The most important tool to a chef in the kitchen or any home cook for that matter is their knife set. Any of these knives, especially the chef knife, will be in constant use more so than everything else. So, it’s no wonder why you would want your knives in tip top shape.

A high-quality knife can be quite pricey so taking care of the knife is crucial. Sharpening and honing the blade’s edge is a daily routine to any chef. For the most part, people use a sharpening stone or sharpening steel. But if you want to get a really sharp edge, then you will want the best electric knife sharpener available.

While a sharpening stone or whetstone is a great way to sharpen your knives, it does take a lot of practice to get the edge perfect. Sometimes the whetstone will not possess the capability of sharpening the knife’s edge as close as you would want it. Here is a video to show the difference between all types of knife sharpeners. An electric kitchen knife sharpener can sharpen and hone the edge so close it is almost paper thin! Well maybe not that thin, but there are some that can do 5-degree angles which is still pretty close. This is very important when sharpening a fillet knife or a very flexible blade. They are also able to do all kinds of knives, not just kitchen knives such as hunting knives, hatchets, scissors and lawn mower blades.

Utilizing an electric knife sharpener will also create a safer work environment for you. With the knives you are using, there will be fewer accidents and injuries. Some say that the most dangerous thing in a kitchen is a dull chef knife. Well, that is actually true. If the blade’s edge is dull when you go to try and cut something denser or solid, the blade could slip, cut a different direction or require heavy chopping which could result in injury to yourself or others. This happens way too often. To learn more about how to properly use an electric knife sharpener, check this video.

In this article we will go over what you need to know about electric knife sharpeners before purchasing one as well as some of the cool features you may want. We will also cover some of the electric knife sharpeners available on the market today.

How to Choose the Best Electric Knife Sharpener

An electric knife sharpener is not a cheap item to purchase but will serve you well in the years to come as long as you make the right decision. You will want to know everything there is to know about the machine before you make a purchase.

As with buying any item online, you are not able to touch it or use it before buying, which is kind of risky when you are purchasing something with moving parts.

Some models may not offer the capabilities you need to hone your knife properly. For instance, some of the electric knife sharpeners are meant to be used in a home. While others have the capability to be used in the commercial kitchen setting.

Capabilities

Knife sharpeners are pretty versatile, although some do lack some of the cooler features the high-end models possess. A feature that may be on one model may not be on all models.

One of these features is the ability to change the grit of the roller or the plates. This allows you to be able to sharpen all different kinds of knives. Heavy plates or a coarser grit is perfect for grinding stainless steel and the harder metals. But if you wanted to sharpen carbon steel knife you would need to use smoother rollers or a softer sharpening stone. High carbon knives are more widely used among chefs. A high carbon steel knife is a softer metal that can be brittle which can easily break or chip when sharpening incorrectly. That is why the actual stones or belts sharpening the steel need to softer. It would be a bad day if you happened to break your knife because you were unable to change the grit settings on your electric sharpener.

Most models have several different slots for different settings for angle and grit. In some cases, one electric sharpener may be able to sharpen serrated knives. Serrated knives are very hard to sharpen and must be done by hand.

Construction and Design

For the most part, the machines are not much to look at and there really is not any room for improvement aesthetically. They are more or less just a box that plugs into the wall that pretty much looks like a toaster. However, there are some that look better than others.

The design is really not what is important, the construction and integrity of the machine is what matters. You will want a strong and sturdy electric knife sharpener that will do the job in the most efficient way possible with little to no mishaps.

Make sure the device is not prone to shaking or become unstable within use. This can be very dangerous and needs to be avoided. Get an electric knife sharpener that will also grind the knives without making too much noise or creating too much of a mess at the same time. Some machines have a tendency to spit the metal shavings about.

Having a catch-all or a guard will help to prevent this from happening.

Coincidentally, the higher end models are usually made by actual trusted knife makers that have been making knives for decades. So, if they make a quality knife then most likely, they make great knife sharpeners as well. This is a good rule of thumb to remember and consider when purchasing an electric knife sharpener.

Warranty

A warranty will help to protect your electric knife sharpener when it breaks. A quality knife sharpener will come with a lifetime warranty if they are confident it will last forever. If it doesn’t, then you should probably look at other machines. There is a lot of moving parts in an electric knife sharpener and the product should be backed by some kind of guarantee.

The Worst Electric Knife Sharpener

And last and definitely the least, we have this electric knife sharpener that you might as well throw in the trash.

The machine has the same features as the last reviewed product but with even less quality to boot. The largest fallback of them is going to be the grinding wheels.

However, this one uses sapphires instead which barely scrape the surface of the edge.

If you feel like wasting money on an electric knife sharpener, then this is definitely the way to go. The good thing is, it will only cost you twenty bucks.

Pros

  • The machine has a two-level sharpening system
  • The product is very inexpensive
