Ant is the most compact of the Extrema Ratio folding knives. Despite its small size, this model has an extremely robust, resistant and reliable structure. The handle is made up of two different elements: the grip made of anodized anticorodal aluminum and the tempered steel frame which also performs the function of locking the blade (Frame Lock System). This mechanism requires that part of the frame is folded inwards, firmly fixing the blade in the open position, increasing the operator's safety when using the knife. On the tang there is a slot for inserting a lanyard, on the right side of the handle there is a steel clip that allows concealed carry in the pocket. Ant is available in 4 versions with two different types of steel both supplied by Böhler, an Austrian company with which Extrema Ratio has been collaborating for more than 20 years using its proven materials for the production of its blades. The Ant Black and Ant Black Stone Washed versions use Böhler N690, hardened to 58 HRC for the best balance between edge retention and strength, a type of steel used by Extrema Ratio for the majority of its knives. For the Rescue Red Stone Washed and Black Stone Washed versions M390 Extrema Ratio uses Böhler M390 steel heat treated to 61 HRC which, thanks to a powder metallurgical production process, guarantees cutting effectiveness, resistance to wear and tear over time. 'oxidation. The blade is sheep foot shaped and has a small slot on the top to facilitate opening. Its particular structure, thanks to the straight edge, allows the user to comfortably rest his fingers on the back of the knife and use it with ease. Ant Rescue, unlike the other 3 versions, has a red grip that allows the operator to find the knife more easily in the event of a fall. This version is equipped with specific teeth that allows it to cut rope and even high tenacity aramid materials. This model is also equipped with a tapered shank which acts as an emergency screwdriver. Ant Rescue, thanks to its particularities, was chosen as an equipment by the "Alpine Troop School of the Italian Army". Extrema Ratio Ant is available in the following versions: -Ant Black (grip in black color and burnished blade in Böhler N690 steel) -Ant Black Stone Washed (grip in black color and stone washed blade in Böhler N690 steel) -Ant Black Stone Washed M390 (grip in black color and stone washed blade in Böhler M390) -Ant Rescue Red Stone Washed steel(red grip and stone washed blade in Böhler M390 steel).

RESOLZA is an ancient name, reminiscent of the italian word for razor. The centuries old Sardinian "resolza" is one of the best-know traditional knives in our country - to this day it's been the constant companion to island farmers and shepherds in their everyday work. It followed them even when they were called to war: chronicles of the Sassari Brigade during World War I mention the knife as part of the troopers' equipment. Our attempt to revisit this traditional design according to our own standards is meant as a tribute, not to disregard Sardinian craftsmen still practicing the old ways of knife-making and keeping ancestral traditions alive.

This series of extremely compact folding knives is the result of interaction between Extrema Ratio and the military and police with whom we collaborate. The intention was to create a folding knife for everyday use, simple, essential and functional. The basic folding knife: the BF1 (Basic Folder n°1). There are two blade patterns: Tanto and Drop. All the blades are burnished through zirconium carbonitruration, the handles are burnished through anodization. The blades have flat grindings and the points are especially thick and resistant (a characteristic peculiar to this series). The "Classic" handle is full with the characteristic lowered flat zone to enable the use of the opening "pin" without emerging from the profile of the closed knife. The clip is another innovation, it is reversible, positioned on the back of the blade and hugging the tang of the knife so that when the knife is inserted in a pocket the tang does not stick out and only the clip is visible. The blocking mechanism is the approved "liner lock" Captions The clip allows it to be carried discreetly. The point is extremely robust. Desert Warfare finish is special order; additional 4-8 weeks lead time. Free shipping.

Up to the early 1900s, people commonly carried pocket utility knives. However, due to rampant “misuse”, laws were passed to the effect that all such knives were to be clipped at the blade-tip in order to diminish their dangerousness as weapons. Some people then figured they’d get the greatest effectiveness out of the sharp edge of a traditionally flat-point blade shape, and took to carrying straight razors. Thus, the straight-razor was for a time regarded as a fearsome weapon of self-defense. Such a “misuse” of the common straight-razor inspired our T-RAZOR design. Free shipping.

BF2 CD M390 TACTICAL GREY is a “full size” EDC knife ideal for professional use by military and police operators in the field. Thanks to its practicality, this versatile every day carry is also perfect for many everyday situations.

The blade, characterized by a flat grind and a particularly thick and resistant drop tip, is coated with a DLC (Diamond-Like Carbon) surface treatment based on Carbon which makes it hyper resistant to abrasion and chemical aggression.
The steel used is Böhler M390 heat treated at 61 HRC which, thanks to a powder metallurgical production process, guarantees cutting efficiency, wear resistance and oxidation over time.
The blade locking mechanism is the proven LINER-LOCK, assisted by a manually operated safety mechanism protected by a casing.

Ferrum Rescue is a tool designed for rescue missions, developed in collaboration with Andrea Micheli, military and law enforcement expert, journalist and shooting instructor. It has an extremely compact grip and three blades carrying out the following functions: The first and main blade is 3 millimetres thick. It is designed for a much heavy use and to prevent the edges of the other two blades from wearing prematurely. Its serration allows it to cut bigger ropes or textiles, whereas the plain edge acts as a proper knife. The second blade is a scalpel, which can be used to make extremely clear cuts and perform emergency actions. The third and the smallest, located on the back of the main blade, is a lanyard cutter that can also be employed to cut aramid paracords. The combination of the main blade and the scalpel allows the user to operate an emergency cut to free the injured from their clothes. Both lanyard cutter and scalpel can be replaced. Ferrum Rescue has a thin and compact shape, its anodized anticorodal aluminum handle scales making its grip light, slim as well as resistant. It can be placed in a pocket, in small flashlight holsters or in a single M.O.L.L.E. system webbing. It is also equipped with a hard-metal glass breaker on the bottom part. It comes with a flipper assisted opening. The blade rotates on ball bearings resulting in a fluid and firm movement. This mechanism allows the user an easy and rapid opening of the blade, even with just one hand. The locking mechanism is the time-tested liner lock. The reversible clip is located on the back. Ferrum Rescue is available in two versions, Red and Black; the first has a clear rescue connotation as it helps the user find the knife in the event of a fall.
