Extrema Ratio Vipera Total Black M390
Code: 04.1000.0484/M3/BLK/BLKRelated products
Product detailed description
Born from the fusion of Requiem (purely tactical) and Mamba (essential survival), VIPERA combines deployment speed, field robustness, and surgical cutting in under 100g (3,5 oz).
The elongated drop-point blade penetrates with ease; its narrow-edge, full-flat grind glides through material like a razor, maintaining hardness (up to 61 HRC) and resilience.
Available in two steel variants, both offer premium edge retention and corrosion resistance.
The handle, enhanced by a lower guard integrated into the blade, ensures a secure and protected grip even in the most extreme conditions, preventing your hand from slipping and guaranteeing maximum control during use. Vipera is an agile and manageable companion: invisible, yet relentless.
The nylon ASPIS sheath can be easily attached to belts, backpacks, and M.O.L.L.E systems, allowing a stable and secure knife carry, making it an ideal E.D.C. tool for tactical, urban, outdoor, survival, 4×4 off-road, camping, and beyond.
Developed for those facing real tactical challenges, urban operations, and outdoor missions, Vipera combines compactness and performance in every condition.
VIPERA TOTAL BLACK (M390 steel – 61 HRC)
Designed for the urban-tactical and operational world, this version leverages the extremely high edge retention and hardness of M390 steel, while the advanced drop-point profile ensures an exceptional penetration coefficient. The black handle and blued blade make Vipera Total Black M390 ideal for tactical operators, law enforcement, and security personnel, offering surgical precision in any risky situation.
VIPERA BLACK STONE WASHED / HCS / RANGER GREEN (Nitrogen steel)
Available in Ranger Green, Black and HCS versions, these variants are perfect for outdoor, survival, bushcraft, prepping, camping, and 4×4 adventures. Nitrogen steel guarantees stainlessness, excellent edge retention, and easy resharpening even with makeshift tools, while the advanced drop-point profile becomes indispensable for field work requiring a robust tip. This makes Vipera models with Nitrogen steel and a Stone Washed finish ideal allies in wild environments and emergency situations.
