Factors to Consider When Buying the Best Electric Knife Sharpeners

a) Knife Edges

Knives come in different shapes and sizes, depending on their specific uses. A specialized knife may require you to use a certain sharpening process. Before you start going through catalogs of electric knife sharpeners, learn about the differences in edges as these cutting parts make up the blade.

  1. A straight edge, also known as the flat ground edge, is the most popular edge used in knives. Examples include; peeling, filleting, boning, cleaver, carving, utility, and paring knives.
  2. Serrated knives have sharpened grooves running along the blade's length. This type of knife is ideal for cutting into much tougher ingredients when preparing a meal. Also, serrated blades can slice without crushing, making them suitable for soft foods. Examples include; tomato knives, steak knives and bread knives.
  3. A knife with a scalloped edge, also known as a Granton edge, is designed with hollow indents along its side. These features prevent food from latching onto the surface of the blade. If your food items are sticky or wet, these knives will come in handy. Examples include; salmon blades and Japanese-style santoku knives.
  4. Hollow ground edge blades are originally from Japan, and they are one of the sharpest types of knives. The edge is formed from the blade slimming down from the middle part to make the end impressively sharp. However, the design comes with drawbacks as the knives require frequent maintenance because they are more susceptible to breaking and wearing. Examples include the Nakiri knives.

b) Blade Material

The material used in making the blade determines its longevity, sturdiness and sharpness. Knowing the composition is critical to figuring out the ideal method of sharpening the knife.

1. Stainless Steel

Most knives are made from stainless steel as the material is known for its strength and ability to resist corrosion and rust. The composition of these blades includes iron and carbon with a chromium top layer for a glimmering finish and protection against stains.

Since stainless steel is popular, it can be tricky to find a knife made with the right elements in the alloy. Consequently, the knives might prove challenging to handle when sharpening. Plus, some electric knife sharpeners can damage the blade.

2. Carbon Steel

The carbon steel material combines carbon and iron minus the chromium layer associated with stainless steel-style knives. Although these types are not shiny, their exceptional sturdiness and stiffness ensure you do not have to take them through the sharpening process often.

If you want to use electric sharpeners, it is best to look for one with tough, abrasive materials. The carbon and iron alloy can be challenging to sharpen. Luckily, these blades are low maintenance!

3. Ceramic Knives

Hardened zirconium dioxide is the main material used in ceramic knives. The material has no magnetic properties, is not metallic and may have another coating for enhancing its longevity. Chef's knives are typically made from zirconium dioxide because they are lighter and more hygienic.

A ceramic blade can feature a unique pattern and color details that add a bit of flair to your kitchen knife collection. Unfortunately, the decorations and general fragility of these knives make them especially tricky to maintain. A special sharpening process is critical to ensure you do not damage the knife or ruin the designs.

c) Abrasive Material

The abrasives, or sharpening wheels, are used to grind the knife's edge. The following are the most common abrasives used.

  1. Diamond abrasives are the hardest and most durable material used in electric sharpeners. You may need to spend more to own a product that offers high-quality sharpening wheels.
  2. Sapphirite abrasives provide comparable features to diamond abrasives. However, this material is more affordable, and thus, it is popular with manufacturers of electric sharpeners.

Polished ceramic, bonded synthetics, and carbide tungsten are other abrasives used in sharpeners. However, their ability to perform falls far below the level offered by diamond and sapphirite materials.

c) Sharpening Slots Available

The sharpening slots in electric sharpeners have grinding wheels or belts that have varying levels of grit. Typically, most devices will come with two slots: one for repairing damaged or dented knives while making them razor-sharp, and the other one polishes and hones the blade.

Electric knife sharpeners with three sharpening slots allow you to be more precise with maintaining your blades. Nevertheless, these devices are not as durable since they have more moving parts.

d) Safety Features

The best electric knife sharpeners offer ample safety features. For starters, they should have rubber feet to stop them from sliding off the counter while you sharpen your knives. Additionally, they should come with angle guides for keeping the blades in place.

An ETL certification is a plus, and devices that meet this criterion will not work if you insert the blade incorrectly.

Moreover, it would help if you looked out for sharpeners that allow you to grip them while working.
