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 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.

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.

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.

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.

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.

The Extrema Ratio Misericordia was adopted by the 4th Alpine Paratroopers Regiment which helped develop and test the product. It is a tactical fixed blade knife, extremely light and compact, it can be used both as a main knife or as a backup blade.

The blade is made of Böhler N690 steel, heat-treated to a hardness of 58 HRc, it is 118 mm long, 4mm thick and has a flat edge.

The profile is of the spear point type, with a full length fuller which makes the blade even lighter and with a false counter-thread at ¾ length. The blade is available with the classic Extrema Ratio MIL-C-13924 black finish.

The handle in fiberglass-reinforced nylon (FRN) features the classic Extrema Ratio recesses that make the grip safer and is fixed to the tang by means of a through screw.

On the rear end the handle flows connecting with a large ring, which allows the use of martial arts techniques and ensures a very solid grip to the hand, equipped with a "skull crusher" appendix in hard metal.

The overall weight of the knife is just 87g. Being a knife designed for professional use, much attention has been paid to ease of port, accessibility and extraction in case of need. The knife is secured to the sheath by a quick-release safety catch that can be easily reversed for use by left-handers.

The sheath is made of highly resistant Nylon, it is very versatile and two adjustable loops allow it to be fixed inside the loops of M.O.L.L.E.

The sheath is equipped with a conical invitation to facilitate the re-insertion of the knife while a simple pressure on the trigger safety allows it to be extracted quickly and instinctively.

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.
