Extrema Ratio presented a knife at the IWA 2025 that was developed in cooperation with the KSK. Here are the first details.
Extrema Ratio repeatedly cooperates with international units to create knives according to their wishes. For units from Austria, for example, the “Task J” and “Glauca J1 NS” knives were created for the Hunting Command and the “E.C.M.” for the Cobra task force.
At the IWA 2025 (-> Successful IWA Outdoor Classics 2025), Extrema Ratio presented the new “MH Stealth” knife, which was developed in cooperation with the Special Forces Command (KSK). “MH” stands for the initials of the designers.
The MH Stealth from Extrema Ratio is a very light yet handy combat knife with a discreetly shaped handle and a straight blade with short serrations. A belt cutter is concealed in the handle and there is a spike at the end of the finger ring. Extrema Ratio tells us that the knife can be carried in a sheath similar to that of the “Mamba” knife. The knife should still be available in 2025.
