Knife - Essential Tool for Camping, Outdoor Adventure and collection

The lines are stripped down to the essentials; the profile is clean and continuous. This isn’t an aesthetic choice, but the result of a function-oriented design. Every element exists for a specific reason; everything else has been eliminated.

The skeletonized full-tang construction and 4.8 mm blade thickness reflect a different approach: lightness where needed, strength where it counts. The 80 mm blade and 191 mm overall length define a compact yet uncompromising tool.

The AERO FX is built around materials selected to ensure durability, reliability, and minimal maintenance: an Anticorodal aluminum handle and a Nitrogen steel blade with a MIL-C-13924 burnished finish, designed to offer corrosion resistance, good edge retention, and ease of resharpening.

The carrying system consists of a dual-configuration Kydex sheath: an ultra-flat, slim solution for discreet carry and an additional interface to expand attachment options. The configuration can be adapted using the Malice clip or paracord, both of which are included.

Following the success of the FULCRUM multi-purpose knife, the bayonet version was developed, designed for even more specific and demanding applications. Like the FULCRUM, the bayonet is an extremely robust and versatile knife: the blade withstands breaking loads exceeding 150 kg, the tip is extremely durable, and the profile allows for extended use without compromising the sharpness of the cutting edge. The forward-shifted center of gravity, combined with the blade’s weight, ensures excellent performance in the most demanding fieldwork, offering power and control even under the toughest conditions.

The 2026 EVO model introduces a major design update: the knife’s tang now features a completely redesigned structure, engineered to improve structural rigidity and optimize stress management during the most intense use, while also offering a more precise and secure feel during technical tasks.

The FULCRUM is a milestone among multi-role knives.

Deployed on a large scale in Afghanistan as standard equipment by components of the Italian "Nibbio" mission, it is part of an experimental individual equipment renewal project undertaken by the Alpine Troops Command. During the preparation for this important mission, Alpine Troops Command coordinated a team of companies in the production of a complete and renewed experimental individual equipment.

The FULCRUM is an extremely robust and versatile knife.
The blade can withstand breaking loads in excess of 150 kilograms, the tip is extremely strong and the tanto profile allows the knife to be worked on for a long time without affecting the sharpness of the last section.
The advanced center of gravity and weight of the blade make it suitable for heavy field work.

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.

The Herring dagger is one of the most loved military knives by enthusiasts.

Its original name is Fairbairn Sykes or Commando Dagger and it was present in the endowment of the British Commandos.

A dagger that entered Italian history in World War II, thanks to the exploits of young soldiers of the 1st "Folgore" Reconnaissance Squadron, who were equipped with this weapon during Operation Herring. He has behind him a heroic piece of history that is rarely talked about, despite the fact that these young boys, thanks to their devotion to the cause and their courage, have written an important page in Italian history.

Extrema Ratio wanted to pay homage to this dagger trying to remain faithful to the original forms, while using the most modern production techniques.

The very special hand-made finish of the handle simulates the aging of brass and gives the dagger a dated look, similar to the original.

The dagger was developed in collaboration with the 185th RAO and adopted as a ceremonial commemorative dagger for the 20th anniversary of the regiment's establishment and the 75th anniversary of the Herring mission.

The knife is equipped with a polymer case with historical frieze of the F Squadron, leather / kydex sheath with brass tip and two commemorative scrolls.

PLEASE NOTE:
NE version, simulacrum replica with rounded tip and blunt blade, to allow free sale and possession according to the current regulations in force on the Italian territory.

We warn that any subsequent modifications and sharpening made to the blade modify the status of simulacrum of the Herring NE. In this case it will be subject to the regulations in force in the respective countries. Furthermore, these changes will void the Extrema Ratio warranty.

S.E.R.E. 2, adopted by the Operational Group of Italian Navy Incursors, is the development of the S.E.R.E. 1, created by a study group composed of Special Forces operators, martial artists and experts in survival techniques. This variant 2 has been revised according to the needs expressed by the Department.

The acronym S.E.R.E. refers to the four principles "Survival, Evasion, Resistance and Escape" which make up the training program provided to military personnel at high risk of capture.

The S.E.R.E. 2 is suitable for both tip and cut use. The unique grip, unlike the classic blades of this type, is fixed between the index and the middle, thus forming a single axis from the tip of the blade to the user's wrist, allowing its use also in reverse grip. The handle has the same ergonomics as the butt of a firearm; this grip allows an instinctive and immediate use, being able to easily integrate the training in the training activity.

The geometry of the tip ensures maximum penetration, at the same time its axial profile with a triangular base protects its resistance. The design of the blade has on one side a partially serrated profile to favor the cutting of cordages, and on the other hand a classic cut or straps that, unlike the previous model, has re-sharpening and interchangeable blades.

The central loop, which has the dual function of lightening and turn-crickets, recalls the maritime origins of its creators. The peculiarity of the knife is that it has been specifically designed to be used even without the handle; the two holes in the part dedicated to the handle facilitate assembly.

The kydex sheath has a basic retention that can be used alone for operators who need extremely fast knife use, and a removable locking lock if necessary. The knife is supplied with double safety for ambidextrous mounting. An insert with a flat-blade screwdriver is available as an accessory. Comes with belt clip for belt fastening and paracord for fixing on the M.O.L.L.E. system.

"Using the gun, knife or other weapon for us is the same thing: it's just the extension of the hand." Quote from a commander of the ward.

The Fulcrum C Black is the compact version of the famous Fulcrum knife, designed by Extrema Ratio to offer maximum reliability in a smaller, easily transportable format. Designed for tactical and emergency use, this fixed-blade knife stands out for its strength, ergonomics and versatility.

The blade measures 110 mm and features a tanto profile, with flat sharpening and 40 mm partial teeth, ideal for effectively cutting tough materials such as ropes and fabrics. Made of Böhler N690 steel hardened to 58 HRC, it is protected by a black burnished MIL-C-13924 finish, which provides corrosion resistance and reduces glare.

The handle is made of Forprene, a material resistant to weathering, impact and mechanical stress, offering a secure grip even in extreme conditions. The ergonomic and compact handle makes the Fulcrum C particularly suitable for use in confined spaces or as a backup tool.

The knife features a rigid ABS sheath, which can be mounted vertically, horizontally, or at a 45-degree angle, offering great flexibility in carrying and quick draw.
