Guaranteed excellence: only the best brands

The Extreme Ratio E.C.M. (Einsatzkommando Cobra Messer) is a fixed blade multipurpose knife, designed for operational uses for the famous Einsatzkommando "Cobra" special unit of the Austrian police, whose logo is laser engraved on the heel of the blade. The Extreme Ratio E.C.M. it combines the characteristics of a practical tool and those of a reliable weapon, in a compact configuration with a total weight of 240g.

The blade is made of Böhler N690 steel, hardened to 58 HRC and is 116 mm long, 5 mm thick and equipped with a flat edge. The profile of the blade is of the modified spear point type, with a false counter-thread ¾ in length on the back and a lower guard to protect the hand during use.

Both the guard and the knob have holes to facilitate the attachment of the knife to various tools or for the passage of laces. The blade has a Carbon-based DLC (Diamond-Like Carbon) surface coating making it hyper-resistant to abrasion and chemical aggression.

Given the heavy use of the tool, for the handle, instead of the usual Forprene, the more performing high-strength G10 is used.

It is fixed to the FULL TANG profile by two through screws and maintains all the known ergonomic characteristics of the Extrema Ratio handles. Being a knife designed for professional use, great importance was given to ease of port, accessibility and rapid extraction.

The polymer sheath is versatile and can be carried on a service belt or mounted on M.O.L.L.E. of tactical vests, backpacks or other equipment.
