Extremaratio - MK2.1 Knife - Black - knife
MK2.1 is a reinterpretation of a classic: a tribute to a veteran, the restyling of one of the most widespread and widely used combat knives during World War II, the Mark 2. Extrema Ratio has undertaken this ambitious project with the aim of preserving the distinctive features of the original, making only functional changes aimed at improving performance.
The blade is made of cobalt stainless steel, while the other components are made of AISI 303 and AISI 304; in the handle, glass fiber-reinforced nylon replaces the traditional leather washers. The ergonomics of the original have been maintained, but all structural parts have been oversized to obtain a massive, sturdy, and truly multi-purpose knife.
Conceptually, the most significant changes are aimed at resolving the “weak points” of the historical model: the possibility of field disassembly without tools, a modified straight Bowie tip - easier to resharpen - and grooves on the “barrel” handle, which allow the orientation of the blade to be felt even in the dark and significantly increase grip during twisting movements (screwdriver effect). Further improvements include holes for the safety lanyard and those on the guard.
The traditional blood groove has been replaced by the characteristic Extrema Ratio side groove, chosen for aesthetic and weight reduction reasons. The knife comes with a standard sheath with automatic attachment, safety flap, and thigh strap for attachment to the hip.
