  1. ExtremaRatio - G.O.I. Caimano Nero N.A. Flipper - Knife

    NON-automatic version of the Caimano Nero model

    The Black Caiman is a tactical knife that Extrema Ratio, official supplier of Comsubin, has developed and delivered to the G.O.I. (Gruppo Operativo Incursori) of the Italian Navy. Its name recalls and pays homage to the heroic Caimani Neri del Piave, a department of Arditi of the Regia Marina and other components on a voluntary basis, which during the First World War crossed the Piave River by swimming to carry out raids in enemy territory.

    Spear Point" 4 mm blade with asymmetrical rounding and partial sharpening of the counterbore to increase the penetration coefficient. The toothing on the blade allows you to cut cables and fabrics with high resistance preserving the sharpness.

    It is a medium folder with a robust structure. The thick aluminum cheeks, thanks to the many processes of removal make the knife light and balanced. The end of the handle, which recalls the shape of the Helix/Timon group of the slow running torpedo (S.L.C.), serves to improve the grip for the rapid extraction of the knife from the pocket.

    The DLC-coated titanium clip can be positioned at three different angles on either side to allow for maximum customization of the carry. Its shape is designed to minimize the bulk of the handle outside the pocket.

    Among its endowments, besides the carbide glass breaker, there is also a safety, that when inserted, preserves from a dangerous accidental closing of the blade.

  7. ExtremaRatio - T911 Tuscania Rescue Tool - folding knife

    On December 19, 1941, in Eluet El Asel, about 400 men from the 1st Royal Carabinieri Battalion Paratrooper faced the assault of 4 battalions of Indian troops of the British Army. Jumping from their trenches by launching improvised devices, the "Desert Lions", as Radio London called them, made the defensive line impenetrable by allowing thousands of Italian-German troops to withdraw safely. This was the first page in the long history of Italian paratroopers.

    The Tuscania Paratrooper Regiment asked that the Extra Ratio T911 be specifically made as a commemorative knife for its 80th anniversary.

    The T911 is a medium-sized folding light and designed for professional use by military operators. It is equipped with a modified spear point blade, flat edge, in Bohler N690 cobalt steel heat-treated to a hardness of 58 HRC, for the best compromise between strength, ease of regrinding and thread hold. The blade is 76 mm long, 4 mm thick, has a stone washed finish and rotates around an adjustable pin which allows to obtain the best fluidity in opening. A brace allows you to lock the pin in the best position.

    The handle is in Anticorodal aluminum alloy with high strength black anodized finish and is milled to facilitate the transition from "reverse grip" handle to saber handle.

    The blade is opened by means of a pin operated with the thumb. The knife uses a liner lock type blade lock and a safe ensures maximum hold even during heavy use. The safety lever is colored red for better visibility and engages in an advanced position for more instinctive use.

    In the handle are integrated a seat belt cutter with easily available and replaceable cutter-type blade, a tungsten glass breaker, a stainless steel knot loosener and a screwdriver for adjusting the pointing optics, in AISI 420 steel. The clip , reversible and fixed at the end of the handle, allows a very deep port in the pocket, for less visibility.

    The knife can be dismantled for cleaning and maintenance. With a total length of 194 mm and a weight of 145g, the T911 is easy to wear both in uniform and in civilian clothes.

    Note: -

    Extrema Ratio developed the first knife of a new production line, called CONTACT.

    It has a blade with a lance-shaped profile, a flat grinding and a diamond-shaped geometry. It has got a lower guard branch to protect itself from incidental cuts, upper jumping to improve grip, concave fuller along the length of the blade and a generous thickness blade (6.30mm) the now famous Requiem, revisited in proportions and in some technical features. The first of a new line of multipurpose knives.

    The blade is made in Böhler N690 steel with a hardness of 58 HRC and a chemical burnishing coating for the Black version. All other colors in production have got a blade with Stone Washed finishing. The handle is still in forprene. It is more assembled by the side screws but thanks to the shank in truncated cone-shaped stainless steel that is screwed to the bottom and goes to fit inside a special seat, which makes it solid. In this way the knife is well balanced. The sheath is minimalist; most of the fabric has been cut off; it has got a 2nd level retention system, remembering the style of the model it was inspired by.

    The main shell is injection-molded in shockproof nylon. The secondary retention system is reversible for ambidextrous users. The blade is guided through the conception of the blade. To extract the blade, to pressure the trigger will be sufficient, thus releasing the safety that holds securely in the sheath. In the horizontal slits of the sheath of a system, which fixes the blade to avoid shaking noises when it is stored inside. The back side of the nylon sheath is M.O.L.L.E. compatible.

    The textile part is reduced to its minimum and has got the classic two-button safety strap with a belt loop Extrema Ratio aims to reduce the size of the knife, but not saving on the structural strength and safety accessories.

    so be used as glass breakers

  23. ExtremaRatio - E.C.M. Cobra - ECM Einsatzkommando - Knife

    The Extreme Ratio E.C.M. (Einsatzkommando Cobra Messer) is a fixed blade multipurpose knife, designed for operational uses for the famous Einsatzkommando "Cobra" special unit of the Austrian police, whose logo is laser engraved on the heel of the blade. The Extreme Ratio E.C.M. it combines the characteristics of a practical tool and those of a reliable weapon, in a compact configuration with a total weight of 240g.

    The blade is made of Böhler N690 steel, hardened to 58 HRC and is 116 mm long, 5 mm thick and equipped with a flat edge. The profile of the blade is of the modified spear point type, with a false counter-thread ¾ in length on the back and a lower guard to protect the hand during use.

    Both the guard and the knob have holes to facilitate the attachment of the knife to various tools or for the passage of laces. The blade has a Carbon-based DLC (Diamond-Like Carbon) surface coating making it hyper-resistant to abrasion and chemical aggression.

    Given the heavy use of the tool, for the handle, instead of the usual Forprene, the more performing high-strength G10 is used.

  26. ExtremaRatio - Fulcrum C Satin knife in San Mai V-TOKU2 - Limited Edition - knife

    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.
    Blade length: 90 mm.
    Total length: 210 mm.
    Balancing: set back to 0.5cm. from the guard branch
    Weight: 210g.
    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.

    SILENTE is the name of the knife taken from the motto "SICUT NOX SILENTES" by N.O.C.S. Central Security Operations Unit, special anti-terrorist unit of the State Police.

    SILENTE was presented to the Department, the Authorities, the Minister of the Interior and the Chief of Police on the occasion of the forty-year ceremony of the foundation of the NOCS.

    SILENTE is a unique model of its kind that fulfills equally unique needs: the handle is divided into two parts and creates the handle of a clamp placed in the end of the handle. With it, in addition to taking on everything that has the appropriate dimensions, it is possible to cut wire, wire, steel cables, etc. and last but not least, it can be used as a window breaker, given the tungsten carbide insert at the end.

    The sheath protects the cutting edge during all these uses, allowing it to be used safely, but it can also release the blade with a fast and silent retention system. Adaptable to thigh use and applicable to the M.O.L.L.E system, it is integrated into the operator's equipment using the least possible space.

    ABOUT THE STEEL

    More than just a damask, Coreless steel made by Japanese Takefu Steel comes with over 70 layers of VG10 and VG2 stainless steel welded, forged and coated between them so that you can form a lightweight, slim and durable blade with a spectacular damask outer pattern.

    The peculiarity of Coreless steel, unlike conventional rolled steel or Japanese San-Mai, is that it does not have a hard core steel that is used for the cutting edge but has both the VG10 and VG2 steels arranged to form the cutting edge so alternating and sequential to each other.

    This particular construction gives the blade - compared to the two steels that make it, individually taken - greater resistance to oxidation, higher surface hardness (up to 61.5HRC), 25% more than cutting capacity, 25% more than the wire hold capacity and 25% more resilience making the blade more robust and less subject to breakage.

    Thanks to this latest steel, Takefu Steel has been rewarded on Japanese territory for research and development and innovation in the cutting-edge landscape. Coreless steel has already been chosen by major brands such as Kai and Mcusta Zanmai who since 2017 proposed it on their top productions of professional kitchen knives.
