The 15 and 20 degree sharpening angles and the Chef Choice 1520 Electric Knife Sharpener’s precision make it the right choice for flexible Asian bevel knives. It uses the advanced spring precision angle guide to ensure the blade is perfectly guided into the sharpener regardless of whether it is serrated blades, double edge or single edge.

One outstanding feature of this two-stage sharpening tool is the advanced spring precision angle guides that serve to hold the knives for a perfect sharpening for all Asian knives. As if that is not enough, this popular product also features a 100% diamond abrasive.

Once again, this is a spendy (but less-so than the previous entry) sharpener, though it does its job very well. It’s specifically catered toward Asian knives and their particular design and makes, so if you use Euro knives, maybe opt for another in the list. It also lacks an auto-off and is a bit hard to learn, so do with that knowledge what you will.

The Benefits Of Having An Electric Knife Sharpener

The electric knife sharpener is becoming very important kitchen equipment especially as people adopt busy lifestyles. The constant rate at which knives are dulling up in the kitchen is also another reason you should invest in an electric knife sharpener. Having one will grant you a number of benefits. Let us look at some of these benefits one by one.

I. You don’t have to be skilled to sharpen your knife
Using the electric knife sharpener is one of the easiest tasks that guarantee you professional results without requiring any skills on your side. According to most of the electric knife sharpening tools and grit stones reviews, the skill level required for operating an electric knife sharpener is zero to one.

As a matter of fact, the only thing you are expected to do is follow the instructions that are laid down in the manual and are self-explanatory. Unlike the manual knife sharpener, you do not have to possess special skills on how to position and balance the blade in order to obtain the best results.

II. Electric knife sharpeners help to save time

Using an sharp knife tool sharpener saves a lot of time that you would use to sharpen your knives manually. Also, it is somehow time-consuming running around looking for professional blade sharpening services. Owning an electric blade sharpener in your kitchen will benefit you by helping you save all this time. If you do the math, you will realize that it is actually worth it having an electric in your kitchen.

The number of times you want to sharpen your knives in the middle of a kitchen task is almost countless. On the other hand, the thought of manually sharpening the blade just terrifies you because you lack the skills to get the perfect cutting edge.

III. Electric knife sharpeners save money in the long run

The economics behind purchasing an electric knife sharpener is plain and simple. If you consider the cost of hiring a professional to sharpen your knife every time it goes dull, then you will realize that an electric knife sharpener is actually cheap. The cost of an electric sharpener may be expensive at first.

However, over time, you will find out that you are saving a lot more money than a person who gets his/her knives sharpened by a professional yet the results are quite similar. Also, despite the fact that the cost of an electric knife sharpener is relatively expensive, it is a one-off expense unlike paying a professional, which is recurrent.

IV. An electric knife sharpener is multi-functional and can be used on several types of dull knives

Having an electric knife sharpener will benefit you in more ways than one. For starters, you can sharpen a couple of knife types using the same sharpener. Most of these electric sharpeners are capable of sharpening Asian, European and American and even hunting knives. They are also capable of sharpening other tools like scissors and screwdrivers.

What is more, you can use an electric knife sharpener to sharpen any knife blade regardless of the material from which it is made. For instance, you can find an electric knife sharpener that can handle alloy, carbon, metal and stainless steel materials.

V. An electric knife sharpener is more efficient than its manual counterpart

Electric knife sharpeners are fitted with grinding wheels that are powered by a motor. For this reason, you do not have to use a lot of energy and effort sharpening your knives as is the case with manual sharpeners. It is also quite easy to achieve a professional edge with an electric knife sharpener.

Most of the manufacturers that make electric knife sharpeners incorporate two stage processes. This way, the sharpener performs a coarse sharpening followed by a smooth/fine sharpening to hone the knife blades thus giving them a smooth and professional appearance. The two stages usually produce better results.

Safety Precautions

Despite electric knife sharpeners being convenient and easy to use, you still need to take the necessary precautions to avoid simple accidents. Here, we are going to share the necessary safety tips that you are expected to observe in order to obtain the best risk-free results from your knife-sharpening experience.

First and foremost, be sure to have fully read and understood the manual prior to using an electric knife sharpener. You will avoid making any mistakes if you follow the instructions according to the user manual. Secondly, you are not supposed to use water or any other lubricants with an electric sharpener. It is general knowledge that a mixture of water and electricity is hazardous.

The other important safety precaution is to avoid using the electric knife sharpener for unintended purposes. For instance, if it is not designed to sharpen scissors or serrated knives, you should avoid using it to sharpen such items. Make sure your repair any damaged cord or plug before using the electric knife sharpener. When using the electric knife sharpener, make sure the power cord is not hanging over the edge of the kitchen countertop and that it does not get into contact with hot surfaces.

You are supposed to ensure that kids are kept at a monitored distance from an electric knife sharpener. Do not use the electric knife sharpener in outdoor activities. This is because it is only meant for indoor activities. Also, when using it, make sure any kinks in the cord are straightened.

Remember to switch off and unplug the unit from the socket once you are done using it.

Electric Knife Sharpeners Buying Guide

Factors To Consider

As we noted earlier, the average consumer is likely going to encounter a few problems when confronted with the decision to buy an electric knife sharpener. This would happen because there are way too many brands of electric knife sharpeners on the market. It is, therefore, important to put some factors into consideration into account.

These factors are basically the guiding aspects that will help you decide on the best model of an electric knife sharpener to buy. This section focuses on highlighting these factors and if you are just about to buy an electric knife sharpener, this section will be quite helpful. Here are the factors to consider when buying an electric knife sharpener.

The number of blade grooves

The number of slots or blade grooves is an indication of the sharpening system that the sharpener uses. Two stage sharpeners are the most common and preferred electric knife sharpeners. This is because they utilize the best electric knife sharper system whereby the blade is taken through two stages of sharpening processes. The first stage is where the blade is ground against a flexible abrasive surface to get rid of the knife’s dullness.

The second stage is where the blade is smoothened to give it a razor-sharp edge. The number of slots should help you decide on the knife sharpener to buy. The best electric knife blade is one that comes with multiple blade slots. This is because it allows you to achieve a smoother edge through the honing stage of sharpening. Also, a multi step electric knife is preferred because it supports a wide variety of knives.

The more the number of slots in an electric knife sharpener, the more the knives it can sharpen and the higher the quality of the sharpened knife. It is worth noting that some knives cannot achieve the best sharpening quality unless you position them at a particular sharpening angle. Multi step electric knives offer the functionality to select the appropriate angle before the sharpening stages. Others will have sharpening slots with specified types of knives.

The type of Knife

The type of knives you have in your kitchen should be one of the most deterministic factors to consider when buying an electric chef knife sharpener. This is because a significant number of these electric knife sharpeners are specific to a certain model of knife. For instance, you will find a certain knife sharpener that is only meant for Asian knives.

Another one would be specifically designed for European knives. You should also consider whether the knife sharpener supports double edge, single edge, serrated blades or thick bladed knives.

The amount of worktop space in your kitchen

Although the typical electric chef knife sharpener assumes a small form factor, it is always a good practice to consider the amount of worktop room that you have. Pick a sharpener that will not use up too much of the kitchen worktop. However, it is important to remember that smaller electric knife sharpeners do not have most of the features and functionalities that you may desire.

Therefore, you should also remember that when it comes to size, there are trade-offs involved. In short, if your kitchen worktop is small, you should not buy a knife sharpener that is too big as this would compromise your space as well as the functionality of the sharpener. Depending on your need for extra features in a knife sharpener, the electric knife sharpener that you buy should correspond to the size of your kitchen

The design and features of the knife sharpener

A large number of electric knife sharpeners on the market have a lot of differences especially when it comes to design and features. Some brands have decided to completely differentiate themselves from the rest by incorporating sophisticated and innovative functions into their electric knife sharpeners. For instance, you are going to find an electric knife sharpener that is combined with a can opener, a bottle opener, a screwdriver sharpener and a groove for scissors.

You are also going to find another brand with additional safety features such as non-slip feet with grip to enhance its stability on the kitchen’s worktop. Others will have design that automatically retract the cord into a cord repository. Choose an electric knife sharpener that is equipped with the features that you are looking for.

Ease of Use

Most electric knife sharpeners have a learning curve involved before you can comfortably operate and carry out your knife sharpening tasks. However, there are those whose learning curve is bigger than others. Always buy one whose ease of use is standardized to accommodate even the slowest of learners. You can identify such a sharpener by looking at the user manual.


The cost of an electric knife sharpener is an important consideration that you should make before buying one.
