The legendary RAO is a durable, versatile folding knife with a blade designed for use on the battlefield and for extremely hard work. The reliable Bolt Lock blade locking system, supported by an additional bolted (from the right) steel safety bolt, effectively turns a folder into a knife with a fixed blade.
The blade - massive, extremely sharp (6 mm thick) with a short false blade and Tanto profile ensures perfect cutting edge geometry at low friction. Made of good sharpness, durable, high-cobalt stainless steel N690 with a hardness of 58 HRC made in the Austrian steel mill Böhler-Uddeholm. The blade has a non-reflective matt coating MIL-C-13924 BURNISHING. A smooth Plain blade was cut out with a flat grind. On the blade's back a long corrugated thumb ramp (spine jimping) facilitates efficient knife operation.
Double blade locking system: solid Bolt-Lock mechanism and additional protection, steel threaded bolt which should be moved and screwed through the two holes in the handle. Opening and closing the blade should be done with both hands to minimize the risk of self-mutilation, because the blade is a real guillotine because of its weight. The blade with shifted center of gravity also allows the knife to be opened quickly with a firm movement of the wrist.
Handle - full-size, as in combat knives. Anodized aluminum grip pads for a secure grip with both wet and gloved hands. Full stainless steel liners. In the rear part of the grip a hole (lanyard hole) with a stretched elastic cord with a steel pin attached. Additional notched spine jimping notches on the back of the handle for users who value an inverted grip. The steel head can act as a glass breaker and more.
Sheath - multifunctional made of wear-resistant, waterproof black nylon, fastened with DuraFlex buckle. The holster allows you to carry a folded folder and with an open blade like a knife with a fixed blade in a vertical position on the belt or on the attachment / vest using the M.O.L.L.E. system tapes Additional pocket for carrying a diamond sharpener.
