M390 Microclean® - martensitic high-performance chrome steel produced using powder metallurgy. Due to the alloy concept, it is characterized by extremely high wear resistance and high corrosion resistance. Thanks to its high wear resistance, it retains its edge shape, keeping the blade sharp for a very long time (requires minimal maintenance). Another advantage is its resistance to “wire” formation during sharpening. Steel with a high chromium content of 20.0% (Cr) with an admixture of 1.9% carbon (C), 4.0% vanadium (V), hardened to 59-61 HRC. This super steel is comparable to Carpenter's CPM 20CV or CTS-204P steels. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.

Vacuum & Cryogenic - the steel undergoes a specialized heat treatment process involving two key stages. Vacuum Heat Treatment - the steel is hardened in a vacuum environment, which minimizes oxidation and ensures more uniform metal properties. This process increases the strength and structural integrity of the steel. Cryogenic Treatment: After heating, the steel is rapidly cooled to extremely low temperatures, often below -100°C (-148°F). This transformation changes the residual austenite into martensite, significantly increasing the hardness, wear resistance and overall durability. Thanks to these advanced processes, the steel ensures exceptional performance, offering both razor-sharp edge retention and extraordinary blade durability.

Blade - Drop Point type, Two Tone finish, Sandblasted sharpening, rest of the blade brushed. The slightly curved cutting edge converges towards the tip of the blade. The thickness of the blade in combination with a flat grind results in an excellent cutting edge geometry and extreme cutting performance. Ceramic ball bearings ensure smooth and quiet running and support the opening of the blade by means of a pin or hole in the blade. Upper jimping on the back of the blade, a corrugated thumb rest. Locking mechanism is a robust Frame Lock with a steel inlay to prevent the lock face from wearing off.

Handle - made of solid titanium 6AL4V, beveled edges of the covers eliminate sharp edges. The slightly rough texture and engraving of the handle make the knife non-slip in the hand during use. The whole is screwed to a solid backspacer, also made of titanium. The pivot axis is decorated with a titanium cap (Pivot Cap). The single-position (right) titanium deep carry clip allows you to carry the knife discreetly in your pocket in a tip-up position (with the tip of the blade up). There is a hole above the clip for a safety or decorative cord.
