Extrema Ratio RAO C is a compact folding knife deriving from the iconic RAO II. Thanks to its structure, RAO C is a tool that, despite its small size, manages to guarantee the same qualities of robustness and reliability as its elder brother while offering better portability as well as manageability. The handle is made of two finely crafted anodized aluminum handle scales on which Extrema Ratio applies a hard oxidation treatment, allowing the handle to be more resistant to wear and corrosion. Two steel frames help increase the strength of the handle to cope with the most demanding uses. The opening lock mechanism is particularly resistant as it is supported by a safety system that transforms the knife into a proper fixed blade. The primary safety on the blade can be activated by raising and lowering the locking pin. A practical and rapid secondary safety system was added to guarantee the user maximum safety during use; the safety can be activated simply by moving the locking pin horizontally. The reversible clip is designed to allow concealed carry inside the pocket, making the knife invisible from the outside. The blade is made of Böhler N690 steel hardened to 58 HRC with the classic Extrema Ratio MIL-C-13924 black finish. A shape with the profile of RAO C was laser cut to lighten the steel frames; this was then used to create a gadget that comes with the knife. Rao C is available in Black and Tactical Grey versions.
