How to sharpen ceramic knives?

Ceramic knives came to us from Japan. Somewhere 10-15 years ago, Japanese sushi masters used this kitchen tool. These knives came to the market recently and immediately won it. Why ceramic knife? The fact is that, unlike the metal "relatives", the high-tech ceramics created by nanotechnology are used in the blades of such knives.

Everyone knows that these knives are practically not getting stupid when used. But not all forever, even if it is made in Japan. And people are brewing the question, and ceramic knives, how to sharpen? It is clear that when buying such knives you need to beware of fakes. That is, if you use your “miracle - knife” for a long time, it can no longer cope with its functions, which means that a fake was bought by you. It is worth remembering that ceramic knives exist of two types: with a white blade and with a black one. All other shades speak of poor quality.

And if, after all, you have a real knife, and he was blunt? Another question is brewing, do ceramic knives sharpen ordinary sharpeners for metal knives? The answer is: of course not. Because the blade material is very hard and you will not do anything with it with an ordinary sharpener. Never use abrasive wheels for sharpening ceramic knives, as this may permanently damage the blade.

Is it possible to sharpen ceramic knives at home? Of course you can, although if you are not confident in your abilities, consult specialists. Sharpen such knives need special diamond discs. Diamond pastes are also used for high precision blade sharpening. It must be remembered that after sharpening it is necessary to polish the blade (in circles with grain, starting with the largest and ending with the smallest, do not forget to wet the blade surface with oil). Do not use a lot of effort, the blade material is very fragile!
