ExtremaRatio - Ferrum T knife - Black Warfare - 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.

ExtremaRatio - Ferrum Rescue multi tool - Black - knife
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.

ExtremaRatio - G.O.I. Caimano Nero N.A. Flipper - Knife
NON-automatic version of the Caimano Nero model
The Black Caiman is a tactical knife that Extrema Ratio, official supplier of Comsubin, has developed and delivered to the G.O.I. (Gruppo Operativo Incursori) of the Italian Navy. Its name recalls and pays homage to the heroic Caimani Neri del Piave, a department of Arditi of the Regia Marina and other components on a voluntary basis, which during the First World War crossed the Piave River by swimming to carry out raids in enemy territory.
Spear Point" 4 mm blade with asymmetrical rounding and partial sharpening of the counterbore to increase the penetration coefficient. The toothing on the blade allows you to cut cables and fabrics with high resistance preserving the sharpness.
It is a medium folder with a robust structure. The thick aluminum cheeks, thanks to the many processes of removal make the knife light and balanced. The end of the handle, which recalls the shape of the Helix/Timon group of the slow running torpedo (S.L.C.), serves to improve the grip for the rapid extraction of the knife from the pocket.
The DLC-coated titanium clip can be positioned at three different angles on either side to allow for maximum customization of the carry. Its shape is designed to minimize the bulk of the handle outside the pocket.
Among its endowments, besides the carbide glass breaker, there is also a safety, that when inserted, preserves from a dangerous accidental closing of the blade.

ExtremaRatio - BF2CD Knife Stone Washed - Classic Drop - knife
The BF2 is a "full size" lockable particularly suitable for professional use by military and police operators in the field. The handle is firm and comfortable; the clip, reversible and enveloping, becomes a useful and comfortable support for the thumb in "reverse grip". The grip is full with the characteristic lowered surfaces to engage the opening "pins" without protruding from the profile of the closed knife. The blade, available in a drop or a lot version, has a flat edge and, as in the BF1, a particularly thick and resistant tip. The blade locking mechanism is the tested LINER-LOCK, assisted by a safety mechanism to be operated manually protected by a casing.

Il BF2 è un chiudibile “full size” particolarmente indicato per l’impiego professionale da parte di operatori militari e di polizia sul campo. L’impugnatura è salda e confortevole; la clip, reversibile ed avvolgente, diventa un utile e comodo appoggio per il pollice in “reverse grip”. La guancetta è piena con i caratteristici piani ribassati per impegnare i “pin” d’apertura senza che sporgano dal profilo del coltello chiuso. La lama, disponibile in versione drop o tanto, ha l’arrotatura piatta e, come nel BF1, la punta particolarmente spessa e resistente. Il meccanismo di blocco della lama è il collaudato LINER-LOCK, coadiuvato da un meccanismo di sicura da azionare manualmente protetto da un carter.

ExtremaRatio - T911 Tuscania Rescue Tool - folding knife
On December 19, 1941, in Eluet El Asel, about 400 men from the 1st Royal Carabinieri Battalion Paratrooper faced the assault of 4 battalions of Indian troops of the British Army. Jumping from their trenches by launching improvised devices, the "Desert Lions", as Radio London called them, made the defensive line impenetrable by allowing thousands of Italian-German troops to withdraw safely. This was the first page in the long history of Italian paratroopers.
The Tuscania Paratrooper Regiment asked that the Extra Ratio T911 be specifically made as a commemorative knife for its 80th anniversary.
The T911 is a medium-sized folding light and designed for professional use by military operators. It is equipped with a modified spear point blade, flat edge, in Bohler N690 cobalt steel heat-treated to a hardness of 58 HRC, for the best compromise between strength, ease of regrinding and thread hold. The blade is 76 mm long, 4 mm thick, has a stone washed finish and rotates around an adjustable pin which allows to obtain the best fluidity in opening. A brace allows you to lock the pin in the best position.
The handle is in Anticorodal aluminum alloy with high strength black anodized finish and is milled to facilitate the transition from "reverse grip" handle to saber handle.
The blade is opened by means of a pin operated with the thumb. The knife uses a liner lock type blade lock and a safe ensures maximum hold even during heavy use. The safety lever is colored red for better visibility and engages in an advanced position for more instinctive use.
In the handle are integrated a seat belt cutter with easily available and replaceable cutter-type blade, a tungsten glass breaker, a stainless steel knot loosener and a screwdriver for adjusting the pointing optics, in AISI 420 steel. The clip , reversible and fixed at the end of the handle, allows a very deep port in the pocket, for less visibility.
The knife can be dismantled for cleaning and maintenance. With a total length of 194 mm and a weight of 145g, the T911 is easy to wear both in uniform and in civilian clothes.

ExtremaRatio - Resolza 10 - Black - pattada knife
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.

Until the early years of the '900 was commonly carry in your pocket a boxcutter by utility but, with a succession of cases of "misuse" of these objects, the law imposed the cutting or cutting-off of the tip of the blade to limit the harmfulness . Someone thought it well to take full advantage of the cutting edge of a blade typically already checked, taking as a pocket knife a straight razor, which became for a certain period of time a feared defensive tool.

ExtremaRatio - 185° RAO - 2018 Version - heavy folding knife
New version 2018 with improved grip: uses the same handle as the RAO II model
Folding knife made to specific requests of the Italian Army department 185 ° RAO (Regiment Acquisition Objectives) and currently supplied to the homonymous department. The supplied knife differs from the civil one only because of the total lack of writing or logos on the blade.
HISTORICAL SUMS ON THE DEPARTMENT:
The 185 ° RAO of the '' Folgore '' is a department with an ancient tradition, but very new. In fact, it was born on April 3, 2000 following the reconfiguration of the 185th terrestrial paratroop artillery regiment. Based in Livorno, it is an atypical department of the artillery weapon, currently inserted in the Special Forces basin.Entirely composed of voluntary personnel, the 185th RAO selects its components through the passing of a physical test and a qualification course on modules '' with increasing difficulty ''. The tasks entrusted to the RAO's men are many, but all very delicate: it is about gathering information on enemy objectives and 'passing them' to one's command. More generally, it can talk about '' recognition in sensitive areas ''. '' It is therefore evident - they stress to the Army - that the activity of the acquirer takes place mainly in hostile territory, in small self-sufficient nuclei that act in isolation ''.
RAO paratroopers are specialists in '' infiltration and exfiltration '' techniques and are able to move in the operating area '' for up to 8-10 days without external supplies ''. They know how to 'escape from capture, escape and escape from an' enemy controlled area '' and, above all, as '' identify, determine and evaluate objectives '' of strategic interest. Since 2002, the year of reconfiguration, the 185th Regiment detachments have operated in all the hottest operational theaters: from the Balkans to Afghanistan, to Iraq. Here they mainly carry out surveys for medium and long-range information purposes and for monitoring the area of responsibility of the Italian contingent.

ExtremaRatio - Ant Black Knife - N690 - Folding Knife
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 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 Black version utilizes Böhler N690, hardened to 58 HRC for the best balance between edge retention and toughness, a type of steel used by Extrema Ratio for most of its knives.
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.

ExtremaRatio - Ant Rescue Red Stone Washed Knife - M390 - Folding Knife
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.

ExtremaRatio - RAO C - N690Co & Aluminum Black - folding knife
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.

ExtremaRatio - MF1 Rough Black Knife - folding knife. The MF stands for Medium Folder
This line of knives fits between the Basic Folders series and the Heavy Folders series. The typical mechanism of the series is the LINER-LOCK. The overall structure is robust. All knives in the MF series have a rear glass breaker. They also feature the innovation of the adjusting locknut on the blade fixing pivot.
By removing the locknut it is possible to tighten or loosen the central pivot as desired, to achieve the desired opening fluidity. It will be enough to lock the pivot screw with the locknut to fix the adjustment. The hemispherical milling on the handles facilitate the change of grip from "saber grip" to "reverse grip". The clip is reversible.
The BC (Belt Cutter) version features a rear seatbelt cutter with an easily obtainable and replaceable industrial cutter blade. In addition, a slotted screwdriver is inserted inside the handle that allows for the adjustment and calibration of firearm optics. This version is produced with a rough grip to offer a better grip.

More than just a damask, Coreless steel made by Japanese Takefu Steel comes with over 70 layers of VG10 and VG2 stainless steel welded, forged and coated between them so that you can form a lightweight, slim and durable blade with a spectacular damask outer pattern.
The peculiarity of Coreless steel, unlike conventional rolled steel or Japanese San-Mai, is that it does not have a hard core steel that is used for the cutting edge but has both the VG10 and VG2 steels arranged to form the cutting edge so alternating and sequential to each other.
This particular construction gives the blade - compared to the two steels that make it, individually taken - greater resistance to oxidation, higher surface hardness (up to 61.5HRC), 25% more than cutting capacity, 25% more than the wire hold capacity and 25% more resilience making the blade more robust and less subject to breakage.
Thanks to this latest steel, Takefu Steel has been rewarded on Japanese territory for research and development and innovation in the cutting-edge landscape. Coreless steel has already been chosen by major brands such as Kai and Mcusta Zanmai who since 2017 proposed it on their top productions of professional kitchen knives.
