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 a 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 lateral coating (Stainless Steel).

- Better corrosion resistance
the steel used for the outer 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 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 optimum performance of the blade, cryogenic treatment is recommended.

- Improvement of the aesthetic result
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.

Designer: Laurent - LoTactical

The Tengu takes its name from a mythical creature of Japanese folklore who is represented with both human and crow characteristics, they had the reputation of being great warriors and legends say that some martial arts founders were trained by them.

- It was designed to be used in many different handles, but is particularly effective in the reverse handle.
- The design and the sheath are functional for a practical fixing and thanks to the ULTICLIP system, it can be anchored in many different options. Through the use of the paracord it can also be positioned around the neck.
- With its 5.5 mm thickness, it is extremely robust and thanks to the shape of the handle, it is comfortable even with large hands or with the use of gloves.
- Compact, robust and very functional blade both for precision cutting jobs and, thanks to the serrated part of the back, of leathery materials. The tip also, thanks to the shape of a lot, is very robust and optimal for engraving work.

As in the ancient swords of the Japanese Samurai.

The laminated 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. Already in 1100 the Japanese blacksmiths experts in fact united different materials together to give the Katana swords incredible cutting skills 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 created by man. Following this tradition applied to modern metallurgy, we can now have technologically advanced steels already tested and used in cutlery even 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 contains and intensifies the strengths of the metals individually taken:

Japanese laminated steel

- 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 slab (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 central steel (Core Steel) and the elasticity of the steel used for the side cladding (Stainless Steel).

- Better corrosion resistance
the steel used for the outer layers (Stainless Steel) guarantees the blade a high resistance to corrosion. The combination of the two or more materials used by Takefu Steel generates a galvanic structure that improves 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 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, a cryogenic treatment is recommended.

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