Passion for knives

TACTICAL CUTLERY ENTERS THE KITCHEN!
Silver Talon is the knife designed by Extrema Ratio to celebrate the famous "Fiorentina" steak. This knife made of machined steel from solid, thanks to its integral structure, does not allow deposits of organic material.

The special claw shape of the blade allows it to cut dishes without the blade ever touching the plate with the edge but rather with the tip. Silver Talon, when used correctly, will retain its original sharpness for a very long time. For those who love precision tools even on the table.

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.

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.

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.

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.

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.

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.

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.

Extrema Ratio S-THIL Black Warfare, a special version of the S-THIL model, is a backup knife with a monolithic structure machined from a single piece of 5 mm thick BOHLER N690 steel, developed in collaboration with the designer Thilo Arnd Schiller. The spear point type blade is hardened to 58 HRC in order to obtain the best balance between edge retention and strength, has a false edge in the upper part which enhances the characteristics of penetration and tip work, and is equipped with a Full length furrow flowing elegantly from blade to grip.

The blade is milled integrally with the knife to enhance its compactness and lightness, maintaining a minimum thickness even with a profile that recalls the classic Extrema Ratio handle. This profile forms two small guards and a comfortable thumb rest in order to prevent the hand from slipping towards the blade. On the end there is a skull crusher with a diamond-shaped tip and a slot that allows you to attach a wrist strap to the knife or to equip the handle with paracord winding.

The special Black Warfare version uses the innovative and original Geotech Camo pattern, created by laser engraving. The molded nylon sheath has been designed to be extremely flat and with very small lateral dimensions, in order 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 cutting edge of the blade to the right or left.

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.

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.

The BF2 is a "full size" lockable particularly suitable for professional use by military and police operators in the field. The handle is firm and comfortable; the clip, reversible and enveloping, becomes a useful and comfortable support for the thumb in "reverse grip". The grip is full with the characteristic lowered surfaces to engage the opening "pins" without protruding from the profile of the closed knife. The blade, available in a drop or a lot version, has a flat edge and, as in the BF1, a particularly thick and resistant tip. The blade locking mechanism is the tested LINER-LOCK, assisted by a safety mechanism to be operated manually protected by a casing.

Il BF2 è un chiudibile “full size” particolarmente indicato per l’impiego professionale da parte di operatori militari e di polizia sul campo. L’impugnatura è salda e confortevole; la clip, reversibile ed avvolgente, diventa un utile e comodo appoggio per il pollice in “reverse grip”. La guancetta è piena con i caratteristici piani ribassati per impegnare i “pin” d’apertura senza che sporgano dal profilo del coltello chiuso. La lama, disponibile in versione drop o tanto, ha l’arrotatura piatta e, come nel BF1, la punta particolarmente spessa e resistente. Il meccanismo di blocco della lama è il collaudato LINER-LOCK, coadiuvato da un meccanismo di sicura da azionare manualmente protetto da un carter.

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.

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.

RESOLZA, a term of ancient origin, is today one of the most famous traditional knives of our country. The name suggests the razor by chance.

It was born in Sardinia centuries ago and has accompanied its inhabitants until today in the daily work of a peasant and pastoral life, following them even when its men were called to war. The chronicles of the Sassari Brigade during the First World War cite this knife among its soldiers' equipment.

We wanted to make a tribute by revisiting it according to our canons, without wanting to hurt any of the prestigious Sardinian artisans who still today pass on the tradition and wisdom of their ancestors. The dimensions and proportions are the original ones of a 10 cm blade, but the materials and technologies are those of our production. The handle revised in our style, the blade most faithful to tradition. In addition to the original, it has the blade lock open.
