S35VN Stainless Steel, Cryogenic Treatment
S35VN, made in the USA, improved from another high-end stainless steel S30V steel, is one of the most welcomed high-end stainless steels / powder steels. With uniform carbide distribution and clean steel properties, S35VN offers super edge retention and toughness and good corrosion resistance. The S35VN blade is enhanced by RUIKE using cryogenic treatment, and finally has a hardness of 58~60 HRC.
Utilizing titanium as the main handle material contributes a lot to shedding ounces, keeping rust away and offering high reliability.
