This product is an elaboration of the Japanese Wakizashi sword, a typical blade 30 to 60 centimeters long, which the Samurai always carried in contact with the body, where the Katana was carried exclusively in battle.

The blade has the classic Japanese Tanto profile and is made of Böhler N690 steel with heat treatments that raise its hardness to 58 HRC for the best combination of edge hold and strength. The blade, with flat rounding, features a precious satin finish.

The handle, in black coloring, is made of Forprene while The black-colored Cordura sheath is equipped with a MOLLE system that ensures safe carrying of the razor-sharp blade by protecting it from shocks that could reduce its efficiency.

Produced in Olean, NY, in collaboration with the skilled people at KA-BAR knives, the Spartan-Harsey Kukri knife has been designed to be a highly durable hiking knife. The kukri features a blade of over 22cm, making it an all-around tool due to its center of mass, allowing the user to slice while cutting to even penetrate thick objects.

While this blade is primarily famous for its military use, the kukri is more commonly employed as a multi-purpose tool in fields and homes across Nepal. Its uses range from construction, clearing, cutting firewood, digging, butchering animals for food, slicing meat and vegetables, skinning animals, to opening cans.

It can function as a smaller knife using the narrower part of the blade closer to the handle. The heavier and wider end of the blade, towards the tip, functions as a hatchet or a small shovel.

Exclusive knife in entirely handcrafted "Comix" coloration, part of a batch of products made especially for the Atlanta 2023 Blade Show.

"Comix" type coloring refers to a coloring technique used in comic books and illustrations that is inspired by the style of traditional comic books. This style of coloring often features flat, bright colors with sharp edges between different shades. Some hallmarks of comix-type coloring include:

Flat backgrounds: Areas of solid color are applied without shading or complex tonal gradations. This gives a more "clean" and stylized look to the image.

Sharp edges: The borders between different shades of color are often marked by black or dark contour lines. These lines define the boundaries of the various elements in the image and accentuate the contrast between the different colors.

Bright colors: In comix-type coloring, bright, saturated colors are often used to create visual impact. These colors can be used to distinguish characters or to emphasize certain elements of the image.

Simplified shading: Although comix-type coloring may include shadows and highlights to add depth, these are often simplified compared to other coloring techniques. Shadows may be represented by areas of darker color or simple lines or brush strokes.

Graphic effects: Some elements of graphic effects, such as dots or speed lines, can be used to accentuate action or movement in illustrations.

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 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 easy regrinding. 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.
Selvan model: for this First Production Run a run of 5 pieces numbered from 1 to 5 was created.

The Selvans was born from the collaboration between Extrema Ratio and FISSS (Italian Federation of Sports and Experimental Survival). The project consists of modifying the Ontos, a military survival knife, to accentuate and maximize the performance of the knife as a hiking tool.

The handle has been lengthened and the blade weighted to favor the effectiveness of the cutting strokes and to make more use of the inertia of the stroke.

Intended use: Heavy Utility
Type of production: Industrial
Production Lama: Italy
Blade: integral, laminated Japanese steel (San Mai) with V-Toku2 (carbonaceous) cutting edge at 62 / 63HRC and SUS410 (stainless steel) external scales
Blade treatment: Testudo
Handle: Forprene
Blade length: 15.5mm.

Notes: Numbered edition - cardboard box with Extremaratio logos and certificate - being the cutting edge in 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 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 on 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, 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 with a damask pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.

Japanese steel merges with Italian excellence

For this 2019/2020 collaboration, exclusive to Collini Cutlery, we have decided to offer a series of best sellers produced by Extrema Ratio. Knives made with the famous San Mai steel produced by the Japanese Takefu Steel. Specifically, for the central sheet we used the carbonaceous V-Toku2 at 62 / 63HRC and the stainless SUS410 for the two external sheets, in order to guarantee a very high cutting, penetration and sealing capacity of the wire together with an ease of regrinding 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 foreign steel and the laminated structure.

FULCRUM C model: for this First Production Run, a circulation of 10 pieces numbered from 1 to 10 was produced.

FULCRUM C is the compact version of FULCRUM, it maintains all the characteristics of solidity and robustness and, thanks to the reduced dimensions of the blade (only 110 mm) and the handle, it is easily portable and concealable. The rigid sheath can be positioned horizontally, vertically or in a 45 ° inclined position. The only safety of the sheath is automatic with extraction and re-insertion by pressure, this detail makes it an intuitive and extremely fast tool, particularly suitable for emergency use and for personal defense.

Use: backup knife
Blade: integral, in Japanese laminated steel (San Mai) with cutting edge in V-Toku2 (carbon) at 62 / 63HRC and external cheeks in SUS410 (stainless steel)
Blade thickness: 6.3 mm.

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 (V-Toku2, VG10, CoS, Shiro) or sintered (SPG2), in the heart of the sheet (Core Steel), the blade once hardened, reaches hardness and cutting performance significantly higher than that 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 also 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.

Dedicated to those who are more at ease with a knife with a more classic profile, the VENOM is characterized by a wide, flat main grind.

Less suitable for combat, it is best expressed in field and precision work (thanks to the lower angle of sharpening).

It is a multirole of great utility in hunting and outdoor sports. The profile and the general outline of the blade are inspired by the Italian and Austro / Hungarian battle blades of the first half of the 20th century.

The Operator 7 is huge! TOPS Knives went well with heavy steel and handles to make a hefty, well-balanced knife. It also has those classic American fighting knife aesthetics that make it look as good as it will perform.

Made out of 5/16 "thick 1075, the differentially heat-treated blade with a very strong thorn. The entire handle is also over 1 "thick once assembled to fill out the user's hand much like an ax or hatchet handle would.

Because it is a tool, it's got to be comfortable. It's made for the men that do not back down. This knife will find its place with door kickers, survivalists, and weekend warriors alike. The rounded handles and hand guards make it a joy to use and the finger choil allows the user great precision for finer cuts. The 6.5 "of cutting edge will help you get the work done." The included Kydex sheath with dangler attachment makes it easy to carry into whatever territory you find yourself.
