MH-STEALTH - Extrema Ratio

MH-STEALTH is a tactical folding knife with an innovative design, developed in collaboration with the Kommando Spezialkräfte (KSK) and the Gemeinschaft Deutscher Kommandosoldaten.

The project started from a handmade drawing, which inspired Extrema Ratio and the partners involved to transform an early intuition into a compact, efficient knife designed for real operational use. The acronym MH pays tribute to the professionals who led the development of this project, while the term Stealth recalls the concealing capacity and extreme compactness of the knife.

The rigid ASPIS sheath, included with the knife and already equipped with models such as Misericordia, Mamba and Requiem, allows MH-STEALTH to be carried safely when opened, making it immediately ready to use. It is ideal for fixing the knife on a plate carrier or other tactical equipment that comes with MOLLE system.

Alternatively, MH-STEALTH can be easily carried closed inside a pocket or directly into a MOLLE system webbing – this thanks to the lack of an opening pin on the blade, which eliminates any bulkiness and allows it to fit easily and without interference in modular equipment.

The blade is made of Böhler N690 steel (58 HRC) with a burnished finish and the KSK logo engraved. It features a serration at the base that increases its effectiveness in fast and precise cuts on high-strength materials, such as ropes or reinforced fabrics. The locking mechanism is the time-tested liner lock system.

The rear ring – integrated into the handle – and the compact blade ensure manageability, control, and speed of use, making MH-STEALTH a true hybrid between a fixed and a folding knife. Designed for close combat, MH-STEALTH also adapts to everyday use scenarios, thanks to its very low weight and functionality.

This folding knife is also equipped with a hard metal glass breaker – integrated directly into the ring – and a safety belt cutter positioned in the handle.

MH-STEALTH is available in a single version with burnished blade and anodized anticorodal aluminium handle in Tactical Mud color.

MH-STEALTH contributes to supporting the Gemeinschaft Deutscher Kommandosoldaten.
