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 Compact model: for this First Production Run a run of 10 pieces numbered from 1 to 10 was created.

The lethality of the COL MOSCHIN knife in compact version. Supplied with rigid belt sheath and BELT-CLIP. The rigid sleeve can be positioned horizontally, vertically or in a 45 ° inclined position

Use: tactical, sports, hiking, collection

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.

Scimitar "or" French "blade already present in the early twentieth century, production continued until the mid-1950s. The great success of this model, which was born in Scarperia has had national diffusion, is due to the fact that although it is very light it is elegant, robust and has great cutting capacity, due to the guessed shape of the blade. It is characterized by the presence of a metal "button" on the heel and a clamp at the other end of the handle.

Craftsmanship is beautiful because it is varied

The colors of the materials with which the handmade products are made may vary from those shown in the images.
Horn, wood and cornotech are raw materials that by their nature have a marked variability from one supply to another: it is the beauty of quality materials. Add craftsmanship, where the craftsman's hand never makes the same gesture: it's the beauty of craftsmanship. Combine all this and you will always have a different and unique product. It is always different from the one and unrepeatable product that we must necessarily photograph if we want you to understand what we are talking about and what we are offering you.

The Task series has been designed for all everyday cutting jobs.

The partially symmetrical blade with flat edge on both sides. The hollow part of the blade after the guard, which separates the sharp part from the handle, has been made to house the index finger during use, creating a grip point near the sharp part for better control while using the knife.

This feature, together with the support grip on the back of the knife, allows a better grip while avoiding the slipping of the hand on the blade. This allows you to carry out most cutting jobs with higher pressure.
