Why Do You Need To Get Rid Of Old Knives?

And if we look at it correctly, having a dull knife can be the worst thing you can absolutely have it a fast-paced professional environment. Electric knife sharpeners are simply the only solution to this problem, since not only do they do the job very quickly, they also do it effectively.

In the following parts, we are going to explore exactly what best electric knife sharpeners are which aspects make them good. Curious? Then keep reading on!

Chief Features To Look For When Buying The Best Electric Knife Sharpener

Best Electric Knife Sharpener

Just as in any product, there are always characteristics and features that will determine how much money you need to spend. Apart from that, knowing these characteristics will also help you in determining what you need in an electric knife sharpener.

In this section, we are going to name some of the most important features that you need to look out for when buying a high-quality knife sharpener. Now let’s find out, shall we?

Knife Blade Slots

The next step when it comes to finding out which sharpener is the best is to determine how many slots you need. Cheap ones will usually come with only one or two blade slots, which is alright if it fits your needs.

But on the other hand, you also have sharpeners that can have 5 slots for the blades. But why is this important? Well, basically you can have multiple stages of sharpening where each stage will do a different process. One stage might grind the blade itself on a hard surface while the other stage might smooth it or polish it.

Another aspect of this is that some slots may offer you different angles of sharpening. This is extremely good if you plan on using multiple kinds of knives that may need different angles to do the job correctly.

Sharpener Size

This characteristic is probably the most important one as it decides how many features the sharpener will have. Bigger sharpeners might offer you more slots, more features and more options for specialized sorts of knives.

On the other hand, you also have small and compact sharpeners that can be as small as your toaster. This can be a pretty good portable form factor for people who don’t seek that much in an electronic knife sharpener.

Design Of The Knife

The ergonomic design of the knife itself makes it a useful product for every kitchen. With the compact designing of the sharpener you can easily make the best use of the product.

A well-designed electric knife sharpener is capable enough to keep your cutlery in the best condition. Moreover, a beautiful knife sharpener easily fits into an environment.

A sleek designed electric knife sharpener enhances the look of your kitchen and its tools. This is more important for household owners to keep their tools up to date and maintain them on a regular basis.


As a buyer, you should always look for a knife sharpener that does the job well without taking much time. Make sure that the knife incorporates both manual and mechanical sharpening elements. The knife should deliver fast and precise sharpening results on the both sides of the knife.

A Guide To Sharpening Angles

Sharpening angles are very important when it comes to electric knife sharpers as they determine which kind of knife you should use. The budget oriented knife sharpeners will be limited to only one type of angle or maybe a couple.

While on the other hand, premium priced knife sharpeners will offer you a variety of different angles, with some even being able to be custom set by the user. This will come in handy for people who might end up using a sharpener professionally.

The main idea is to split the sharpeners into two different angle groups, these ones are often standardized in most products:

  • 15-degree sharpening angle
  • 20-degree sharpening angle

Most sharpeners that have the premium quality will either offer you 20 or 15 degrees, with a total of around 40 degrees inclusive. The main point to make a difference of is that the 15-degree angle system is mainly used for Japanese types of knives.

On the other hand, the 20-degree electronic knife sharpeners are used for both European and North American style knives. When buying a sharpener be 100% sure that the manufacturer reports the exact angles. If this kind of information isn’t available we don’t recommend you to buy it.

Some of the models that we mention in the review section are going to have a custom angle which can be set by the user itself, allowing him to specialize the sharpening phase for each individual knife he owns.



Now that you both know which aspects of best electric knife sharpeners are important and which ones are the best, you can finally order one! We hope that you have researched enough to know which choice is ideal for your needs. Apart from that we also wish that you know a lot more about not just how it functions, but how will you use it as well.

But if we were to make a quick summary of the reviews section and assign the first place to just a single product, we think that it would be very hard to do. Simply put, at a $100 price point it is really hard to beat out the competition.

But we have to say that according to our own opinion, we have to recommend Chef’s Choice 120 Diamond Hone 3-Stage Professional Knife Sharpener.  just because of all the features you have and adjustments you can make. The ergonomic and stable design paired with a custom set angle button is truly something that makes it worth it.
