On December 9, 1942, during the Second World War, KA-BAR presented a knife to the United States Marine Corps in the hope of it becoming the standard weapon. In collaboration with the Marine Supply Department, the project was revised and the production of an improved combat and utility knife began.

During the war, USMC KA-BAR knives became so renowned for their quality and abundance that "KABAR" became the common name. It was adopted by the Marines, Army, Navy, Coast Guard, and Underwater Demolition Teams. Years later, many KA-BAR knives were reactivated in Korea, Vietnam, Desert Storm, and the wars in Iraq and Afghanistan.

In 2019, KA-Bar joined forces with Spartan Blades to establish Pineland Cutlery. CEO John Stitt aimed to create a "KA-BAR" with enhanced strength, robustness, and corrosion resistance. During development, metallurgist Larrin Thomas identified CPM MagnaCut® steel with the desired qualities.

CPM MagnaCut® is a sintered high-carbon steel produced by Crucible Industries and specially designed for blades. Spartan Blades developed the Spartan-KA-BAR using CNC machining, cryogenic treatment, and PVD coatings.

Japanese steel merges with Italian excellence

For this new collaboration between Coltelleria Collini of Busto Arsizio and Fox of Maniago, we have chosen the Rimor model. Only 9 exclusive pieces of this excellent bushcraft knife produced by Fox of Maniago have been made, using for this edition the 5 mm Sanmai V-Toku2 steel produced by the Japanese Takefu Steel instead of the Niolox used in the standard model.

Specifically, the central plate is the carbonaceous V-Toku2 at 62/63HRC and on the outer cheeks there is the stainless SUS410, so as to guarantee not only a beautiful aesthetic effect, but also a very high cutting capacity, penetration and edge-holding capacity together with easy resharpening and maintenance. At the same time, the blade has a remarkable resistance to corrosion and an important increase in resilience due to the extreme steel type and rolled structure.

Special limited edition model created on the occasion of the XXV Anniversary of Extrema Ratio

Extrema Ratio Misericordia Black Warfare is a version in a limited series of only 500 pieces that preserves intact all the features of the famous Misericordia model adopted by the 4th Alpine Parachute Regiment, which helped develop and test the product and chose it for its unique characteristics that make it particularly suitable for ambush combat.

The blade is milled from Böhler N690 steel, hardened to 58 HRC for the best balance of edge retention and strength, is 118mm long, 4mm thick, and has a flat edge. The weight of the knife is just 87g. It has a spear-point profile, with a full-length shank that makes it even lighter, features ¾-length false counter-wire, and has a Black Warfare finish, with the innovative and original Extrema Ratio Geotech Camo pattern, made by laser engraving.

The handle retains the unmistakable Extrema Ratio ergonomic profile, and is made of fiberglass-filled nylon to ensure absolute robustness in all conditions, even in the heaviest of uses. The distinctive ring on the bottom of the grip aids hand grip by allowing the soldier a greater and firmer lunge, exponentially increasing the combat potential of the Misericordia.

The Kydex scabbard offers belt-clip, ulti-clip and malice-clip attachment options. In addition, it is possible to attach the scabbard to the M.O.L.L.E. system by braiding the paracord lanyard. The Misericordia Black Warfare comes in an IP67-certified watertight Polypropylene technical case, with pressurization valve, weatherproof, dustproof and shockproof, inside of which is also the Kydex sheath, double UTLICLIP, double-grit sharpening plate (ceramic abrasive and synthetic diamond) and metal plaque with the progressive number of the limited series.

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

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.

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.

- 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.

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.

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

SHRAPNEL OG is a truly multi-purpose "back-up", with strong combat attitudes. The leaf blade is characterized by a wide flat winding, with a narrow sharpening angle which makes it particularly sharp. The rigid sheath can be positioned horizontally, vertically or inclined at 45 °. The SHRAPNEL OG is produced without the top guard.

Use: tactical, sports, hiking, collection

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)
Handle: forprene
Blade length: 90mm.
Blade thickness: 6.5mm.
Total length: 210mm.
Balancing: set back to 0.5cm. from the guard branch
Weight: 190g.
Sheath: ABS with Tek-Lok multiposition attachment
Notes: Numbered edition - cardboard box with Extremaratio logos and certificate

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.

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.
