Born from the fusion of Requiem (purely tactical) and Mamba (essential survival), the Extrema Ratio VIPERA combines deployment speed, field robustness, and surgical cutting in under 100g (3,5 oz).
The elongated drop-point blade with its narrow-edge and full-flat grind glides through material like a razor, maintaining hardness (up to 61 HRC) and resilience.
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.
Developed for those facing real tactical challenges and outdoor missions, Vipera combines compactness and performance in every condition.
This version features a black handle making it 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.
