Extrema Ratio Caimano Nero N.A. Tactical Mud Aluminum Knife, Black MIL-C N690 (04.1000.0166/BLK/TM)

Caimano Nero N.A. Tactical Mud Aluminum, Black. Large folding tactical knife. Designed by Extrema Ratio for the G.O.I., Gruppo Operativo Incursori (Operational Group of the pursuers) of the Italian Navy. Its name refers to and pays tribute to the heroic Caimani Neri del Piave (Black Caimans of the Piave River), a unit of the Arditi della Regia Marina (Italian Royal Navy) that crossed the Piave River during World War I to carry out action in enemy territory.

N690 - corrosion-resistant, high-carbon 1.07% (C), martensitic chromium steel 17.30% (Cr) with the addition of molybdenum 1.10% (Mo), vanadium 0.10% (V) and cobalt 1.50% (Co) for structural uniformity. Features exceptionally high corrosion resistance and long edge retention. One of the best tool steels in the world today. Achieves a hardness of 57-60 HRC. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.

Blade - extremely sharp with Spear Point profile, 4 mm thick with clearly marked blade belly. Made of good sharpness retention, durable high-cobalt N690 stainless steel and coated with MIL-C-13924 coating. Combo type blade is derived with Flat grind which provides strength, excellent cutting edge geometry and extreme cutting performance. The serrated part of the edge allows cutting very tough cables and fabrics without losing the sharpness of the rest of the blade. Dual blade locking system: a robust Liner-Lock blade locking mechanism, is combined with an additional manual lock. A false blade is brought out on the back of the blade for improved piercing properties, in addition, at the very tip the blade is double-edged. The protruding flipper lever, when opened, forms a guard to prevent the hand from slipping on the blade.

Handle - grips made of anodized aluminum provide lightness and structural strength, to improve grip and relieve stress on the structure a number of holes were made in them. The open-backed design simplifies cleaning and maintenance. A solid left/right interleaved titanium clip allows you to carry the knife deep in your pocket (discreetly) in tip-up (tip up) position. A novelty here is the ability to mount the clip at different angles, so you can personalize the way you carry it to suit your equipment. The Handle is finished with a glass breaker.
