

Simply by a touch of a button, you can shape, sharpen, and refine your knife and it will also turn itself off when the sharpening cycle is completed. Also, you would be amazed to know the speed and efficiency at which this machine works, as it can complete a sharpening cycle within only 90 seconds! Another unique feature of this sharpener that we love is that it has a vacuum that has been built inside the machine.

When you sharpen your knives with other sharpeners, you have to make sure that you are far away from any food material because you do not want the debris from the sharpening process to contaminate your food. But since this sharpener uses its internal vacuum to suck in all the debris, you can sharpen your knives anywhere, and also with the peace of mind that your kitchen counter will be free of mess.

You might be thinking that a powerful and clever sharpener with all these features would be bigger than the others, but the interesting thing is that the truth is exactly the opposite. When you first look at these sharpeners, the first words that would come to your mind would be sleek, compact, and sturdy. This design has won this sharpener the 2018 Innovation Award. Although the sharpener is self-sufficient in bringing out the best results in sharpening your blades, it also offers a honing rod made of ceramic to give you an extra edge over your tool maintenance.

If you have been watching culinary shows, you would notice that your favorite chefs hone their knives with a rod before they start cooking. This process helps your knives to require less frequent sharpening, and also keeps the cutting edge smooth and razor-sharp at all times. The honing device also has angle guides, which will tell you the right angle for honing your knife. On the ceramic rod, there is also another slot called the MicroForge port. Running your knife through this port will make them able to cut through soft fruits, cooked meat, bread crust, and other material that are hard to cut, with ease.


  • It uses a flexible abrasive belt that turns to sharpen your knives, instead of a fixed abrasive stone
  • It is very versatile and can be used to sharpen all kinds of knives and also scissors
  • Besides the belt, there is an angle guide to sharpen your knives at the right angle

  • It uses a built-in vacuum to keep your counter clean from the sharpening debris
  • It turns itself off when the sharpening cycle is complete
  • It offers you a free honing rod made of ceramic along with a MicroForge port


  • The pre-set angle is 17 degrees and if you want to sharpen knives of other angles, then you have to buy the installations separately

Sharpening knives with an electric sharpener requires the knowledge of some technical concepts and hence we will break down these concepts in the next section so you can have an in-depth idea of electric knife sharpeners before you go out to buy one for yourself.

What is a Sharpening Angle? 

When you look at the description of many knife sharpeners, you will come across this term very often. But what does it really mean? Well, in simple terms, this means that your knife has a specific angle at which the cutting edge of the blade has been made. This angle determines how sharp and how durable your knife is. Since this angle can vary from one knife to another knife, it is important to sharpen your knife at an angle that suits the angle of your knife's edge. This can be done in many different ways.

If you are unsure about this angle, you can use knife sharpeners with an angle guide, which will ‘guide' your knife while you are sharpening it. This makes the whole process very easy since you do not have to guess what the angle of your knife might be. Another great type of angle guide is a flexible angle guide. When your angle guide is fixed, you have to be very careful while sharpening the knife so that you do not apply too much pressure or you do not move the knife awkwardly.

But when the guide is flexible, it will guide your knife with a higher efficiency and accuracy. If you are more experienced in using and maintaining different kinds of knives and would love to have control over the angle of sharpening, then you can choose sharpeners with a dial using which you can set the angle to the number that is the most suitable for the knife that you are sharpening.

You might have heard that the thinner the angle is, the sharper the blade, and although it is part of the truth, the whole picture is not as simple as that, and hence if you want to know more about the sharpening angle and how it really affects the performance and durability of your knife, it is better to have an in-depth knowledge about it before jumping onto an easy conclusion.

Sharpening, grinding, and honing – Are they the same? 

Most electric knife sharpeners have a two-stage or a three-stage process, and different slots designated for each of the stages. You might be asking why and this part will give you the answer. Although we might refer to fixing the dull edges of the knife blades simply as ‘sharpening', there are underlying parts to ‘sharpening'. First of all, coarse abrasive material is used to remove dull and damaged parts of the blade, and this is called grinding. This is the first step of your sharpening process. Then comes the honing, which is smoothening out of the blades.

When the blade is being ground in the first step, materials are removed from the blade and a ‘wire edge' is formed, which is not smooth and is also not durable. The second step, which is the honing, removes small blemishes and makes the edge more durable and hence the stone used in this step has a fine grit compared to the more coarse grinding stone. This is the reason why a good knife sharpener should have separate slots for grinding and honing, to achieve professional-level sharpening results.

How often should a knife be sharpened? 

This is one of those questions that get asked very often but has no definite answer. Figuring out how often you need to sharpen your knife is tricky because of the multiple factors that affect how often you should sharpen a specific knife. First of all, it depends on how much you use the knife. If you use a knife very frequently, it is good to hone it every week. But the other part of the sharpening, which is the grinding, does not need to be done so often, and grinding your knife too often can actually remove too much material from the blade and cause it damage.

Generally, a knife needs to be ground once or twice a year, but the polishing and honing can be done more frequently, depending on your use. Another factor that determines how often the knife needs to be sharpened is the purpose for which you are using it. For example, a knife that is used for chopping hard materials such as bones will require more maintenance than a knife used for cutting softer materials. Although it is not very easy to guess whether your knife needs honing or sharpening, there are easy ways to help you know that your knife is not sharp enough.

One of the easiest ways to tell is when your knife is squishing something soft, like a tomato, instead of smoothly cutting through it, and another way to tell is to carefully feel the blade with your thumb to see if there are any burrs on the edge. Although most of the technical aspects of electric knife sharpeners have been deconstructed for your easy understanding, the most important question still remains and that is how to choose the right electric knife sharpener. But do not worry, the next section will answer that for you since here we will discuss some of the key factors to help you judge which would be the best sharpener for you.
