K390 Blade – Cryo-Treated

Cut from precision-rolled stock, this blade is made from Böhler K390 MICROCLEAN® — a premium Austrian powder metallurgy tool steel engineered for extreme wear resistance and exceptional edge retention. Its advanced composition creates a dense network of fine carbides, allowing the blade to maintain outstanding cutting performance even during prolonged heavy use.

The blade has undergone a full cryogenic treatment to optimize the microstructure and achieve a hardness of 63.5–65 HRC, providing maximum cutting efficiency, excellent toughness, and superior edge stability.
