T4000 S is a reinterpretation of the Japanese Wakizashi short sword that the Samurai used to carry by their side. It is an out-of-time tactical tool that does not follow any trend but faithfully respects our philosophy, aimed at meeting every functional need.
This model fits in the purest Extrema Ratio Tanto series, specifically designed for Japanese-style blade lovers who can’t let go of typical tactical accessories, such as textile sheaths and handles made of special polymers.

Description

The blade is made of Bohler N690 steel, heat treated to 58 HRC.

It is available with burnished T4000 S Black or satin (T4000 S Satin) finish.

The black handle is made of Forprene, an elastomer that meets NATO standards due to its exceptional resistance to extreme conditions. The black Cordura sheath is equipped with M.O.L.L.E. system webbings that allow to carry it on tactical vests and generic belts and guarantee safety during carry, protecting the knife from shocks that could reduce its efficiency.

Regular maintenance is fundamental to preserving the efficiency, reliability, and lifespan of your product. After each use – especially in the presence of salt water, humidity, mud, or grease residues – rinse with fresh water, dry thoroughly, and apply a suitable lubricant to metal parts and moving mechanisms. Periodically inspect the inside of the sheath, removing sand, dust, or abrasive particles that could damage the blade finish when sheathing or unsheathing.
