  3. ExtremaRatio - Ant Black Knife - N690 - 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 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 Black version utilizes Böhler N690, hardened to 58 HRC for the best balance between edge retention and toughness, a type of steel used by Extrema Ratio for most of its knives.

    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 stainless steel N690 58 HRC

  8. ExtremaRatio - RAO C - N690Co & Aluminum Tactical Grey - folding knife

    Thanks to its structure, RAO C is a tool that despite its small size, manages to guarantee the same qualities of robustness and reliability as its big brother while offering better portability and manageability.

    The locking mechanism on opening is particularly strong as it is assisted by a safety system that turns it into a true fixed blade. The primary safety on the blade is activated by raising and lowering the locking pin. To provide the user with maximum safety in use, a practical and quick secondary safety has been applied, which can be activated simply by moving the locking pin horizontally.

    For the purpose of lightening the steel frames, a template was laser-cut from the profile of the RAO C, which was then used to make a gadget that is delivered with the knife.

  10. ExtremaRatio - Ferrum T knife - Black Warfare - knife

    Ferrum T is a folding knife with a clear tactical connotation equipped with a spear point blade with lightening slot. It has a slim and compact shape, the two anodized anticorodal aluminum grips make up a light, slender and at the same time very resistant handle. It can be housed in a breast pocket, in small flashlight holsters or inside a single loop of the M.O.L.L.E. system.

    Equipped with a flipper assisted opening system, the blade rotates on ball bearings which allow a smooth and uncertain movement of the blade.

  12. ExtremaRatio - Ferrum Rescue multi tool - Black - knife

    Ferrum Rescue is a tool designed for rescue operations, developed in collaboration with my friend Andrea Micheli, military and law enforcement expert, journalist and shooting instructor. Made with a very compact handle, this rescue tool is equipped with 3 blades, each of which has a specific function:

    The first and main blade has a thickness of 3 millimeters and is designed to be used for more demanding purposes and to protect the cutting edge of the other two from premature wear. The teeth allow it to cut larger ropes or textile materials, the remaining smooth part has the classic function of a knife. The second blade is a scalpel, which can be used for extremely precise cuts and for emergency first aid interventions. The third blade, on the back of the first, is the smallest of the 3, it has the function of cutting lines, capable of cutting paracord and aramid material.

    The interaction of the main blade with the scalpel allows the operator to make a quick emergency cut to free any injured person from his or her clothing.

    The line cutter blade and the scalpel are both interchangeable.

    Ferrum Rescue has a slim and compact shape, the two anodized anticorodal aluminum grips make up a light, slender and at the same time very resistant handle. It can be housed in a breast pocket, in small flashlight holsters or inside a single loop of the M.O.L.L.E. system. On the back there is also a hard metal glass breaker.

  20. ExtremaRatio - S-Thil Stone Washed - knife

    Extrema Ratio S-THIL STONE WASHED is a tactical backup knife with monolithic construction machined from a single piece of 5 mm thick BOHLER N690 steel, developed in collaboration with Thilo designer Arnd Schiller.

    The blade, a spear point type, is hardened to 58 HRC in order to achieve the best balance of edge retention and strength, features a false counterbore at the top that enhances penetration and point work characteristics, and has a full-length groove (fuller) that flows elegantly from the blade to the handle. The blade is milled integrally to the knife to enhance its compactness and lightness, maintaining a minimal thickness while still having a profile reminiscent of the classic Extrema Ratio handle.

    That profile goes to form two small guards and a comfortable thumb rest to prevent the hand from slipping towards the blade. On the end are a skull crusher with a diamond-shaped tip and a slot that allows a wrist strap to be attached to the knife or the handle to be fitted with paracord coiling.

    The molded nylon sheath is designed to be extremely flat with very small side dimensions to make it as compact as possible. The design of the knife makes it ambidextrous, allowing it to be inserted into the sheath with the blade cutting edge to the right or left. The double retention system integral to the sheath consists of four pressure elements that work only two at a time, depending on right/left-handed use, while the nylon textile part has a button that allows the knife to be secured to the sheath.

    The end of the sheath has a hole to expel liquids or debris inside. The ability to attach belt clip, ulticlip, malice clip makes it extremely versatile. You can also attach the sheath to the M.O.L.L.E. system by braiding the paracord.


    Intended Use: Tactical/Multi-role

    Production type: Industrial

    Blade: stainless steel N690Co hardened to 58HRC

  21. 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.


    Intended Use: Tactical/Machete

    Type of production: Industrial
    Country of manufacture: Italy
    Blade: stainless steel N690Co at 58HRC
    Blade Treatment: Burnishing MIL-C-13924

  22. ExtremaRatio - K1 Dobermann knife - XXV Anniversary - Limited Edition

    This special edition in 250 pieces, proposed on the occasion of the 25th anniversary of the brand, maintains the shape of the original, but with materials and finishes corresponding to the current production.

    The K1 is equipped with a modified spear point profile blade, characterized by a tip that combines the 40° "tanto" profile with the more traditional European one, creating a sharp but very solid hybrid which, with the false false edge, makes it particularly effective in jab. The bevel is high, allowing for a very effective cutting angle.

    The blade is immediately recognizable by the fenestration at the heel, which allows for considerable lightening without compromising its strength. It is made of Böhler N690 steel, with heat treatments that bring its hardness to 58 HRC for the best combination of edge hold and resistance. The finish is satin with flat grinding.

    The handle, in anodized Anticorodal alloy, compared to the original presents the lightening on the sides that make the Extrema Ratio knives immediately distinguishable, but maintains the arched shape and the lateral "bellies" of the K1, offering an excellent grip both in the "saber" than in the "reverse" grip.

    The terminal part of the handle curves to form a sort of hook which allows particularly easy and rapid extraction from the scabbard, while the tang protrudes from it with a triangular cusp which acts as a glass breaker with a slot which allows the knife to be equipped of lasso.

    The leather scabbard faithfully reproduces the original while maintaining both the qualities of ease and speed of extraction. The carry can take place in an upside-down axillary position, horizontally on the belt or tactically on the thigh.

    The K1 equipment is completed with a polypropylene case ‌, complete leather sheath and underarm shoulder strap.

  23. ExtremaRatio - K-Talon Karambit - N690 Dark Stone Washed - Knife

    The K-Talon is a karambit with a particularly thin full tang structure that, including sheath and grips, reaches a thickness of only 10 mm. The curved, hooked blade is designed inspired by the shape of a claw. It is designed to achieve precise, deep cuts while simultaneously hooking, trapping and/or ripping.

    The back ring is designed to achieve a strong and secure grip in all conditions preventing the knife from sliding back and making it exceptionally difficult to disarm or turn against the user.

    The very thin Kydex sheath has a quick release and comes with paracord that allows it to be used as a neck knife or attached to MOLLE-system platforms.

  24. 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.

  26. 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.

  27. ExtremaRatio - Satre - N690 Black - Neck Knife - Knife

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

    It was designed in collaboration with Daniele Dal Canto, Master Advanced F.I.S.S.S. (Italian Federation of Sports and Experimental Survival).

    In Neck Knife mode, through the use of a paracord 550 cord, it is possible to keep it around the neck by keeping the knife vertically 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

    This Black version uses the Böhler N690 heat treated at 58 HRC. This material is chosen for its resistance to oxidation, the durability of the wire and above all the reliability it has shown over the years.

    Intended use: Neck / Hiking / Utility Knife

  28. 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.

  36. 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.

  37. ExtremaRatio - Sethlans Survival - D2 Exp Dark - 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.

    Black version that uses D2 steel, heat treated and cryogenically treated at 60 HRC, which has a high resharpening capacity even with makeshift tools. To give greater qualities of hardness and resistance, the blade is coated with the new Teflon-based product "EXP DARK", proposed by Extrema Ratio.

    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.

  39. 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.
