As in the ancient swords of the Japanese Samurai.

Rolled steel - imported into Italy from Collini Steel directly from the Japanese Takefu Steel - is based on the ancient Japanese tradition in the creation of the famous Samurai swords. Already in 1100 the expert Japanese blacksmiths in fact combined different materials 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 the swords from Samurai have been preserved to the present day 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: These are different types of metals bonded together to create a composite that encloses and intensifies the strengths of the metals taken individually:

- Longer tool life
thanks to the use of high quality steel with high carbon content (VG10, CoS, Shiro) or sintered (SPG2), in the heart of the sheet (Core Steel), the blade once hardened, achieves hardness and cutting performance decidedly 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 lateral 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, at the galvanic level, a structure that improves the corrosion resistance even on the wire.

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

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