The blade of the knife is made from high-carbon stainless steel. This particular stainless steel is called CROMOVA 18, and it is quite hard so that the knives maintain their sharpness for a long time, but at the same time can be sharpened with relative ease.

The chromium content corresponds to 18% of the steel, which is why the steel has this specific name. The high chromium content contributes to the blade's resistance against stains.

The blade hardness is 58 (±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 may 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 without delay (with a simple detergent) and dry it with a soft cloth. Especially if you have cut acidic foods, you must wash the knife immediately after use.

For your safety, you should always wipe the knife away from your body and away from the edge, with 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.

No matter how sharp a knife is initially, after some use it needs sharpening, something you can achieve with a sharpener, whetstone, or honing rod.

You can determine 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 a sheet of paper. Conversely, a knife that needs sharpening will struggle and the cut will be jagged.

It is also recommended to occasionally have your knives sharpened by a professional to repair any potential damage to the blade's edge and to maintain its sharpness.
