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.

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 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

Notes: -

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.

Satre Expeditions, as well as the Satre model from which it derives, 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 or as part 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 skeletonized structure, allows you to customize the knife using Paracord as a coating for the handle.

Satre Expeditions uses Böhler N690 steel heat treated to 58 HRC with MIL-C-13924 burnishing and stone washed surface treatment (Dark Stone finish). It comes with a desert-colored pre-formed kydex sheath on which you can attach the Firesteel for lighting fires (provided inside the box).

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.

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.

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

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.

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 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.

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.
