Blade #1 M390

M390 Stainless Blade – Cryo-Treated 

Cut from precision-rolled stock, this blade is made from Böhler M390 — a premium Austrian stainless steel produced using powder metallurgy technology. Renowned for its ultra-fine grain structure, M390 offers exceptional edge retention, excellent corrosion resistance, and clean, controlled slicing performance.

The blade has undergone a full cryo treatment to refine grain structure and reach a hardness of 62 HRC, making it ideal for tasks demanding long-lasting sharpness and structural integrity.
