The Extrema Ratio RAO C is a compact folding knife derived from the iconic RAO II.

Thanks to its design, the RAO C is a tool that, despite its small size, manages to guarantee the same robustness and reliability as its larger counterpart while offering improved portability and handling.

The handle consists of two finely crafted anodized aluminum scales, to which Extrema Ratio applies a hard-anodizing treatment, making the handle more resistant to wear and corrosion.

Two steel frames help increase the handle’s sturdiness to withstand the most demanding uses.

The opening lock mechanism is particularly durable, as it is supplemented by a safety system that transforms it into a true fixed blade. The primary safety on the blade is activated by lifting and lowering the locking pin. To ensure maximum safety for the user, a practical and quick secondary safety has been added, which can be activated simply by moving the locking pin horizontally.

The reversible clip is designed to allow for concealed carry in a 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.

To lighten the steel frames, a laser-cut template based on the RAO C profile was created, which was then used to make a gadget included with the knife.

With this exclusive edition of Coltelleria Collini in collaboration with Fox, it was decided to combine a multi-award-winning model such as the Suru with a Japanese steel from powders (sintered) and laminated (SanMai) by Takefu Steel.

For this project we have chosen to use Super Gold2 (SPG2) steel at 62 / 63HRC for the cutting edge of the blade in order to guarantee exceptional cutting performance and duration of the sharpening, while guaranteeing at the same time a remarkable resilience and resistance to oxidation given by the lamination process of the blade.

Notes: Opening via Carson Flipper system - Movement on ball bearings - Design by Jesper Voxnaes - Aluminum version of the SURU Carbon Fiber model, winner of the Blade Show 2018 as "Overall Knife of the Year" - Exclusive version Coltelleria Collini, Sprint Run, with Japanese stainless steel by Takefu Steel SPG2 Laminate.

The rolled steel - imported into Italy by Collini Steel directly from the Japanese Takefu Steel - is based on the ancient Japanese tradition in the creation of the famous Samurai swords. In fact, as early as 1100 the expert Japanese blacksmiths combined different materials together to give the Katana swords incredible cutting capabilities combined with a resistance and flexibility previously unknown. It is thanks to this revolutionary construction technique that Samurai swords have been preserved to this day, becoming one of the most fascinating objects made by man. Following this tradition applied to modern metallurgy, today we are able to have technologically advanced steels already tested and used in cutlery also by famous brands such as Fallkniven, Cold Steel, Mcusta, Kai, Sog, Zwilling, Rockstead, etc.

- Longer tool life
thanks to the use of very high quality steels with high carbon content (VG10, CoS, Shiro) or sintered (SPG2), in the heart of the sheet (Core Steel), the blade, once hardened, achieves decidedly hardness and cutting performance higher than those achieved with the use of traditional steels.

- Greater resilience
built on the principle of Japanese swords, multilayer steel is difficult to break thanks to the toughness of the central steel (Core Steel) and the elasticity of the steel used for the side facing (Stainless Steel).

- Better corrosion resistance
the steel used for the external layers (Stainless Steel) guarantees the blade a high resistance to corrosion. The combination of the two or more materials used by Takefu Steel generates, on a galvanic level, a structure that improves corrosion resistance even on the wire.

- Easy processing even after heat treatment
although steel normally becomes harder after quenching, the lateral steel used in multilayer processing does not lose its softness and allows easy processing, drilling or welding even after heat treatment. For an optimal performance of the blade, cryogenic treatment is recommended.

- Improvement of the aesthetic result
The knives made with multi-state steel or damascus pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.
