Extrema Ratio RAO C Black Aluminum Knife, Black MIL-C N690 (04.1000.0176/BLK/BLK)

RAO C Black Aluminum, Black, a compact version of the legendary Extrema Ratio RAO knife, which was developed for the parachute reconnaissance regiment "185° Rgt. Ricognizione e Acquisizione Obiettivi" (185° RAO). Smaller dimensions translate into more comfortable carrying. Bolt Lock and lock turns the folder into a fixed blade knife.

N690 - corrosion-resistant, high-carbon 1.07% (C), martensitic chromium steel 17.30% (Cr) with 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 58 HRC. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.

Blade - extremely sharp, solid 4 mm thick false blade with Drop Point shape with clearly marked blade belly, which provides excellent cutting edge geometry with low friction. It's made of good sharpness retention, durable, high-cobalt N690 stainless steel with a hardness of 58 HRC made at the Böhler-Uddeholm steelworks in Austria. The blade is coated with a non-reflective matte MIL-C-13924 BURNISHING coating. The smooth Plain blade was derived with a Flat grind. On the back of the blade, a long notched thumb ramp (spine jimping) facilitates efficient operation of the knife.

Double Blade locking system: a solid Bolt-Lock mechanism and an additional safety feature, a slider that must be moved to completely lock the Blade. Opening and closing the blade should be done with both hands to minimize the risk of self-injury, as the blade, due to its weight, is a real guillotine. Blade with shifted center of gravity also allows you to open the knife with a decisive flick of the wrist.

Handle - full-size, as in combat knives. Grips made of anodized aluminum to guarantee a firm grip with wet hands as well as in a glove. Openwork stainless steel liners for reduced weight. A lanyard hole in the back of the grip. Additional notched spine jimping on the back of the Handle for users who appreciate an inverted grip. A two-position (right/left) steel deep-carry clip allows the knife to be carried in a tip-up position. The steel head can act as a glass breaker and more.
