    The blade of the DOBERMANN IV S600, made from Böhler S600 steel, offers excellent hardness, wear resistance, and toughness, thanks to the high content of molybdenum, tungsten, and vanadium. The addition of cobalt promotes the formation of small carbides, further improving wear resistance. With a hardness of 64 HRC, it ensures long-lasting edge retention. The “EXP DARK” teflon coating protects the steel from oxidation.

  3. ExtremaRatio - Waki Black Machete Knife - Tactical Knife

    The product is an elaboration of the Japanese Wakizashi sword, a typical blade 30 to 60 centimeters long, which the Samurai carried at all times in contact with the body, where the Katana was carried exclusively in battle. The blade produced from Boehler N690 steel is hardened to 58HRC while the handle is made of forprene, an elastomer that falls under the "NATO standard" for resistance to extreme conditions. The Waki Black comes with a cordura, military-derived scabbard that ensures safe carrying of the razor-sharp blade and its protection from shocks that could reduce its efficiency. The scabbard is also equipped with the MOLLE system that allows it to be carried on tactical vests and general belts.

  4. 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.

  5. ExtremaRatio - DMP - Black - tactical knife

    DMP is a multi-role knife characterized by a strong versatility of use thanks to the small dimensions. The drop point blade with reinforced tip is particularly useful for heavy duty use. The full flat rounding gives excellent cutting characteristics.

    The sheath is minimalist, stripped of most of the fabric adopting a retention system of 2nd level, going to recall the style of the model to which it is inspired. The main shell is made by injection in shockproof nylon. The secondary retention system is reversible for the ambidextrous portability of the knife.

  9. 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.

  12. ExtremaRatio - Frame Rock Titan - Black DLC - folding knife

    The Extrema Ratio Frame Rock is a new knife, based on the Ti-Rock project, a successful frame-lock knife made by Extrema Ratio in 2016 exclusively for Coltelleria Collini.

    The Extreme Ratio Frame Rock is characterized by the titanium handle that offers great resistance while being very light. The integrity of the frame-lock locking system is guaranteed against wear by an easily replaceable hardened steel insert.

    Unlike its drop-point predecessor, the Rock frame has a spearpoint blade 75 mm long, 6.0 mm thick, equipped with fuller for further lightening. The blade is made of Bohler N690 steel, heat treated to a hardness of 58 HRC. The same is available in black finish with DLC or satin finish.

    To make the opening even more fluid and free of uncertainties, the blade rotates on ball bearings. This mechanism allows the user to adjust the force necessary to release the blade from the closed position.

    The shape of the reversible clip allows a hidden port in the pocket, making the knife not visible from the outside. The large, solid handle and the well-proportioned blade allow this knife to tackle demanding tasks. Frame Rock weighs less than 200g, making it somewhat light for such a sturdy knife. It is supplied inside an ABS box.

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.

    PESO: g 390
    LUNGHEZZA LAMA: mm 180
    LUNGHEZZA TOTALE: mm 308
    SPESSORE LAMA (PRINCIPALE): mm 6.3
    ACCIAIO DELLA LAMA: N690 (58HRC)
    MATERIALE IMPUGNATURA: NYLON
    DENTATURA PARZIALE: NO
    FINITURE E TRATTAMENTI: CAMO MIL-C-13924

    La rivisitazione di un classico, il tributo ad un veterano, il restyling di uno dei pugnali da guerra più largamente distribuiti ed impiegati nel secondo conflitto mondiale: il MARK 2.

    Prodotto dalle aziende storiche statunitensi, in innumerevoli varianti ma sempre fedele alle specifiche originali del contratto U.S.NAVY nella forma generale, questo pugnale rimane il preferito dei nostalgici e dei tradizionalisti che si affidano soltanto a strumenti “battle tested”.

    I produttori si sono spesso cimentati nell’impresa di modernizzare questo pugnale con risultati non incoraggianti tanto che il modello tradizionale occupa ancora una posizione di rilievo nei principali cataloghi.

    Extrema Ratio si cimenta in questo ambizioso progetto con l’obiettivo di mantenere le caratteristiche peculiari dell’originale per effettuare soltanto modifiche funzionali mirate all’incremento delle prestazioni.

    Acciaio inossidabile al cobalto per la lama, AISI 303 e AISI 304 per le altre componenti, nel manico il Nylon caricato con fibra di vetro ha preso il posto del cuoio a rondelle.

    L’ergonomia dell’originale è stata mantenuta ma tutte le parti strutturali sono state sovradimensionate per farne un massivo e performante coltello multiruolo.

    A livello concettuale, le modifiche più significative sono mirate a risolvere i tradizionali “punti deboli” del modello originale: la possibilità di effettuare lo smontaggio da campo senza utensili, la punta con profilo Bowie modificato dritto (più facile da riaffilare) e le scanalature sull’impugnatura “a botte”, che aiutano a percepire anche al buio il verso della lama e incrementano geometricamente la tenuta nei movimenti di torsione (effetto cacciavite).

    Altre piccole modifiche sono i fori per il laccio di sicurezza (di cui l’originale era sprovvisto) e i fori sulla guardia che permettono di legare il pugnale ad un bastone da usare come lancia da sopravvivenza.

    Il tradizionale scolasangue è stato “vigliaccamente” sostituito con il tipico “side groove” Extrema Ratio per motivi che confessiamo essere puramente estetici: a noi piace così…

    Il resto, effettivamente, andava bene com’era…e così lo abbiamo lasciato.

    Le prime due versioni sono il classico nero Extrema Ratio e il Desert Warfare, quest’ultimo alloggiato in un fodero coyote HCS specificatamente studiato per le SOF.

    Il fodero della versione nera è standard, con innesto automatico del coltello, pattella e cinghia cosciale per il fissaggio al fianco, compatibile con sistema MOLLE.

  60. 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.

  61. ExtremaRatio - Frame Rock Titan Knife - Blue Satin - PRIVATE COLLECTION - folding knife

    Knife withdrawn from a private collection - In like new condition - Never regrind - Checked and certified by our in-house Coltelleria Collini laboratory.

    The Extrema Ratio Frame Rock is a new knife, based on the Ti-Rock project, a successful frame-lock knife made by Extrema Ratio in 2016 exclusively for Coltelleria Collini.

    The Extreme Ratio Frame Rock is characterized by a titanium handle that offers great resistance while being very light. The integrity of the frame-lock system is guaranteed against wear by an easily replaceable hardened steel insert.

    Unlike its drop-point predecessor, the Rock frame has a 75mm long, 6.0mm thick spearpoint blade fitted with a fuller for further lightening. The blade is made of Bohler N690 steel, heat treated to a hardness of 58 HRC. The same is available with a black finish with DLC treatment or satin.

    To make opening even more fluid and without uncertainty, the blade rotates on ball bearings. This mechanism allows the user to adjust the force necessary to obtain the release of the blade from the closed position.

    The shape of the reversible clip allows a hidden port in the pocket, making the knife not visible from the outside. The large and solid handle and the well-proportioned blade allow this knife to tackle heavy tasks. The Frame Rock weighs less than 200g, making it somewhat light for such a sturdy knife. Comes inside an ABS box.

    Intended use: collection / CQD

    Type of production: industrial,
    Blade: N690Co stainless steel
    Blade treatment: Satin finish
    Country of production: Italy

  65. ExtremaRatio - Selvan Heavy Utility Survival Knife in San Mai V-TOKU2 - Limited Edition - knife

    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.
    Blade thickness: 6.3mm.
    Total length: 310mm.
    Thick when closed: -
    Balancing: advanced
    Weight: 424g.
    Sheath: nylon, MOLLE compatible
    Packaging: Cardboard box with Extrema Ratio logos
    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.

  66. ExtremaRatio - Task Desert Warfare - Tactical Knife

    The Task series has been designed for all everyday cutting jobs.

    The partially symmetrical blade with flat edge on both sides. The hollow part of the blade after the guard, which separates the sharp part from the handle, has been made to house the index finger during use, creating a grip point near the sharp part for better control while using the knife.

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.

    Blade thickness: 6.3 mm.
    Blade length: 90 mm.
    Total length: 210 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.
