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.

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

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 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.

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.

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.

Born from the revisitation of the 39-09 model, the Nimbus was developed and chosen by the 183rd "Nembo" Paratrooper Regiment as a commemorative knife of the events of Case Grizzano which on 19 April 1945 saw the Nembo paratroopers engaged against the paratroopers of a German division . The clashes raged for 12 hours and were often resolved by hand-to-hand combat with the white weapon. A few days after the end of the Second World War one third of the battalion's men remained on the field, but their sacrifice led to the conquest of the battle. The knife in addition to wanting to commemorate an important event of our Armed Forces is the result of a development that has been carefully studied also in the technical aspects, so as to make it suitable for a concrete operational use.

Particular attention has been paid to taking care of the dimensions, the shape and the search for solutions such as the kydex sheath, which is designed to make the knife an instrument capable of adapting to the most complex requirements of the port.

The light and compact blade meets the demands of a modern tactical knife today.

Born from the revisitation of the 39-09 model, the Nimbus was developed and chosen by the 183rd "Nembo" Paratrooper Regiment as a commemorative knife of the events of Case Grizzano which on 19 April 1945 saw the Nembo paratroopers engaged against the paratroopers of a German division . The clashes raged for 12 hours and were often resolved by hand-to-hand combat with the white weapon. A few days after the end of the Second World War one third of the battalion's men remained on the field, but their sacrifice led to the conquest of the battle. The knife in addition to wanting to commemorate an important event of our Armed Forces is the result of a development that has been carefully studied also in the technical aspects, so as to make it suitable for a concrete operational use.

Particular attention has been paid to taking care of the dimensions, the shape and the search for solutions such as the kydex sheath, which is designed to make the knife an instrument capable of adapting to the most complex requirements of the port.

The light and compact blade meets the demands of a modern tactical knife today.

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.

This knife was designed and perfected in every detail for its primary use in the marine environment. The blade has a flat rounding that allows symmetrical cutting work with wider support. The tip, on the other hand, which is thick and durable thanks to the tanto version, allows greater penetration and a sharper, more precise cut. The stone washed finish process facilitates locating in the marine environment.

The structure of the handle, made of anodized anticorodal aluminum, features a design with milling in concentric circles and lightening and anti-slip perforations so as to facilitate rinsing from saltiness. A small slot is cut into the middle of the cheek piece to allow for tightening or releasing smaller shackles. BF2 V is equipped with reversible clip; adjusting screw retainer for closing and opening the blade; 70-mm. knot shock ankle with fastening mechanism; and correctable. The presentation of the BF2 V took place on the Amerigo Vespucci School Ship.

The knife, although borrowing the line, the structure and the proportions of the original, has been strengthened, enriched with functional modifications and made with materials with modern military specifications.

Unexpectedly, the result of these few modifications is an extremely functional and effective dagger, absolutely competitive with the best contemporary military knives.

The sheath is rigid from the ankle, in the typical manner in which the bayonet is carried by Italian paratroopers.

.

The particular situation created in the early years of the 1914/18 war, now mired in increasingly complex and protected trenches and fortifications, favored the formation of men who, little by little, specialized in the coup.

Our assault units, the Arditi, had their dagger. It was obtained from the pieces cut away by the long blades of the Vetterli 1870 bayonets, which in the narrow trenches, in the corridors, between the reticulars were only an obstacle. It was certainly a rustic weapon, of recovery, not too beautiful but certainly inexpensive, light, not cumbersome and in expert hands also effective.

Today, on the occasion of the centenary, we remember this important page of Italian military history with a limited series of celebrations of 1918 copies. This version has a burnished blade, a polymer handle and a black cordura sheath.
