Which knives should not be sharpened: 3 types of knives that the procedure will only harm
Such an integral “accessory” of any kitchen as a knife, over time loses those properties for which it is so valued.
Knives can become dull due to both continuous use and improper use, as TUT NEWS explains .
However, not all cutting tools can be made sharp again at home.
Thus, it is believed that sharpening is not required at all for ceramic knives, since their hardness is only slightly less than the hardness of corundum.
However, this does not mean that ceramics do not dull. If you want to restore the former sharpness of your knives, contact a specialist who has a suitable sharpening machine at his disposal.
You should also do the same if you are using a serrated knife, that is, a knife with a serrated blade.
It is unlikely that you will be able to sharpen a serrated cutting edge yourself - at best, you will resharpen it to a regular edge.
Finally, some knives have a special coating on their blades, the purpose of which is to increase the resistance of the cutting edge to abrasion.
If you unknowingly remove this protection during the sharpening process, the knife will become dull much faster.
