The blade is made of X50 Cr MoV 15, a widely used steel that is used in many kitchen knives. Its composition includes about 0.5% carbon (X50), which provides hardness to the knife's edge, and about 15% chromium (Cr), which provides resistance to corrosion.

In addition, it contains a small percentage of molybdenum (Mo) and vanadium (V), which provide improved wear resistance and edge retention.

Overall, this steel composition provides a knife with a hard but flexible blade, resistant to corrosion, and capable of maintaining a sharp and durable edge for a long period of time.

The handle is made of high-pressure fiberglass, G-10 and is a material with high resistance, corrosion resistant, non-slip and heat resistant. It also provides good shock absorption, helping to reduce user fatigue when using the knife. G-10 knife handles are also lightweight and easy to process.

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 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.

No matter how sharp a knife is at first, after some use it needs sharpening, something that you can achieve with a sharpener, sharpening stone or strop.

You can tell if your knife cuts well with an easy test using the knife and a piece of paper. A sharp knife can easily and cleanly cut a piece 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 fix any possible damage to the blade's edge and to maintain sharpness.
