Extrema Ratio RAO C is a compact folding knife that derives from the iconic RAO II.

Thanks to its structure, RAO C is an instrument which, despite its small size, manages to guarantee the same qualities of robustness and reliability as its bigger brother while offering better portability and manageability at the same time.

The handle is made up of 2 finely crafted anodized aluminum grips on which Extrema Ratio applies the hard oxidation treatment, which allows the handle to be more resistant to wear and corrosion.

Two steel frames help to 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 it into a real fixed blade.

The primary safety on the blade is activated by raising and lowering the locking pin.

To guarantee the user maximum safety in use, a practical and rapid secondary safety device has been applied, which can be activated simply by moving the locking pin horizontally.

The reversible clip is designed to allow concealed carry in 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.

In order to lighten the steel frames, a shape was laser cut from the profile of the RAO C, which was then used to create a gadget that is delivered together with the knife.
