The hardness level is 60 (±1) HRC (a knife with a hardness above 56 HRC is considered good).

It is recommended to make cuts on wooden or plastic cutting surfaces. Glass, stone, and marble cutting surfaces are unsuitable as they can cause permanent damage to the knife blades.

Wash the knife with warm water before using it for the first time. After each use, make sure to wash the knife immediately (with a mild detergent) and dry it with a soft cloth. Especially if you have cut acidic foods, you should wash the knife immediately after use.

For your own safety, you should always wipe the knife away from your body and away from its edge, using a cloth or towel.

It is not recommended to wash it in the dishwasher but by hand, in order to protect its material and maintain its sharpness for a long time.

You can tell if your knife cuts well with an easy test using the knife and a sheet of paper. A sharp knife can easily and cleanly cut through a sheet of paper. On the other hand, a knife that needs sharpening will struggle and its cutting will be rough.

It is also advisable to sharpen your knives with a professional occasionally, to repair possible damage to the edge of the blade and to maintain sharpness.
