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 big brother while offering better portability and manageability.

The locking mechanism on opening is particularly strong as it is assisted by a safety system that turns it into a true fixed blade. The primary safety on the blade is activated by raising and lowering the locking pin. To provide the user with maximum safety in use, a practical and quick secondary safety has been applied, which can be activated simply by moving the locking pin horizontally.

For the purpose of lightening the steel frames, a template was laser-cut from the profile of the RAO C, which was then used to make a gadget that is delivered with the knife.

The Ti-Lock mechanism was originally designed to isolate the locking mechanism from the handle of the knife so that it can offer greater freedom of design. Totally ambidextrous, the Ti-Lock is not meant to be a mere exercise in style, but should be understood as a mechanical innovation and a solid and reliable testament to the passion of Chris Reeve and Grant and Gavin Hawk.

Company History.
In 1938, Rudy Ruana began making knives in a small store in Montana. Members of his family continue to this day to handcraft Ruana knives in the same store. In 1964 Ruana's son-in-law, Vic Hangas, left a job with a telephone company and put his artistic talents to good use, joining Ruana in the business. Hangas' son Mark began working in the business in 1976. In 1983, Ruana retired at the age of 80 and sold the business to the Hangas family. In 1984 Mike Hangas joined his brother and father and the company was incorporated. Rudy Ruana died in April 1986. He was honored with posthumous induction into the American Bladesmith Society's Hall of Fame in 1997 and Blade magazine's Cutlery Hall of Fame in 2002.

Ruana knives are still handmade in the small Montana store where Rudy Ruana began forging blades more than 80 years ago. In an era of outsourcing and diminishing Made in America products, Ruana knives are still handmade in the United States, with a focus on quality rather than quantity. Although some things have changed over the years, still using the same methods and much of the same equipment used by Rudy Ruana.

Knife withdrawn from private collection, dates from the very first production in 1984 (in fact, it does not indicate the patent engravings, affixed in 1985 and does not indicate the production date, affixed only from 1986). Globally in good condition, it has marks on the blade and handle due to the normal passage of time and the very aggressive scabbard which, containing a spring-loaded metal foil, irreparably scratches the blade both in insertion and extraction - It still has the factory sharpening and comes with a compass in the tang and two harpoons already engaged on the guard branch; lacking instead the box and additional accessories - Checked and certified by our in-house laboratory.

Intended Use: Sporting / Collection

Type of production: Industrial
Country of manufacture: USA
Blade: knife made entirely of 425M stainless steel

Weight: 675g.
Scabbard: black ABS
Notes: The feature, patented, is the presence of two removable screw-on harpoons/hooks. The function of these is simple anchorage. In fact, this knife can be used as a throwing hook by attaching a rope to the ring on the pommel. The manufacturer guarantees a harpoon hold of up to 600 pounds. The Navy Seals, specifically, had requested a knife that could be used underwater in order to anchor the vehicles to an underwater attachment point, and that is the reason for the total steel construction.

Each Randall model has been thoroughly tested in the field and has been shown to be properly modeled and designed for its particular use. Randall knives are 100% handmade and no two are exactly alike. The demand is so great for all models that it typically takes a few years to get the model ordered directly from Randall.

"Bo" Randall passed away on December 25, 1989 at his home. Bo and his son Gary have run the business side by side for over twenty five years. Gary continues the tradition of handcrafted knives that carry the Randall Made brand along with his children, Jason and Michael.

Japanese steel merges with Italian excellence

For this 2021 collaboration, exclusive to Coltelleria Collini, we have decided to propose a series of best sellers produced by Extrema Ratio. Knives made with the famous San Mai steel produced by the Japanese Takefu Steel. Specifically we have used the carbonaceous V-Toku2 at 62/63HRC for the central plate and the stainless SUS410 for the two external plates, in order to guarantee a very high cutting capacity, penetration and edge holding together with an easy resharpening and maintenance but at the same time the blade has a remarkable resistance to corrosion and an important increase of resilience given by the type of extreme steel and the laminated structure.

Intended Use: Neck Knife / Collector's Knife

Type of production: Industrial
Country of Production: Italy
Blade / Handle: Full, laminated Japanese steel (San Mai) with V-Toku2 (carbonaceous) cutting edge at 62/63HRC and SUS410 (stainless steel) outer cheeks
Blade finish: Satin finish
Blade length: 40mm.
Blade thickness: 3mm.
Total length: 129mm.
Weight: 55g.
Sheath: Kydex, for neck.
Packaging: Cardboard box with Extrema Ratio logos.
Notes: Numbered edition - cardboard box with Extremaratio logos and certificate - the central core of the blade and handle is made of carbon steel so it is recommended to wash/dry the knife very well after each use and protect the steel, during storage, with a light surface of lubricant to avoid rust and oxidation.

As in the ancient swords of the Japanese Samurai.

The rolled steel - imported in 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. As early as 1100, expert Japanese blacksmiths combined different materials to give Katana swords incredible cutting capabilities combined with previously unknown strength and flexibility. It is thanks to this revolutionary construction technique that the Samurai swords have been preserved until our days becoming one of the most fascinating objects made by man. Following this tradition applied to modern metallurgy, we are now 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.

Characteristics of San Mai steel: It is made of different types of metals alloyed together to create a composite that contains and intensifies the strengths of the metals individually taken:

- Longer cutting edge life
thanks to the use of high quality steels with a high carbon content (VG10, CoS, Shiro) or sintered (SPG2), in the core steel, the blade, once hardened, reaches hardness and cutting performance decidedly superior to those achieved with the use of traditional steels.

- Greater resilience
Built on the principle of Japanese swords, the 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 lateral coating (Stainless Steel).

- Improved corrosion resistance
The steel used for the outer layers (Stainless Steel) gives the blade a high resistance to corrosion. The combination of the two or more materials used by Takefu Steel generates, at a galvanic level, a structure that improves corrosion resistance even on the edge.

- Easy machining even after heat treatment
Although steel normally becomes harder after hardening, the lateral steel used in multilayer machining does not lose its softness and allows easy machining, drilling or welding even after heat treatment. For optimum blade performance, cryogenic treatment is recommended.

- Improved aesthetic performance
Knives made of multi-state steel or damask pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.
