FAT BOY is the strongest fixed blade knife Extrema Ratio has ever produced. It is the first knife made of N690Co steel (58HRC) with a thickness of 8.6 mm. The total weight of this model is 1 kg.

The blade, characterized by a completely flat edge, has a special tip structure that not only combines the ability to penetrate with the possibility of using it as a wedge, but also protects the main cutting edge. Thanks to its shape and width, it can also dig small holes in the ground in emergency situations.

The thick spine, flat at the end, gives the tool greater mass and a striking surface that is useful for driving stakes and hammers.

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.

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.

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

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 operator 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.

Extrema Ratio Misericordia Desert, which preserves intact all the features of the famous Misericordia model adopted by the 4th Alpine Parachute Regiment, derives from the commemorative dagger made on the occasion of the 140th anniversary of the 4th Alpine Regiment and the 70th since the founding of the Alpine Paratroopers.

It is a tactical-type fixed-blade knife designed for those instances when the knife must be extremely light and compact. The new desert coloring also makes this model available in a shade in line with the most common needs of modern operational departments.

The blade is milled from Böhler N690 steel, hardened to 58 HRC for the best balance of edge retention and strength, is 118 mm long, 4mm thick, and has a flat edge. The weight of the knife is just 87g. The profile is a spear point type, with a full-length shank that makes it even lighter and with a ¾-length false counterblade. The finish is a stone washed type.

The knife's polymer handle features classic Extrema Ratio shells that make for a more secure grip and is attached to the tang by a through-screw. On the rear end the handle flows connecting with a wide ring equipped with a "skull crusher" appendage: a ring that allows the use of martial arts techniques and ensures the hand a very solid grip. In this version the handle is in Desert coloring.

Since this is a knife designed for professional use, much attention has been paid to ease of carrying, accessibility and extraction in case of need. The knife is secured to the sheath by a quick-release safety that can be easily reversed for left-handed use. The sheath is also in Desert coloring, made of high-strength Nylon, very versatile and equipped with 2 adjustable loops that allow it to be attached to M.O.L.L.E systems, facilitating quick extraction in various tactical scenarios.

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.

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 sheath is minimalist, stripped of most of the fabric adopting a retention system of 2nd level, going to recall the style of the model to which it is inspired. The main shell is made by injection in shockproof nylon. The secondary retention system is reversible for the ambidextrous portability of the knife.

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.

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.

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.
