The Extrema Ratio MH-STEALTH Tactical Folder is an innovative folding knife developed in cooperation with the German Special Forces Command (KSK) and the German Commando Association. It is designed to be compact, efficient, and ready for real-world tactical use. The name “MH” honors the professionals involved in its development, while “Stealth” reflects its compact, low-profile design.
It comes with the ASPIS hard sheath, allowing safe carry even in the open position, making it instantly deployable. The sheath is compatible with MOLLE systems for integration with tactical gear. Without a blade stop pin, the knife maintains a slim profile and can also be carried closed in a pocket or inserted directly into MOLLE webbing.
The blade is made from Böhler N690 steel (58 HRC) with a black MIL-C-13924 finish and features partial serrations near the base for efficient cutting of tough materials such as rope and reinforced fabric. It uses a reliable liner lock mechanism.
Additional features include a carbide glass breaker integrated into the lanyard hole and a seatbelt cutter integrated into the handle. Lightweight and compact, it functions as a hybrid between a fixed blade and a folding knife, suitable for close-quarters use as well as everyday carry.
