Extrema Ratio - MH-STEALTH Knife - N690 Black & Anticorodal Tactical Mud - Tactical Folding Knife KSK
MH-STEALTH by Extrema Ratio is a cutting-edge tactical folding knife developed in collaboration with Kommando Spezialkräfte (KSK) operators and the Gemeinschaft Deutscher Kommandosoldaten.
Born from a freehand design, it has evolved into a compact, functional tool tailored for real operational use.
The name MH pays tribute to the professionals involved in its development, while "Stealth" emphasizes the knife’s concealment ability and extreme compactness.
Equipped with a Böhler N690 steel blade with MIL-C-13924 black coating and KSK logo engraving, it features a serrated section near the base for fast cutting through tough materials.
The locking mechanism is the reliable liner lock.
Its handle, made of anodized anticorodal aluminum in Tactical Mud color, includes a rear ring for a secure grip, a tungsten carbide glass breaker, and a safety belt cutter with a cutter-style blade.
The rigid ASPIS sheath allows safe carry in the open position, ideal for integration on plate carriers or MOLLE gear.
Alternatively, it can be carried closed in a pocket or directly on MOLLE systems, thanks to the absence of a blade pin.
Weighing only 106g, the MH-STEALTH is a hybrid between a fixed and a folding knife, suitable for both close combat and daily utility.
