Electric sharpeners are divided into professional ones and ones for household use, the latter variant is preferable for home use. These sharpeners are powered by voltage of 220V. They are equipped with a switch mode, so you can sharpen a dull knife or simply erode (polish) a sharp one. Polishing is carried out for knifes with sharp blades to keep them in working conditions. If you make regular polishing, you can avoid the extra sharpening of the knives.

If you use several knives and you are not a professional chef, we advise you to choose the manual sharpener. If your work is directly related to cooking, you use a large number of knives and sharpening takes a lot of time, it is better to buy an electric sharpener.
Diamond is the hardest material used as an abrasive for knives sharpening. If the machine is coated with diamond grit, the speed of sharpening a knife is increased by a factor of several times, but it does not provide a flatness and smoothness of sharpened material. Besides grinding with a diamond coating are expensive.
Ceramics also has enough toughness to be material for the abrasive. Ceramic abrasive sharpeners are cheaper than the diamond ones, and at work, they provide a smooth surface. Unfortunately, the speed of the sharpening is much lower, so the stones with ceramic abrasive more often are used for finishing the metal to perfection.
Natural stones as an abrasive agent were used even by primitive people.
The best known are microcrystalline quartz and silicon crystals, which are interconnected with clay.
One of the disadvantage of such abrasives is uneven sharpening.
