Extrema Ratio Fulcrum S Tanto Knife Black

A robust survival knife featuring a full-tang construction, expertly designed by the renowned Italian manufacturer Extrema Ratio.

The blade showcases a modified tanto profile, crafted from premium N690 stainless steel and hardened to 58HRC. Enhanced with vanadium and cobalt, the blade's durability and edge retention are significantly improved.


Sporting a partially serrated blade with a thickness of 6.3 mm, the edge is ground with a low Flat grind. The entire blade is protected by a scratch-resistant Mil-C-13924 Black Oxide coating, which enhances corrosion resistance and minimizes unwanted glare. A dual-sided guard alongside jimping on the handle’s spine ensures a secure thumb rest and helps prevent the hand from slipping onto the cutting edge during use.



.
An ergonomically designed handle is constructed from Forprene thermoplastic, providing a reliable non-slip grip. The tang extends past the handle scales, forming a broad striker for use in emergency situations such as breaking glass or serving as a multifunctional outdoor tool. Additionally, a lanyard hole at the handle’s end allows for attaching a security cord or thong.

.
A heavy-duty sheath accompanies the knife, made from abrasion-resistant black nylon for secure belt or gear mounting. The sheath is secured at the top by a flap with a DuraFlex buckle, while the lower part features a Velcro strap for thigh attachment. The sheath is fully compatible with MOLLE system webbing for versatile carry options.
