Types of Knife Sharpeners

Kinds of Knife Sharpeners include the following:

Sharpening stones

Sharpening stones are either round or rectangular, and are usually one-half-inch thick.
Whetstone and the carborundum stone are the two most popular sharpening stones.
Whetstones are made of silicone dioxide minerals. They are mined and prepared to become high-grade stones. Carborundum stones are abrasive materials made of silicon carbide.

Sharpening steels

Sharpening steels have elliptical steel shafts and long, fine-textured grinding surfaces.
The knife blade is drawn in an arcing motion across the grinding surface.

Manual knife sharpeners

Manual knife sharpeners (also called manual countertop knife sharpeners) are often considered to be more efficient than sharpening steels. Most models use tungsten carbide or diamond-coated abrasive grinding stones and heavy-duty ceramic wheels.

Most manual knife sharpeners are ideal for straight and serrated knife blades. The knife is drawn lightly across the sharpening stone at a consistent preset angle. Manual countertop knife sharpeners come in right-hand and left-hand models.

Electric knife sharpeners

Electric knife sharpeners (also called electrical countertop knife sharpeners) operate automatically. They are usually electricity- or battery-powered. They are ideal for sharpening frequently-used knives.

Electric knife sharpeners are generally easy to operate but do not offer the same control level as manual knife sharpeners. Most models can sharpen straight and serrated knife blades. Most electrical countertop knife sharpeners have internal spinning wheels that grind metal blades aggressively.

Choosing Knife Sharpeners (Buying tips)

Safety features: Choose a manual or electric knife sharpener with a guard to protect your hands from getting cut or scratched.

Compatibility: Not all knife sharpeners can sharpen all types of knives, so be sure to get one that is compatible with most of the knives you own. If you want an all-around knife sharpener, choose one that can sharpen straight and serrated blades.

Materials used: Choose a knife sharpener made of steel because it can remove the tiny burrs along the blade and return it to its original condition.

Multiple slots: For versatility, choose a knife sharpener with multiple slots. One slot can be used for pre-sharpening and removing burrs, another slot for actual sharpening, and another for honing.
