The Vipera with Nitrogen Steel by Extrema Ratio is the perfect tactical knife for professionals and enthusiasts seeking maximum efficiency in under 100 g. Born from the union of the Requiem (pure tactical) and the Mamba (essential survival), VIPERA concentrates deployment speed, field robustness, and surgical cutting.

Crafted with a Nitrogen steel blade, it offers exceptional edge retention and even greater corrosion resistance than M390. The elongated drop‑point profile and full-flat grind allow for clean, precise cuts, while the Forprene handle ensures a secure grip even in extreme conditions. Complete with a MOLLE-compatible nylon sheath, it’s ready for any mission.

Designed for the urban‑tactical and operational world, this version leverages ultra-high edge retention, outstanding oxidation resistance, and the advanced drop-point profile guarantees an exceptional penetration coefficient. The stone‑washed blade makes the Vipera Nitrogen ideal both for tactical operators and for food-related tasks, providing surgical precision in every high‑risk situation.
