Japanese steel blends with Italian excellence

For this 2020 collaboration, exclusive of Collini Cutlery, 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 used V-Toku2 carbonaceous at 62 / 63HRC for the central plate and SUS410 stainless steel for the two external plates, in order to guarantee a very high cutting capacity, penetration and sealing of the wire together with an ease of re-sharpening. and maintenance but at the same time the blade has a remarkable resistance to corrosion and an important increase in resilience given by the type of external steel and by the laminated structure.

Col Moschin model: for this First Production Run a run of 11 pieces was produced, numbered from 1 to 11.

Special purpose cutting knife, specially developed for the 9th Col Moschin Parachute Assault Regiment, elite unit of the Folgore brigade.

Use: tactical, sports, hiking, collection

Blade: integral, in laminated Japanese steel (San Mai) with V-Toku2 (carbonaceous) cutting edge at 62 / 63HRC and external SUS410 (stainless steel) scales
Handle: forprene
Blade length: 160mm.
Blade thickness: 6.5mm.
Total length: 290mm.

Sheath: modular tactical, from thigh or belt, in Nylon
Notes: Numbered edition - cardboard box with Extremaratio logos and certificate - being the cutting edge in carbon steel it is advisable, in order to keep the blade in perfect condition, to protect the edge with a light surface of oil.

As in the ancient Japanese Samurai swords.

Rolled steel - imported into Italy by Collini Steel directly from 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.

Characteristics of San Mai steel: These are different types of metals bonded together to create a composite that encloses and intensifies the strengths of the metals individually taken:

- 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 with 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 coating (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.

SILENTE is the name of the knife taken from the motto "SICUT NOX SILENTES" by N.O.C.S. Central Security Operations Unit, special anti-terrorist unit of the State Police.

SILENTE was presented to the Department, the Authorities, the Minister of the Interior and the Chief of Police on the occasion of the forty-year ceremony of the foundation of the NOCS.

SILENTE is a unique model of its kind that fulfills equally unique needs: the handle is divided into two parts and creates the handle of a clamp placed in the end of the handle. With it, in addition to taking on everything that has the appropriate dimensions, it is possible to cut wire, wire, steel cables, etc. and last but not least, it can be used as a window breaker, given the tungsten carbide insert at the end.

The sheath protects the cutting edge during all these uses, allowing it to be used safely, but it can also release the blade with a fast and silent retention system. Adaptable to thigh use and applicable to the M.O.L.L.E system, it is integrated into the operator's equipment using the least possible space.

From the dynamic universe of the "Blade" film comes this authenticated and officially licensed reproduction of the "Blade Trinity", directed from the final film in the trilogy.

This piece dating back to 2005 was designed directly from the original film studio prop and measures over 30cm in length. Every detail has been precisely replicated to satisfy even the most demanding collectors.

The 16.5cm long blade is made of mirror-polished 420 stainless steel and the handle features an antique silver plated finish with solid metal parts and a black rubber handle.

Each dagger is accompanied by a black enameled wood and stainless steel display stand featuring BLADE's logo medallion, from which the blade can be removed for display.

This collectible is a must for fans of the daytime vampire hunter, Blade, played by Wesley Snipes, in his final conflict against the vampires in the film "Blade Trinity", written and directed by David S. Goyer.

The design of this military knife, sponsored by COFS (Special Forces Operative Command) in the person of General Bertolini, had already been suggested by some collectors of white weapons of the time. The restyling of the famous "paratrooper assault dagger mod. 1939 ", constitutes an important piece of Italian military history.

The knife, while borrowing the line, the structure and the proportions from the original, has been strengthened, enriched with functional modifications and made with materials with modern military specifications. The result of these few modifications is an extremely functional and effective dagger. The sheath is ankle-shaped to be worn as Italian paratroopers usually wear a bayonet.
