Factors to consider when choosing the best electric knife sharpeners

When picking the best electric knife sharpeners, there are a few crucial factors to consider. These factors will help you choose a quality electric knife sharpener that suits your needs. Below, we discuss the important factors to consider.

Types of knives

First, you need to have an understanding of the types of knives you intend to sharpen. Do you have straight or serrated knives? This is an important consideration to help knock out some knife sharpeners. Some sharpeners are only designed for straight knives. Using them on serrated knives can end up damaging your knives. If you happen to have both straight and serrated knives, then consider sharpeners that can sharpen both sets of knives.

Blade angles

Different knife sharpeners come with varying blade angles. This is the angle at which knives are sharpened at each side of the blade. Most kitchen knives are typically sharpened at 15 or 20 degrees. You need to consider sharpeners with these sharpening angles. However, outdoor knives that need to be stronger than sharpeners require big angles of up to 26 degrees.

In addition, you also need to consider the knife style and choose accordingly. Most American-style knives sharpen at 20 degrees while Asian-style knives sharpen at 15 degrees. It is worth noting that the greater the angle, the stronger the knife. However, sharpness reduces with big angles.

Sharpening material

There are typically two types of sharpening materials. These are the tungsten carbide and the diamond material. The diamond material is considered the best since it is extremely hard. The diamond material is also faster. The tungsten carbide features middle speed and sharpness. However, it makes a great choice when speed is not your biggest concern.

Sharpening stages

Most electric knife sharpeners work in stages ranging from stage one to stage four. The stages show the different levels of sharpening. Stage one is the most basic and delivers the coarsest sharpening. Stage one sharpeners are cheap. They remove a lot of metal hence no precision cutting. These sharpeners are ideal for outdoor slicers and knives that are totally dull.

The two-stage sharpener is the most common and one that features fine and coarse settings. You can use both stages to achieve excellent results.

Lastly, we have stage 3 and four sharpeners which create custom sharpening. However, these sharpeners are expensive and require some learning curve. Not everybody is suited to use stage 3 or stage 4 sharpener.

Final verdict

In conclusion, these are the best electric knife sharpeners on the market to seriously consider buying. They are extremely efficient sharpener with pretty exciting features. The sharpeners come highly recommended for versatile use. Make sure you maintain your knife sharpness by picking one of these amazing knife sharpeners.
