    Clip: removable and reversible in stainless steel
    Sheath: in cordura
    Notes: safety mechanism both on opening and closing

    Extrema Ratio foldables:
    Directly derived from military specifications, this openable was developed to replace a fixed blade in use.
    To achieve this result, very robust materials, high thicknesses and a solid and safe opening/closing system were used: the back lock.
    The knife is equipped with a manual safety which provides maximum safety in use and drastically reduces the risk of accidental closures.
    The safety, if inserted in the lock, prevents military or police operators from having the knife turned against them in the event of theft.
    Materials and processes:
    All the parts of the knife are machined from solid by high-precision numerical control machines while the assembly, adjustment and sharpening are carried out by hand.
    The blade is made of N690 cobalt stainless steel, a steel with very high characteristics of resistance to mechanical stress, cutting capacity, edge retention and corrosion resistance. The grinding is flat and the hardness is 58HRC.
    The grip scales are in Anticorodal, an aluminum alloy with high resistance to mechanical stress and oxidation.
    The tang, in hardened N690, is an effective emergency glass breaker. All screws, pins and clips are in burnished stainless steel. The blade, the lever and the tang are covered with Testudo treatment, very resistant to abrasion and oxidation. The grips are black anodized.

  6. 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.

  21. ExtremaRatio - Ant Rescue Red Stone Washed Knife - M390 - Folding Knife

    The Ant is the most compact among Extrema Ratio's folding knives. Despite its small size, this model features an extremely sturdy, durable, and reliable structure.

    The Ant Rescue, unlike other versions, has a cheek piece in red coloration that allows the operator to more easily locate the knife in case of a fall. This version is equipped with a specific serration that allows cutting ropes and even high-tensile aramid materials. Moreover, this model has a tapered tang that serves as an emergency screwdriver. The Ant Rescue has been developed according to the needs expressed by the "Italian Army Alpine Troops School".

    The handle is made of two different elements: the cheek piece crafted from anodized anticorodal aluminum and the hardened steel frame which also serves as the blade lock (Frame Lock System). This mechanism involves a part of the frame bending inward to firmly secure the blade in the open position, enhancing the user's safety during the knife's use.

    The tang features a hole for the insertion of a lanyard, and on the right side of the handle, there is a steel clip that allows for concealed carry in the pocket.

    The Ant is available in 4 versions with two different types of steel, both provided by Böhler, an Austrian company with which Extrema Ratio has been collaborating for over 20 years, using its highly esteemed materials for the production of its blades.

    For the Stone Washed M390 version, Extrema Ratio uses Böhler M390 steel, thermally treated to 61 HRC, which, thanks to a powder metallurgy production process, ensures cutting effectiveness, wear resistance, and oxidation resistance over time.

    The blade is sheep foot-shaped and has a small hole on the top part to facilitate opening. Its particular structure, with a straight edge, allows the user to comfortably rest their fingers on the back of the knife and use it with ease.

    Type of production: industrial
    Blade: in partially serrated stainless steel M390 61HRC
    Blade production: Italy
    Handle: anodized anticorodal aluminum and steel
    Blade length: 70mm.
