Extrema Ratio – Vipera Total Black M390
The Vipera takes its DNA from Extrema Ratio’s Requiem and Mamba models, combing their tactical and survival qualities into a single, streamlined fixed blade.
Weighing just 3.5 oz, it features a flat grind, elongated drop point blade and a Forprene handle with guard for slip-free grip. I measures it at just over 9″ overall, with a 4.25″ blade.
It is available in two different steels. This is the M390 (61 HRC) with a blued blade, but it’s also available in Nitrogen steel in Ranger Green, Black, and HCS.
The ASPIS sheath (nylon) can be attached to belts, backpacks, or PALs.
