Sandvik 14C28N and Vacuum-Cryogenic Heat Treatment
The blade is made of Sandvik 14C28N steel, hardened to 60–62 HRC. Vacuum hardening combined with cryogenic treatment was used, which promotes high hardness, wear resistance, and stable steel properties during regular use.
Sheepsfoot, flat grind, and Satin
The Sheepsfoot profile provides good control over the cutting edge and is well-suited for precision tasks. The flat grind supports efficient cutting, while the satin finish gives the blade a subdued, classic look.
Black G10, Crossbar Lock, and Phosphor Bronze Washers
The handle is made of black G10. The design is complemented by gray stainless steel spacers and sandblasted steel structural components.
The pivot operates on phosphor bronze washers, while the Crossbar Lock stabilizes the blade when open. The steel clip can be mounted on the right or left side in a tip-up configuration.
