T4000 S Ranger Limited Edition is a limited series version of only 100 pieces based on the T4000 model, a reworking of the Japanese Wakizashi short sword that the Samurai carried at all times in contact with the body.

It is a timeless tactical tool that follows no fashion but faithfully adheres to the Extrema Ratio philosophy aimed at fulfilling all functional requirements.

This model continues Extrema Ratio's purest Tanto series designed especially for lovers of the Japanese blade profile, who do not want to give up typical tactical accessories such as textile sheath and special polymer handle.

The blade, made of Böhler N690 steel hardened to 58 HRC and burnished to MIL - C- 13924, features Geotech Camo customization, Extrema Ratio's innovative and original camouflage pattern made by laser engraving.

The grip, in HCS coloring, is made of Forprene, an elastomer that is part of the "NATO standard" due to its exceptional resistance to extreme conditions.

The black-colored Cordura sheath is and equipped with MOLLE system that allows its carrying on tactical vests and general belts and guarantees the safe carrying of the razor-sharp blade by protecting it from shocks that could reduce its efficiency.

The T4000 S Ranger Limited Edition comes in an IP67-certified watertight Polypropylene technical case with pressurization valve that is weather, dust and shock resistant. Also inside is a double-grit sharpening plate (ceramic abrasive and synthetic diamond) and a metal plaque with the numbering of the limited series of 100.

Japanese steel merges with Italian excellence.

For this new collaboration, between Coltelleria Collini of Busto Arsizio and Fox of Maniago, we chose 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 Japanese V-Toku2 steel in 5mm Sanmai produced by the Japanese Takefu Steel instead of the Niolox used in the standard model. 

Specifically, the central sheet is the carbonaceous V-Toku2 at 62/63HRC and on the outer cheeks there is the stainless SUS410, so as to ensure not only a beautiful aesthetic effect, but also a very high cutting capacity, penetration and edge retention along with easy resharpening and maintenance. At the same time, the blade has remarkable corrosion resistance and an important increase in resilience given by the type of extreme steel and laminated 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 2022 collaboration, between the Collini Cutlery of Busto Arsizio and the Fox of Maniago, we have decided to propose the 103MB Outdoor model designed by Reichart Markus. Only 18 exclusive pieces of this excellent bushcraft knife produced by Fox of Maniago were made, using for this edition the Japanese V-Toku2 steel in Sanmai 5mm produced by the Japanese Takefu Steel instead of the Niolox used in the series 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, in addition to a beautiful aesthetic effect, a very high cutting capacity, penetration and sealing of the wire together with an ease of re-sharpening and maintenance. 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.

Knife withdrawn from a private collection - Limited edition production in Japanese CoS steel in SanMai dating back to 2018 and no longer available - In like new condition, no marks on the blade (never cut, never resharpened) or on the handle. Supplied with handmade Kydex sheath and Wander Tactical certificate - Checked and certified by our in-house Coltelleria Collini laboratory.

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.

Notes: Opening by Carson Flipper system - Movement on ball bearings - Design by Jesper Voxnaes - Exclusive version by Coltelleria Collini, Sprint Run in only 6 not numbered pieces, with Japanese stainless steel Takefu Steel SPG2 Rolled.

The rolled steel - imported in 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. As early as 1100, expert Japanese blacksmiths combined different materials to give Katana swords incredible cutting capabilities combined with previously unknown strength and flexibility. It is thanks to this revolutionary construction technique that the Samurai swords have been preserved until our days 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 by famous brands such as Fallkniven, Cold Steel, Mcusta, Kai, Sog, Zwilling, Rockstead, etc.

- Longer cutting edge life
thanks to the use of high quality steels with high carbon content (VG10, CoS, Shiro) or sintered (SPG2), in the core steel, the blade, once hardened, reaches hardness and cutting performances definitely higher than those reached with the use of traditional steels.

- Greater resilience
Built on the principle of Japanese swords, the 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).

- Improved corrosion resistance
The steel used for the outer layers (Stainless Steel) gives the blade a high resistance to corrosion. The combination of the two or more materials used by Takefu Steel generates, at a galvanic level, a structure that improves corrosion resistance even on the edge.

- Easy machining even after heat treatment
Although steel normally becomes harder after hardening, the lateral steel used in multilayer machining does not lose its softness and allows easy machining, drilling or welding even after heat treatment. For optimum blade performance, cryogenic treatment is recommended.

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

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.

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 the 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 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.

Col Moschin model: for this First Production Run a run of 11 pieces was produced, numbered from 1 to 11.

Special purpose cutting knife, specially developed for the 9th Col Moschin Parachute Assault Regiment, elite unit of the Folgore brigade.

Use: tactical, sports, hiking, collection

Blade: integral, in laminated Japanese steel (San Mai) with V-Toku2 (carbonaceous) cutting edge at 62 / 63HRC and external SUS410 (stainless steel) scales
Handle: forprene
Blade length: 160mm.
Blade thickness: 6.5mm.
Total length: 290mm.
Balance: set back to 0.5cm. from the guard branch
Weight: 265g.
Sheath: modular tactical, from thigh or belt, in Nylon
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.

Rolled steel - imported into Italy by Collini Steel directly from 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 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, 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 damascus pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.
