The quality of a knife is decisively influenced by the grade of steel used. The most important characteristics of the steel used to make the blade are corrosion resistance and hardness. They are achieved by the corresponding chemical composition
and appropriate heat treatment. The manufactures competence shows itself in its ability to select the appropriate steel for the intended purpose. J.A. HENCKELS has this ability thanks to its long tradition as a manufacturer of cutlery and, in the past, also as a steel producer. Different types of steel are used in the cutlery industry, of which stainless steel has become predominant during the last few decades.
