The VULPIS series was born out of the need to create a compact, versatile, multi-purpose knife with a modern design that perfectly matches historical products. The inspiration for the creation of this line starts from the DUCA, the name of the typical multi-purpose knife of the people of Maniago, a knife that originated in the second half of the 1800s in Maniago, when hunting knife sharpeners with different sized blades, ivory toothpicks and tweezers for removing thorns were made.

These knives were presented at the 1888 National Exposition in Turin by the Bet Giovanni company, which won a gold medal for the quality of its products. So it was that, most likely, Luigi Amedeo di Savoia, Duke of the Abruzzi, decided to visit one of the company's two stores in Turin, where he saw and ordered the four-bladed multi-purpose knife, which he chose as part of the equipment for the North Pole expedition he commanded in 1899.

T4000S is a reworking of the Japanese Wakizashi short sword that the Samurai carried at all times in contact with the body. It is a timeless tactical tool that does not follow any fashion but faithfully respects the Extrema Ratio philosophy aimed at fulfilling all functional requirements.

This model continues Extrema Ratio's purest Tanto series designed especially for lovers of the Japanese blade profile, who do not want to give up typical tactical accessories such as textile sheath and special polymer handle. The blade is made of Bohler N690 steel, heat-treated to a hardness of 58 HRC.

The handle, in black coloring, is made of Forprene, an elastomer whose exceptional resistance to extreme conditions makes it part of the "NATO standard." The black-colored Cordura scabbard is and equipped with a MOLLE system that allows it to be carried on tactical vests and general belts and ensures that the razor-sharp blade can be carried in total safety by protecting it from shocks that could reduce its efficiency.

The Black Caiman is a tactical knife that Extrema Ratio, the official supplier of the Comsubin, developed and delivered to the G.O.I. (Gruppo Operativo Incursori) of the Italian Navy. Its name evokes and pays homage to the heroic Black Caimans of the Piave, a department of Royal Navy Arditi and other components on a volunteer basis, who during World War I swam across the Piave River to carry out raids into enemy territory.

The titanium clip can be positioned at three different angles on either side to allow for maximum customization of the port. Its shape is designed to minimize the bulk of the grip outside the pocket.

Among its features, in addition to the carbide glass breaker, is a safety, which when engaged, preserves against a dangerous accidental closing of the blade.

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 Ant Rescue, unlike other versions, has a cheek piece in red coloration that allows the operator to more easily locate the knife in case of a fall. This version is equipped with a specific serration that allows cutting ropes and even high-tensile aramid materials. Moreover, this model has a tapered tang that serves as an emergency screwdriver. The Ant Rescue has been developed according to the needs expressed by the "Italian Army Alpine Troops School".

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 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.

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 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. The second, FERRUM T TACTICAL MUD, with anodized handle in the new gray-green color and blade with MIL-C-13924 bluing.

The reversible clip is positioned on the back.

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.

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. On the back there is also a hard metal glass breaker.
