Japanese steel blends with Italian excellence

For this 2021 collaboration, between the Collini Cutlery of Busto Arsizio and the Fox of Maniago, we have decided to propose the 609OD Bushman model, an excellent bushcraft knife produced by Fox of Maniago, using Japanese V-Toku2 steel in Sanmai. produced by Japanese Takefu Steel instead of the D2 used in the production model.

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.

Notes: Special and limited edition - since the cutting edge is made of 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.

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 facing (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 damascus pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.

S.E.R.E. 2, adopted by the Operational Group of Italian Navy Incursors, is the development of the S.E.R.E. 1, created by a study group composed of Special Forces operators, martial artists and experts in survival techniques. This variant 2 has been revised according to the needs expressed by the Department.

The acronym S.E.R.E. refers to the four principles "Survival, Evasion, Resistance and Escape" which make up the training program provided to military personnel at high risk of capture.

The S.E.R.E. 2 is suitable for both tip and cut use. The unique grip, unlike the classic blades of this type, is fixed between the index and the middle, thus forming a single axis from the tip of the blade to the user's wrist, allowing its use also in reverse grip. The handle has the same ergonomics as the butt of a firearm; this grip allows an instinctive and immediate use, being able to easily integrate the training in the training activity.

The geometry of the tip ensures maximum penetration, at the same time its axial profile with a triangular base protects its resistance. The design of the blade has on one side a partially serrated profile to favor the cutting of cordages, and on the other hand a classic cut or straps that, unlike the previous model, has re-sharpening and interchangeable blades.

The central loop, which has the dual function of lightening and turn-crickets, recalls the maritime origins of its creators. The peculiarity of the knife is that it has been specifically designed to be used even without the handle; the two holes in the part dedicated to the handle facilitate assembly.

The kydex sheath has a basic retention that can be used alone for operators who need extremely fast knife use, and a removable locking lock if necessary. The knife is supplied with double safety for ambidextrous mounting. An insert with a flat-blade screwdriver is available as an accessory. Comes with belt clip for belt fastening and paracord for fixing on the M.O.L.L.E. system.

TACTICAL KNIVES MEET THE KITCHEN!

Extrema Ratio is delighted to apply the strict military standards to a range of professional kitchen knives.

The steel blade is the proven BOHLER N690, a steel enriched with chrome, vanadium, molybdenum and cobalt, hardened to the hardness of 58HRC. The handle is made of Forprene, an elastomer that is in the "NATO standard" for resistance to extreme conditions, and is completely removable from the blade; this makes possible a thorough cleaning and maintenance of the knife.

Each knife comes with its own sheath, also of military origin, which does not take into account the rules of hygiene but ensures safe transport dell'affilatissima blade and protection from shocks that could reduce efficiency. We recommend to use it only for the transport and in the event of long periods of inactivity.

Takeshi Saji was born in 1948 in Takefu (Fukui prefecture), a city located roughly in the center of Japan and in the heart of an area for centuries devoted to the production of blades. His workshop is still there, built around the oven thanks to which, for several years now, Takeshi Saji has been forging steel (especially damascus) with which he makes various models of traditional Japanese knives. The choice of materials for the finishes (mainly natural), the essential lines - evocative of use - and the chromatic combinations of rare impact make his creations unique and unmistakable in the panorama of world cutlery and, at home, they have earned him the prestigious title of Master.
