In collaboration with Wander Tactical we have decided to propose their new neck knife, the Raptor model, in an exclusive version with a satin blade that uses the famous Japanese San Mai steel produced by Takefu Steel. Specifically we used, for the central plate, the CoS at 61.5HRC (Cobalt Special, mechanically considered 25% higher than the already highly appreciated VG10) and the 420J2 (at 56 HRC) for the two side plates in order to guarantee a very high cutting capacity, but at the same time a remarkable resistance to abrasion, resilience and resistance to oxidation.

As in the ancient Japanese Samurai swords.

The rolled 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. 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 life of the cutting edge
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, at the galvanic level, a structure that improves the corrosion resistance even on the wire.

- Easy processing even after heat treatment
although steel normally 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, cryogenic treatment is recommended.

- Improvement of the aesthetic result
The knives made with multi-state steel or with a damascus pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.

For this new exclusive collaboration with Extrema Ratio we decided to propose a best seller in the world of cutlery, the Shrapnel model. It's a satin blade version but the most important thing is that has been used, for the first time in Italy, the famous Japanese Steel San Mai produced by Takefu Steel. Specifically, we used the CoS (Cobalt Special, considered mechanically superior by 25% compared to the already appreciated VG10) for the central plate and the 420J2 (55 HRC) for the two side plates, in order to have a high cutting capacity, but at the the same time a remarkable resilience and resistance to oxidation.

A First Production Run of 30 pieces has been made.

SHRAPNEL OG is a truly versatile “back up” knife with marked combat qualities. Its leaf-shaped blade is flat ground at a characteristically low angle to a wide, extraordinarily sharp edge. The included hard sheath can be worn vertically, horizontally or obliquely (at a 45° angle). Tthe SHRAPNEL OG hilt design does not include a guard.

Clad Metal
It is a composite metal partly or entirely diffusion bonded together of different kinds of metals.

Metal composition shows higher performance which respective materials alone do not possess and the performance complements opposite characteristics of each material, that is "compound characteristics"

Clad Effect on Cutleries

Toughness
Like Japanese swords, clad metal is hard to break or bend, thanks to the toughness as the hard steel part is clad with soft steels.
Easy to work on
Cladded structure is easy to apply on such works as forging, grinding, sharpening or polishing to make a sharp blade.

Improved corrosion resistance　　　　
Proper material combination generates electrical potential difference and it enhances the corrosion resistance on blade edge.

Better and long lasting sharpness
Steel after forging pressure makes the microscopic structure denser and improves the sharpness and ensures long lasting performance.

Resource saving
As high class steel is used only for necessary part, it is perfectly cost effective..

Easy distortion correction
As the steel is bonded with soft steel materials, its blade is hard to break and the distortion correction is easy.

Easy drilling and welding after heat treatment
Though the steel gets harder after heat treatment, the soft steel never loses its softness, enabling the material to be drilled or welded.

Design improvement
Laminated patterns or Damascus patterns appear from basis materials which are bonded with different kinds of metals.
