Do Electric Knife Sharpeners Damage Knives?

When too much pressure is applied to the knife, it can damage the blade. Some electric sharpeners do not have the auto-stop function that helps to control the sharpener.

You can prevent the knife from getting damaged by investing in a high-quality sharpener with safety features or not applying too much force when sharpening.

How Often Should I Sharpen My Knife?

The material and usage of the knife will determine how often you need to sharpen it. It is vital to sharpen your knife before it becomes blunt to reduce the time spent on resharpening.

High-quality knives require less sharpening because they hold up their edge for long, but low-quality knives need frequent sharpening.

What To Look For Before Buying An Electric Knife Sharpener

This buyer’s guide will help you know the features to look for when buying an electric knife sharpener. Here are some of the things to consider before buying the best electric knife sharpener that fits your needs.

Sharpening Stages

The number of stages the sharpener has must be considered before purchase. This will determine the sharpness of the knife. To maintain a razor-sharp edge, the knife must go through all the stages. Each stage has a different effect on the knife blade.

A quality knife sharpener will have more than one slot. The different stages are for a specific purpose. One of the sharpening stages must have a coarse surface for resharpening blunt knives, and the other sharpening surface must be fine grit to polish and smoothen the blade.

A 2-stage sharpener is most suited for home use, while a 3 stage sharpener is the best option for professional use.

Abrasive Type

There are majorly two types of sharpening abrasives, sapphirite abrasive and diamond abrasive. They are both great options for honing, smoothing, and polishing of knives.

Sapphirite abrasive is not as aggressive as diamond abrasive. It offers precision honing and is ideal for both delicate and thicker knives.

Diamond abrasive, on the other hand, does not offer precision grinding, and because of the hardness, it can easily damage thin knives.

Compatibility

You can find an electric sharpener with different slots for various knife-edge, size, and length.

There are limited numbers of electric sharpeners that are suitable for all kinds of knives. Most models are specifically made for only one type of knife edge. Ensure that the knife sharpener you settle for is suited for your intended blade edge.

It is advisable to buy a versatile electric knife sharpener that is suited for sharpening all kinds of blades. Such as a serrated blade, curved blade, and straight blade

Safety features

The safety features save you from accidentally injuring yourself. The safety features include a suction cup or rubberized feet, and auto-stop.

The suction cups prevent the sharpener from sliding off the working surface when in use.

Wattage

Electric knife sharpeners work with only electricity. Although many of these home appliances require much energy, an electric knife sharpener is an exception because the sharpening process takes less than a minute. Most electric knife sharpeners require 120watts.

Extra features

The extra features help you to achieve better results. These extra features are built-in guides and removable tray.

Some guides are automatic and do not require you to hold the knife when sharpening. It also prevents the blade from twisting in the sharpener.

The removable tray helps you collect the thin particles for easy cleaning of the sharpener. The disposal of small metallic debris becomes easy. Cleaning the electrical sharpener becomes swift with a detachable collection tray.
