    Folding knife made according to specifications requested by the Italian Army unit 185th RAO (Regiment for Target Acquisition) and currently in service with the same unit. The service version differs from the civilian one only by the complete absence of writings or logos on the blade.

    HISTORICAL NOTES ON THE UNIT:
    The 185th RAO of the "Folgore" is a unit with ancient traditions, yet relatively new in its current form. It was established on 3 April 2000 following the reorganization of the 185th Paratroopers Artillery Regiment. Based in Livorno, it is an atypical artillery unit currently included within the Special Forces framework.

    Composed entirely of volunteer personnel, the 185th RAO selects its members through physical tests and a qualification course structured in modules of increasing difficulty. The tasks assigned to RAO operators are numerous and highly sensitive: they involve gathering information on enemy targets and relaying it to command. More generally, this can be described as reconnaissance in sensitive areas.

    "It is therefore clear," the Army emphasizes, "that the activity of the acquisition operator takes place mainly in hostile territory, in small self-sufficient teams operating in isolation."

    RAO paratroopers are specialists in infiltration and exfiltration techniques and are able to operate in the field for up to 8–10 days without external resupply. They know how to avoid capture, escape and evade from enemy-controlled areas and, above all, how to identify, define and assess strategically relevant targets. Since 2002, the year of its reorganization, detachments of the 185th Regiment have operated in all major operational theaters: from the Balkans to Afghanistan and Iraq. In these areas they mainly carry out medium- and long-range reconnaissance and surveillance activities within the area of responsibility of the Italian contingent.

  2. ExtremaRatio - Fulcrum Bayonet EVO NFG - Stonewashed N690Co & Desert Forprene - Multi-purpose Knife

    Following the success of the FULCRUM multi-purpose knife, the bayonet version was developed, designed for even more specific and demanding applications. Like the FULCRUM, the bayonet is an extremely robust and versatile knife: the blade withstands breaking loads exceeding 150 kg, the tip is extremely durable, and the profile allows for extended use without compromising the sharpness of the cutting edge. The forward-shifted center of gravity, combined with the blade’s weight, ensures excellent performance in the most demanding fieldwork, offering power and control even under the toughest conditions.

    The 2026 EVO model introduces a major design update: the knife’s tang now features a completely redesigned structure, engineered to improve structural rigidity and optimize stress management during the most intense use, while also offering a more precise and secure feel during technical tasks.

    This specific civilian NFG (No Fixing Gear) version retains the same operational structure but lacks the rifle attachment mechanisms, making it more streamlined, lightweight, and geared toward professional outdoor use.


    Intended Use: Multi-purpose / Utility / Tactical

    Production Type: Industrial
    Country of Manufacture: Italy
    Blade: hidden tang in N690Co stainless steel, 58 HRC
    Blade finish: Stonewashed
    Handle: detachable, made of Forprene, with a full-tang guard and stainless steel tang.
    Blade length: 180 mm.
    Blade thickness: 6.3 mm.
    Overall length: 309 mm.
    Weight: 391 g.
    Sheath: modular tactical nylon thigh sheath with polymer interior, equipped with a wire cutter and diamond-coated plate for field sharpening
    Packaging: Cardboard box with Extrema Ratio logos
    Notes: Civilian version without weapon attachment systems, making the Fulcrum EVO Bayonet a standard knife available for free sale and legal possession

  5. ExtremaRatio - Selvans - S600 Black - Heavy Utility Survival Knife - knife

    The Selvans S600 Black is a survival knife with total black design, made of Böhler S600 steel with hardness of 64 HRC. Powered by the excellent properties of this steel, it is designed to cope with extreme environments and outdoor operations such as cutting branches and building shelters.

Böhler S600 steel, used in industrial tools, offers wear resistance and holds the edge for a long time thanks to cryogenic treatment and 64 HRC hardness. The EXP DARK coating protects the blade from oxidation, while the Cordura thigh sheath with MOLLE system allows for convenient carrying.

  6. ExtremaRatio - Fulcrum Black - N690Co & Forprene - knife

    The FULCRUM is a milestone among multi-role knives.

  7. ExtremaRatio - Selvans Expeditions - Heavy Utility Survival Knife - knife

The handle has been lengthened and the blade weighted to promote effective cutting strokes. It comes with a desert Cordura sheath with MOLLE system, equipped with a mini pouch containing paracord with flammable filament that can be used in case of emergency and/or critical weather conditions and a Firesteel for lighting fires.

  8. 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.

  9. ExtremaRatio - SERE 2 - GOI Gruppo Operativo Incursori - rescue knife

    S.E.R.E. 2, adopted by the Operational Group of Italian Navy Incursors, is the development of the S.E.R.E. 1, created by a study group composed of Special Forces operators, martial artists and experts in survival techniques. This variant 2 has been revised according to the needs expressed by the Department.

    The acronym S.E.R.E. refers to the four principles "Survival, Evasion, Resistance and Escape" which make up the training program provided to military personnel at high risk of capture.

    The S.E.R.E. 2 is suitable for both tip and cut use. The unique grip, unlike the classic blades of this type, is fixed between the index and the middle, thus forming a single axis from the tip of the blade to the user's wrist, allowing its use also in reverse grip. The handle has the same ergonomics as the butt of a firearm; this grip allows an instinctive and immediate use, being able to easily integrate the training in the training activity.

    The geometry of the tip ensures maximum penetration, at the same time its axial profile with a triangular base protects its resistance. The design of the blade has on one side a partially serrated profile to favor the cutting of cordages, and on the other hand a classic cut or straps that, unlike the previous model, has re-sharpening and interchangeable blades.

    The central loop, which has the dual function of lightening and turn-crickets, recalls the maritime origins of its creators. The peculiarity of the knife is that it has been specifically designed to be used even without the handle; the two holes in the part dedicated to the handle facilitate assembly.

    The kydex sheath has a basic retention that can be used alone for operators who need extremely fast knife use, and a removable locking lock if necessary. The knife is supplied with double safety for ambidextrous mounting. An insert with a flat-blade screwdriver is available as an accessory. Comes with belt clip for belt fastening and paracord for fixing on the M.O.L.L.E. system.

    "Using the gun, knife or other weapon for us is the same thing: it's just the extension of the hand." Quote from a commander of the ward.

  23. ExtremaRatio - 185° RAO - 2018 Version - heavy folding knife

    Folding knife made to specific requests of the Italian Army department 185 ° RAO (Regiment Acquisition Objectives) and currently supplied to the homonymous department. The supplied knife differs from the civil one only because of the total lack of writing or logos on the blade.

    HISTORICAL SUMS ON THE DEPARTMENT:
    The 185 ° RAO of the '' Folgore '' is a department with an ancient tradition, but very new. In fact, it was born on April 3, 2000 following the reconfiguration of the 185th terrestrial paratroop artillery regiment. Based in Livorno, it is an atypical department of the artillery weapon, currently inserted in the Special Forces basin.

    Entirely composed of voluntary personnel, the 185th RAO selects its components through the passing of a physical test and a qualification course on modules '' with increasing difficulty ''. The tasks entrusted to the RAO's men are many, but all very delicate: it is about gathering information on enemy objectives and 'passing them' to one's command. More generally, it can talk about '' recognition in sensitive areas ''. '' It is therefore evident - they stress to the Army - that the activity of the acquirer takes place mainly in hostile territory, in small self-sufficient nuclei that act in isolation ''.

    RAO paratroopers are specialists in '' infiltration and exfiltration '' techniques and are able to move in the operating area '' for up to 8-10 days without external supplies ''. They know how to 'escape from capture, escape and escape from an' enemy controlled area '' and, above all, as '' identify, determine and evaluate objectives '' of strategic interest. Since 2002, the year of reconfiguration, the 185th Regiment detachments have operated in all the hottest operational theaters: from the Balkans to Afghanistan, to Iraq. Here they mainly carry out surveys for medium and long-range information purposes and for monitoring the area of ​​responsibility of the Italian contingent.

  32. ExtremaRatio - KH Satin - Kukri Machete - knife

    A well-motivated classic. The "kukri," the Nepalese multi-purpose tool made famous by Rgt. Gurka, in the service of His Britannic Majesty and derived from ancient Greek falcate swords.

    The blade of this machete has differentiated roundings. Near the handle the blade is razor rounded so that a narrow sharpening angle can be achieved without unduly affecting the thickness of the back material, which must remain solid. The rounding at the end of the blade, on the other hand, is flat and well angled so as to effortlessly penetrate wood and vegetation.

    Usually these kinds of tools are made of soft steel to be more elastic and more easily resharpened. Extrema Ratio has succeeded in obtaining an elastic tool with a decidedly long-lived and durable sharpening by using instead a hard steel such as BÖHLER N690. This machete comes with a thigh scabbard with black Cordura storage pocket and safety carry strap.

    Intended Use: Tactical/Military

    Blade: N690Co 58HRC stainless steel
    Handle: Kraton
    Blade length: 340mm.
    Blade thickness: 6.3mm.

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.
