  4. ExtremaRatio - Satre Expeditions - Utility Neck Knife - Knife

    Satre Expeditions, as well as the Satre model from which it derives, is a fixed blade knife of small dimensions, light and extremely resistant. Given its characteristics, it can be used in a wide range of disciplines and uses or as part of an EDC (Every Day Carry) kit.

    It has been designed in collaboration with Daniele Dal Canto, Master Advanced F.I.S.S. (Federazione italiana survival sportivo e sperimentale) instructor. In Neck Knife mode, through the use of a 550 paracord lanyard, it is possible to hold it around the neck keeping the knife vertical with the handle facing downwards.

    The metal eyelets on the sheath, made of pre-shaped Kydex, allow the application of both the lanyard and the accessory holder. 

    The full-tang skeletonized structure, allows you to customize the knife using Paracord as a coating for the handle.

    Satre Expeditions uses Böhler N690 steel heat treated to 58 HRC with MIL-C-13924 burnishing and stone washed surface treatment (Dark Stone finish). It comes with a desert-colored pre-formed kydex sheath on which you can attach the Firesteel for lighting fires (provided inside the box).

  5. ExtremaRatio - Sethlans Expeditions - Survival Knife - knife

    Sethlans Expeditions, as well as the Sethlans model from which it derives, is a fixed blade work knife designed to deal with a wide range of situations, but also as a backup blade. The Sethlans Expeditions has been designed in collaboration with Daniele Dal Canto, Master Advanced F.I.S.S. (Federazione italiana survival sportivo e sperimentale) instructor.

    Sethlans Expeditions has a Böhler N690 steel blade heat treated to 58 HRC with MIL-C-13924 burnishing and stone washed surface treatment (Dark Stone finish). The knife comes with desert colored G10 grips that feature the ergonomic design characteristic of Extrema Ratio handles. They can be removed to free the skeleton structure of the knife, allowing maximum lightness with minimum thickness.

    For lovers of extreme customization, the full-tang structure allows the handle to be covered with paracord. The sheath is composed of a very light and minimalist Kydex part. It can be disassembled and can be adapted to both left- and right-handed people. The addition of an optional belt clip allows both vertical and horizontal positioning of the knife and makes the sheath much more versatile than the textile version. It is equipped with a mini pouch with M.O.L.L.E. system containing paracord with flammable filament to be used in case of emergency and/or critical weather conditions and a Firesteel for lighting fires.

  7. ExtremaRatio - Kreios Expeditions - Heavy Utility Machete - Knife

    Kreios Expeditions, as well as the Kreios model from which it derives, has been designed and developed thanks to the collaboration with the Master instructor F.I.S.S. (Federazione Italiana Survival Sportivo e Sperimentale) Daniele Dal Canto. It is defined by its creator as a sort of "off the road" of cutting tools, therefore not a specific disposable tool, but a multi-tasking tool, extremely versatile and designed to cope with many uses.

    Thanks to its ergonomics, weight and size, Kreios Expeditions is suitable to open gaps in the thick vegetation, especially where it is necessary to take distance, for safety reasons, from thorny or harmful essences. Thanks to its robustness, it is an effective machete even in the heaviest field work. Combining the 32 cm of the "full flat" cutting edge, the 11° forward inclination of the blade and the 630 gr. of its weight, you get a tool with extraordinary cutting capabilities that does not fear bending.

    Kreios Expeditions brings modern geometry and materials combined with the lines and effectiveness of blades typical of the Malaysian and African tradition, creating an ideal tool for field work but also, if necessary, for defense/offense. Kreios Expeditions is equipped with a desert color forprene handle and a BÖHLER N690 (58HRC) steel blade with MIL-C-13924 burnishing and stone washed surface finish (Dark Stone finish). It is supplied with a desert Cordura sheath with MOLLE system and strap for safety carry, equipped with a mini pouch containing paracord with flammable filament to be used in case of emergency and/or critical weather conditions and a Firesteel for lighting fires.

  8. 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.

  10. ExtremaRatio - Satre - S600 Black EXP Dark - Neck Knife

    Satre is a fixed blade knife of small dimensions, light and extremely resistant. Given its characteristics, it can be used in a wide range of disciplines and uses ranging from survival activities, bushcraft or as an element of an EDC (Every Day Carry) kit.

    It has been designed in collaboration with Daniele Dal Canto, Master Advanced F.I.S.S. (Federazione italiana survival sportivo e sperimentale) instructor.

    In Neck Knife mode, through the use of a 550 paracord lanyard, it is possible to hold it around the neck keeping the knife vertical with the handle facing downwards. The metal eyelets on the sheath, made of pre-shaped Kydex, allow the application of both the lanyard and the accessory holder.

    The full-tang skeleton structure allows to personalize the knife using the Paracord as a coating for the handle.

    The Black S600 version uses Böhler S600 steel. This steel is used in industrial manufacturing to make metalworking tools and in mold making.

    The high content of Molybdenum, Tungsten and a good presence of Vanadium in its chemical composition, give it excellent qualities of hardness, wear resistance and toughness. The presence of Cobalt favors the formation of small carbides uniformly distributed, a characteristic that enhances and elevates wear resistance.

    Satre S600 is hardened and cryogenically treated, thus reaching an exceptional hardness of 64 HRC. This gives it great wear resistance and the ability to guarantee the cutting edge of the wire for a long time.

    Böhler S600 has 4.5% Chromium, which makes it a carbon steel and therefore can cause rust and oxidation if neglected. To better protect it from atmospheric agents, we have chosen the new external coating EXP DARK.

    The high hardness and resistance to wear and abrasion, make this steel not easy to sharpen.

     

    Intended Use: Neck Knife / Hiking / Utility

    Production type: industrial
    Country of production: Italy

  15. ExtremaRatio - N.K.1 Neck Knife - SanMai V-TOKU2 - Limited Edition - NK1 - Knife

    Japanese steel merges with Italian excellence

    For this 2021 collaboration, exclusive to Coltelleria Collini, 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 have used the carbonaceous V-Toku2 at 62/63HRC for the central plate and the stainless SUS410 for the two external plates, in order to guarantee a very high cutting capacity, penetration and edge holding together with an easy resharpening and maintenance but at the same time the blade has a remarkable resistance to corrosion and an important increase of resilience given by the type of extreme steel and the laminated structure.

     

    Intended Use: Neck Knife / Collector's Knife

    Type of production: Industrial
    Country of Production: Italy
    Blade / Handle: Full, laminated Japanese steel (San Mai) with V-Toku2 (carbonaceous) cutting edge at 62/63HRC and SUS410 (stainless steel) outer cheeks
    Blade finish: Satin finish
    Blade length: 40mm.
    Blade thickness: 3mm.
    Total length: 129mm.
    Weight: 55g.
    Sheath: Kydex, for neck.
    Packaging: Cardboard box with Extrema Ratio logos.
    Notes: Numbered edition - cardboard box with Extremaratio logos and certificate - the central core of the blade and handle is made of carbon steel so it is recommended to wash/dry the knife very well after each use and protect the steel, during storage, with a light surface of lubricant to avoid rust and oxidation.

     

     

    As in the ancient swords of the Japanese Samurai.

    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 also by famous brands such as Fallkniven, Cold Steel, Mcusta, Kai, Sog, Zwilling, Rockstead, etc.

    Characteristics of San Mai steel: It is made of different types of metals alloyed together to create a composite that contains and intensifies the strengths of the metals individually taken:

    - Longer cutting edge life
    thanks to the use of high quality steels with a high carbon content (VG10, CoS, Shiro) or sintered (SPG2), in the core steel, the blade, once hardened, reaches hardness and cutting performance decidedly superior to those achieved 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.

  18. ExtremaRatio - Herring NE - Fairbairn Sykes Dagger - tactical knife

    The Herring dagger is one of the most loved military knives by enthusiasts.

    Its original name is Fairbairn Sykes or Commando Dagger and it was present in the endowment of the British Commandos.

    A dagger that entered Italian history in World War II, thanks to the exploits of young soldiers of the 1st "Folgore" Reconnaissance Squadron, who were equipped with this weapon during Operation Herring. He has behind him a heroic piece of history that is rarely talked about, despite the fact that these young boys, thanks to their devotion to the cause and their courage, have written an important page in Italian history.

    Extrema Ratio wanted to pay homage to this dagger trying to remain faithful to the original forms, while using the most modern production techniques.

    The very special hand-made finish of the handle simulates the aging of brass and gives the dagger a dated look, similar to the original.

    The dagger was developed in collaboration with the 185th RAO and adopted as a ceremonial commemorative dagger for the 20th anniversary of the regiment's establishment and the 75th anniversary of the Herring mission.

    The knife is equipped with a polymer case with historical frieze of the F Squadron, leather / kydex sheath with brass tip and two commemorative scrolls.

    PLEASE NOTE:
    NE version, simulacrum replica with rounded tip and blunt blade, to allow free sale and possession according to the current regulations in force on the Italian territory.

    We warn that any subsequent modifications and sharpening made to the blade modify the status of simulacrum of the Herring NE. In this case it will be subject to the regulations in force in the respective countries. Furthermore, these changes will void the Extrema Ratio warranty.

  19. ExtremaRatio - Sethlans Survival - N690 Stone Washed - Knife

    The "Extrema Ratio Sethlans" is a fixed blade work knife created to face a wide range of situations, suitable for survival, bushcraft, prepping, but also as a backup blade. The Sethlans is available in two versions with two different types of steel.

    Stone Washed version that uses Böhler N690 heat treated at 58 HRC, chosen for the reliability it has shown over the last 20 years due to its resistance to oxidation and durability of the wire.

    The knife comes with G10 grips that feature the ergonomic design characteristic of Extrema Ratio handles. They can be removed by releasing the skeletonized structure of the knife, which allows maximum lightness with minimum thickness. For lovers of extreme customization, the full-tang structure allows the handle to be covered with a paracord cord.

    The sheath is composed of a part in very light and minimalist Kydex. It can be disassembled and can be adapted for both left and right handed users. The addition of an optional belt clip allows the knife to be positioned both vertically and horizontally and makes the sheath much more versatile than the textile version. It is also equipped with a mini pouch with M.O.L.L.E. system. containing a double-sided stone for sharpening and a firesteel for lighting fires.

  20. ExtremaRatio - Misericordia - 4th Alpine Paratroopers Regiment - tactical knife

    The Extrema Ratio Misericordia was adopted by the 4th Alpine Paratroopers Regiment which helped develop and test the product. It is a tactical fixed blade knife, extremely light and compact, it can be used both as a main knife or as a backup blade.

    The blade is made of Böhler N690 steel, heat-treated to a hardness of 58 HRc, it is 118 mm long, 4mm thick and has a flat edge.

    The profile is of the spear point type, with a full length fuller which makes the blade even lighter and with a false counter-thread at ¾ length. The blade is available with the classic Extrema Ratio MIL-C-13924 black finish.

    The handle in fiberglass-reinforced nylon (FRN) features the classic Extrema Ratio recesses that make the grip safer and is fixed to the tang by means of a through screw.

    On the rear end the handle flows connecting with a large ring, which allows the use of martial arts techniques and ensures a very solid grip to the hand, equipped with a "skull crusher" appendix in hard metal.

    The overall weight of the knife is just 87g. Being a knife designed for professional use, much attention has been paid to ease of port, accessibility and extraction in case of need. The knife is secured to the sheath by a quick-release safety catch that can be easily reversed for use by left-handers.

    The sheath is made of highly resistant Nylon, it is very versatile and two adjustable loops allow it to be fixed inside the loops of M.O.L.L.E.

    The sheath is equipped with a conical invitation to facilitate the re-insertion of the knife while a simple pressure on the trigger safety allows it to be extracted quickly and instinctively.

  25. 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.

    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.
