- E.C.M. (Einsatzkommando Cobra Messer) is a fixed blade multipurpose knife, designed for operational uses for the renowned special unit Einsatzkommando “Cobra” of the Austrian police, whose logo is laser engraved on the heel of the blade.

This product is intended for use only by adults with knowledge and experience in handling sharp cutting tools. Improper use of the knife can result in serious injuries. The blade is extremely sharp and can easily cut through skin and tissue; therefore, extra caution should always be exercised while cutting, and hands should be kept away from the cutting edge. To prevent the knife from slipping, it is recommended to cut on a stable, non-slip surface and avoid excessive force, which may cause uncontrolled blade movement.
Leaving the knife on the edge of a table, countertop, or in easily accessible places—especially where children are present—poses a significant safety risk. The knife should always be properly secured after use, ideally by placing it on a stable surface or storing it in designated knife blocks, protective sheaths, or magnetic strips. The knife should never be used for tasks it is not designed for, such as opening cans or prying objects, as this can damage the tool and lead to dangerous accidents.
A dull blade increases the risk of injury, as it requires more force and is more likely to slip from the material being cut. Therefore, it is essential to sharpen the knife regularly to maintain optimal sharpness. Additionally, proper cleaning and drying of the knife are necessary to prevent corrosion and bacterial growth. Periodic inspection of the handle and blade is recommended to check for cracks, chips, or looseness. If any damage is detected, the knife should be repaired or replaced immediately.
When using the knife, focus solely on the task at hand—avoid talking on the phone, watching television, or other distractions while cutting. Ensure proper lighting in the workspace for better visibility and control. Please note that some countries or regions have laws restricting the ownership and carrying of knives. Before purchasing or using this knife, verify that its use is legal in your location according to applicable regulations.
Following these safety guidelines will help ensure safe and effective knife use, minimizing the risk of accidents and extending the lifespan of the tool.
E.C.M. Cobra (Einsatzkommando Cobra Messer) is a fixed blade multipurpose knife, designed for operational uses for the renowned special unit Einsatzkommando “Cobra” of the Austrian police, whose logo is laser engraved on the heel of the blade.
Extrema Ratio E.C.M. combines the features of a useful tool to the ones of a reliable blade, in a compact configuration with a total weight of 240g. The blade is built in Böhler N690 steel, hardened to 58 HRC and is 116mm long, 5mm thick and flat wire.
Blade - profile is of the modified spearpoint 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 fastening of the knife to various tools or for the passage of laces. Blade has a surface coating in DLC (Diamond-Like Carbon) Carbon-based making it hyper-resistant to abrasion and chemical aggression. Given the burdensome use of the tool, for the grip the more powerful high-resistance G10 has been used, instead of the usual Forprene. It is fixed to the FULL TANG profile by two passing screws and maintains all the known ergonomic features of the Extrema Ratio handles.
Since this is a knife realized for professional applications, great relevance was given to ease of carrying it, accessibility and rapid extraction.
Sheath - polymeric sheath is adaptable and can be carried on a service belt or mounted on M.O.L.L.E. panel of tactical vests, backpacks or other equipment.
