The blade of the DOBERMANN IV S600, made from Böhler S600 steel, offers excellent hardness, wear resistance, and toughness, thanks to the high content of molybdenum, tungsten, and vanadium. The addition of cobalt promotes the formation of small carbides, further improving wear resistance. With a hardness of 64 HRC, it ensures long-lasting edge retention. The “EXP DARK” teflon coating protects the steel from oxidation.

DOBERMANN IV S600 features a green forprene handle with a glass-breaking tang. It comes with a green cordura thigh sheath, adaptable for both left and right-handed users and compatible with the M.O.L.L.E system.

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. This mechanism allows the user to open the blade quickly and easily, even with just one hand. The locking system adopted is the well-tested liner lock. The reversible clip is positioned on the back.

Ferrum T is available in 2 versions: the first, FERRUM T Black Warfare, equipped with a black handle and Geotech Camo blade, the innovative and original Extrema Ratio camouflage pattern, created by laser engraving.

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.

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.

Packaging: cardboard box with Extrema Ratio logos
Notes: Rear Skull Crasher - Derived from the Black model, adopted by the 4th Alpine Parachute Regiment.

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. The double retention system integral with the sheath is made up of four pressure elements that work only two at a time, depending on right/left use, while in the nylon textile part there is a button that allows you to secure the knife to the sheath . The end of the sheath has a hole that allows you to expel liquids or residues inside. The possibility of applying belt clips, ulticlips, malice clips makes it extremely versatile. It is also possible to hook the sheath to the M.O.L.L.E. system. weaving the paracord lanyard.

The S-thil Black Warfare is supplied in an IP67 certified watertight Polypropylene technical case, with pressurization valve, resistant to atmospheric agents, dust and shocks. Inside there are also the Nylon sheath, the double ULTICLIP and the double grain sharpening plate (ceramic abrasive and synthetic diamond).

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.

Selvans Expeditions, as well as the Selvans model from which it derives, was born from the collaboration between Extrema Ratio and the Master instructor F.I.S.S. (Federazione Italiana Survival Sportivo e Sperimentale) Daniele Dal Canto. This tool is the result of the modification of the ONTOS, military survival knife, realized in order to accentuate and maximize the performance of the knife.

Selvans Expeditions uses Böhler N690 steel heat treated to 58 HRC with MIL-C-13924 burnishing and stone washed surface treatment (Dark Stone finish). 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.

The survival kit (not included and purchasable separately) has been optimized and includes whistle, chainsaw, drinking pads, compass, brass wire, flintlock, flashlight, paracord 2,5 mt. and sharpener.

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.

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.

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.

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 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.

Stone Washed version that uses Böhler N690 heat treated at 58 HRC, chosen for the reliability it has shown over the last 20 years due to its resistance to oxidation and durability of the wire.

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.

On December 19, 1941, in Eluet El Asel, about 400 men from the 1st Royal Carabinieri Battalion Paratrooper faced the assault of 4 battalions of Indian troops of the British Army. Jumping from their trenches by launching improvised devices, the "Desert Lions", as Radio London called them, made the defensive line impenetrable by allowing thousands of Italian-German troops to withdraw safely. This was the first page in the long history of Italian paratroopers.

The Tuscania Paratrooper Regiment asked that the Extra Ratio T911 be specifically made as a commemorative knife for its 80th anniversary.

The T911 is a medium-sized folding light and designed for professional use by military operators. It is equipped with a modified spear point blade, flat edge, in Bohler N690 cobalt steel heat-treated to a hardness of 58 HRC, for the best compromise between strength, ease of regrinding and thread hold. The blade is 76 mm long, 4 mm thick, has a stone washed finish and rotates around an adjustable pin which allows to obtain the best fluidity in opening. A brace allows you to lock the pin in the best position.

The handle is in Anticorodal aluminum alloy with high strength black anodized finish and is milled to facilitate the transition from "reverse grip" handle to saber handle.

The blade is opened by means of a pin operated with the thumb. The knife uses a liner lock type blade lock and a safe ensures maximum hold even during heavy use. The safety lever is colored red for better visibility and engages in an advanced position for more instinctive use.

In the handle are integrated a seat belt cutter with easily available and replaceable cutter-type blade, a tungsten glass breaker, a stainless steel knot loosener and a screwdriver for adjusting the pointing optics, in AISI 420 steel. The clip , reversible and fixed at the end of the handle, allows a very deep port in the pocket, for less visibility.

The knife can be dismantled for cleaning and maintenance. With a total length of 194 mm and a weight of 145g, the T911 is easy to wear both in uniform and in civilian clothes.

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.

Extrema Ratio developed the first knife of a new production line, called CONTACT.

It has a blade with a lance-shaped profile, a flat grinding and a diamond-shaped geometry. It has got a lower guard branch to protect itself from incidental cuts, upper jumping to improve grip, concave fuller along the length of the blade and a generous thickness blade (6.30mm) the now famous Requiem, revisited in proportions and in some technical features. The first of a new line of multipurpose knives.

The blade is made in Böhler N690 steel with a hardness of 58 HRC and a chemical burnishing coating for the Black version. All other colors in production have got a blade with Stone Washed finishing. The handle is still in forprene. It is more assembled by the side screws but thanks to the shank in truncated cone-shaped stainless steel that is screwed to the bottom and goes to fit inside a special seat, which makes it solid. In this way the knife is well balanced. The sheath is minimalist; most of the fabric has been cut off; it has got a 2nd level retention system, remembering the style of the model it was inspired by.

The main shell is injection-molded in shockproof nylon. The secondary retention system is reversible for ambidextrous users. The blade is guided through the conception of the blade. To extract the blade, to pressure the trigger will be sufficient, thus releasing the safety that holds securely in the sheath. In the horizontal slits of the sheath of a system, which fixes the blade to avoid shaking noises when it is stored inside. The back side of the nylon sheath is M.O.L.L.E. compatible.

The textile part is reduced to its minimum and has got the classic two-button safety strap with a belt loop Extrema Ratio aims to reduce the size of the knife, but not saving on the structural strength and safety accessories.

SILENTE is the name of the knife taken from the motto "SICUT NOX SILENTES" by N.O.C.S. Central Security Operations Unit, special anti-terrorist unit of the State Police.

SILENTE was presented to the Department, the Authorities, the Minister of the Interior and the Chief of Police on the occasion of the forty-year ceremony of the foundation of the NOCS.

SILENTE is a unique model of its kind that fulfills equally unique needs: the handle is divided into two parts and creates the handle of a clamp placed in the end of the handle. With it, in addition to taking on everything that has the appropriate dimensions, it is possible to cut wire, wire, steel cables, etc. and last but not least, it can be used as a window breaker, given the tungsten carbide insert at the end.

The sheath protects the cutting edge during all these uses, allowing it to be used safely, but it can also release the blade with a fast and silent retention system. Adaptable to thigh use and applicable to the M.O.L.L.E system, it is integrated into the operator's equipment using the least possible space.
