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.

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.

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.

ExtremaRatio - Misericordia Desert - single edge fixed blade knife - Made in Italy
Extrema Ratio Misericordia Desert, which preserves intact all the features of the famous Misericordia model adopted by the 4th Alpine Parachute Regiment, derives from the commemorative dagger made on the occasion of the 140th anniversary of the 4th Alpine Regiment and the 70th since the founding of the Alpine Paratroopers.
It is a tactical-type fixed-blade knife designed for those instances when the knife must be extremely light and compact. The new desert coloring also makes this model available in a shade in line with the most common needs of modern operational departments.
The blade is milled from Böhler N690 steel, hardened to 58 HRC for the best balance of edge retention and strength, is 118 mm long, 4mm thick, and has a flat edge. The weight of the knife is just 87g. The profile is a spear point type, with a full-length shank that makes it even lighter and with a ¾-length false counterblade. The finish is a stone washed type.
The knife's polymer handle features classic Extrema Ratio shells that make for a more secure grip and is attached to the tang by a through-screw. On the rear end the handle flows connecting with a wide ring equipped with a "skull crusher" appendage: a ring that allows the use of martial arts techniques and ensures the hand a very solid grip. In this version the handle is in Desert coloring.
Since this is a knife designed for professional use, much attention has been paid to ease of carrying, accessibility and extraction in case of need. The knife is secured to the sheath by a quick-release safety that can be easily reversed for left-handed use. The sheath is also in Desert coloring, made of high-strength Nylon, very versatile and equipped with 2 adjustable loops that allow it to be attached to M.O.L.L.E systems, facilitating quick extraction in various tactical scenarios.

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.

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.

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.

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.

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.
