Ceramic Work

A ceramic sharpener, like other knife sharpeners, work by removing a very thin layer of metal from the blade of your knife. Ceramic sharpeners are made from dense ceramic material instead of stone. They are especially recommended for sharpening very hard knives. The ceramic material used is harder than other sharpening stones, and will not wear out as quickly. Softer sharpening stones can get worn down in the middle if you do a lot of sharpening, forcing you to re-surface and flatten your stone. Unlike some other knife sharpeners, they are resistant to rust as well.

The ceramic material used in such sharpeners is as hard as glass, yet still abrasive. Ceramic sharpeners will become darker as they remove layers of steel from your knives. To return the material to its original white color, simply clean it with cleanser and water. Make sure that the ceramic sharpener is dry when you use it to sharpen your knives. Most ceramic sharpeners are designed to be used dry, unlike other sharpeners which require water or oil.

Most ceramic sharpeners are in the form of a rod or bar of ceramic material. To use these sharpeners, set one end on your work surface work surface, or hold the handle in your left hand with the knife in your right hand. Holding the knife at an angle of 20-25 degrees from the rod, slice downwards drawing the knife along the blade as you do so. Some sharpeners come in a pull-through model or angled type, which can be useful in maintaining a consistent angle as you sharpen the knife.

Some ceramic sharpeners come mounted in a wooden block at an angle. In this case, hold the knife straight down to achieve the correct angle with the ceramic rod. Spend two or three minutes on each side of the blade, keeping the knife at a consistent angle to the ceramic piece. Press gently, letting the abrasive ceramic rod do the work.

Although most ceramic sharpeners are shaped like a rod, others are in the form of a wheel or flat stone, or a pull-through model that simply requires you to pull the knife through a notch in the ceramic material. Besides form, ceramic sharpeners also differ in the grit of the ceramic material. The larger the grit, the more effective they will be against badly worn blades, because they will take off more of the steel surface of the blade. However, a finer grit is necessary for achieving a very sharp blade. One side is usually ribbed or rougher than the other. First use the knife against the rough side to begin the sharpening process. Finish by sharpening the knife blade against the smoother ceramic surface.

A ceramic knife sharpener is an easy and efficient way to bring a sharp edge back to your knives, scissors, and other cutting tools. Easy to use, it is effective on a wide variety of different knives., including straight or serrated, kitchen cutlery, scissors, and other blades. Because of its hardness, a ceramic sharpener will last for years.
