Electric Knife Sharpener Buying Guide

Before you start shopping, you need to know the ideal qualities that a knife sharpener should possess so that you won’t buy the wrong product at the wrong price.

The days of using stones to sharpen knives are long gone. Today, there are heavy-duty sharpeners that can improve the precision of the blades they are cutting. Sharpening altering the blade’s shape so that it becomes sharp, and there are sharpeners that hone the quality of the blade and ensure the blade’s edge is straight and erect. Most sharpeners today use diamond plates, while other units use titanium and ceramic plates for particular kinds of blades.

For your kitchen knife, we highly recommend that you should use diamond plate sharpeners, as they will refine the blade your knife as sharp as possible. However, you should also consider upgraded models that come with tungsten carbide that do the job faster than traditional knives because of their dual-sided mechanism.

A good way to determine a sharpener’s quality is its versatility. Does it only work on knives or can it sharpen other things? If a sharpener can also polish household items, like scissors, then it is flexible and cost-efficiency. Of course, you won’t buy other sharpeners if the one you have can do the all the tasks already!

A sharpener should be able to accommodate your knife, regardless of its angle and size. The ability of the knife to adapt to various blades is an indicator of its quality. It should have different stages (e.g. fine and coarse) to get the kind of “sharpness” that you want.

In fact, other electric sharpeners can accommodate various types of knives, such as serrated knives, fillet knives, and the butcher’s knives. If you can get this kind of sharpener to work for you, it will make your time in the kitchen wonderful!

When you shop for electric sharpeners, you will see the term “stages”. Technically speaking, each of these stages will sharpen your knife. But at the same time, their individual sharpening capabilities is limited.

Of course, such restrictions are a good thing. If you just want a quick retouch of your knife, one of the stages is enough.

As we mentioned previously, most electric knives come with two stages. However, high-end electric knife sharpeners come with three stages that can resurrect dull and old blades in a fast and convenient way.

However, you should be wary about one-stage knives. They usually use a “coarse” stage, which tends to chip the metal of the blade and so lessens its lifespan. They are not bad, but you need to be careful when you’re using them.

When choosing a sharpener, make sure that it will serve your needs. This will save you time and money. It would be absurd to buy a sharpener for other applications. Would you get a sharpener to use on a lawnmower when you just want it for your knife? Obviously not!

Do not forget your budget either. Expensive products offer a lot of features, but you don’t need to spend too much on a sophisticated product when you just want it for a simple task. Therefore, always be wise when shopping and balance your needs with your preferences.

These are the essential aspects that you need to consider with electric knife sharpeners. Now, we will feature the ideal options for this product. Read on!
