  2. 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.

  10. ExtremaRatio - Frame Rock Titan Knife - Blue Satin - PRIVATE COLLECTION - folding knife

    Knife withdrawn from a private collection - In like new condition - Never regrind - Checked and certified by our in-house Coltelleria Collini laboratory.

    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 a titanium handle that offers great resistance while being very light. The integrity of the frame-lock system is guaranteed against wear by an easily replaceable hardened steel insert.

    Unlike its drop-point predecessor, the Rock frame has a 75mm long, 6.0mm thick spearpoint blade fitted with a fuller for further lightening. The blade is made of Bohler N690 steel, heat treated to a hardness of 58 HRC. The same is available with a black finish with DLC treatment or satin.

    To make opening even more fluid and without uncertainty, the blade rotates on ball bearings. This mechanism allows the user to adjust the force necessary to obtain the release of 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 and solid handle and the well-proportioned blade allow this knife to tackle heavy tasks. The Frame Rock weighs less than 200g, making it somewhat light for such a sturdy knife. Comes inside an ABS box.

    Intended use: collection / CQD

    Type of production: industrial,
    Blade: N690Co stainless steel
    Blade treatment: Satin finish
    Country of production: Italy

  11. ExtremaRatio - Satre - S600 Black EXP Dark - Neck Knife

    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 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.

     

    Intended Use: Neck Knife / Hiking / Utility

    Production type: industrial
    Country of production: Italy
    Blade: Carbon steel Bohler S600 64HRC
    Blade treatment: Black EXP DARK
    Handle:in carbon steel Bohler S600 64HRC

  12. ExtremaRatio - Col Moschin Satin knife in San Mai V-TOKU2 - Limited Edition - knife

    Japanese steel blends with Italian excellence

    For this 2020 collaboration, exclusive of Collini Cutlery, we have decided to propose a series of best sellers produced by Extrema Ratio. Knives made with the famous San Mai steel produced by the Japanese Takefu Steel. Specifically, we used V-Toku2 carbonaceous at 62 / 63HRC for the central plate and SUS410 stainless steel for the two external plates, in order to guarantee a very high cutting capacity, penetration and sealing of the wire together with an ease of re-sharpening. and maintenance but at the same time the blade has a remarkable resistance to corrosion and an important increase in resilience given by the type of external steel and by the laminated structure.

    Col Moschin model: for this First Production Run a run of 11 pieces was produced, numbered from 1 to 11.

    Special purpose cutting knife, specially developed for the 9th Col Moschin Parachute Assault Regiment, elite unit of the Folgore brigade.

    Use: tactical, sports, hiking, collection

    Blade: integral, in laminated Japanese steel (San Mai) with V-Toku2 (carbonaceous) cutting edge at 62 / 63HRC and external SUS410 (stainless steel) scales
    Handle: forprene
    Blade length: 160mm.
    Blade thickness: 6.5mm.
    Total length: 290mm.
    Balance: set back to 0.5cm. from the guard branch
    Weight: 265g.
    Sheath: modular tactical, from thigh or belt, in Nylon
    Notes: Numbered edition - cardboard box with Extremaratio logos and certificate - being the cutting edge in carbon steel it is advisable, in order to keep the blade in perfect condition, to protect the edge with a light surface of oil.


    As in the ancient Japanese Samurai swords.

    Rolled steel - imported into Italy by Collini Steel directly from Japanese Takefu Steel - is based on the ancient Japanese tradition in the creation of the famous Samurai swords. In fact, as early as 1100 the expert Japanese blacksmiths combined different materials together to give the Katana swords incredible cutting capabilities combined with a resistance and flexibility previously unknown. It is thanks to this revolutionary construction technique that Samurai swords have been preserved to this day, becoming one of the most fascinating objects made by man. Following this tradition applied to modern metallurgy, today we are able to have technologically advanced steels already tested and used in cutlery also by famous brands such as Fallkniven, Cold Steel, Mcusta, Kai, Sog, Zwilling, Rockstead, etc.

    Characteristics of San Mai steel: These are different types of metals bonded together to create a composite that encloses and intensifies the strengths of the metals individually taken:

     

    - Longer tool life
    thanks to the use of very high quality steels with high carbon content (VG10, CoS, Shiro) or sintered (SPG2), in the heart of the sheet (Core Steel), the blade, once hardened, achieves decidedly hardness and cutting performance higher than those achieved with the use of traditional steels.

    - Greater resilience
    built with the principle of Japanese swords, multilayer steel is difficult to break thanks to the toughness of the central steel (Core Steel) and the elasticity of the steel used for the side coating (Stainless Steel).

    - Better corrosion resistance
    the steel used for the external layers (Stainless Steel) guarantees the blade a high resistance to corrosion. The combination of the two or more materials used by Takefu Steel generates, on a galvanic level, a structure that improves corrosion resistance even on the wire.

    - Easy processing even after heat treatment
    although steel normally becomes harder after quenching, the lateral steel used in multilayer processing does not lose its softness and allows easy processing, drilling or welding even after heat treatment. For an optimal performance of the blade, cryogenic treatment is recommended.

    - Improvement of the aesthetic result
    The knives made with multi-state steel or damascus pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.

  15. ExtremaRatio - Frame Rock Titan - Blue Satin - folding knife

    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.

  16. ExtremaRatio - Fulcrum C Satin knife in San Mai V-TOKU2 - Limited Edition - knife

    Japanese steel merges with Italian excellence

    For this 2019/2020 collaboration, exclusive to Collini Cutlery, we have decided to offer a series of best sellers produced by Extrema Ratio. Knives made with the famous San Mai steel produced by the Japanese Takefu Steel. Specifically, for the central sheet we used the carbonaceous V-Toku2 at 62 / 63HRC and the stainless SUS410 for the two external sheets, in order to guarantee a very high cutting, penetration and sealing capacity of the wire together with an ease of regrinding and maintenance but at the same time the blade has a remarkable resistance to corrosion and an important increase in resilience given by the type of foreign steel and the laminated structure.

    FULCRUM C model: for this First Production Run, a circulation of 10 pieces numbered from 1 to 10 was produced.

    FULCRUM C is the compact version of FULCRUM, it maintains all the characteristics of solidity and robustness and, thanks to the reduced dimensions of the blade (only 110 mm) and the handle, it is easily portable and concealable. The rigid sheath can be positioned horizontally, vertically or in a 45 ° inclined position. The only safety of the sheath is automatic with extraction and re-insertion by pressure, this detail makes it an intuitive and extremely fast tool, particularly suitable for emergency use and for personal defense.

    Use: backup knife
    Blade: integral, in Japanese laminated steel (San Mai) with cutting edge in V-Toku2 (carbon) at 62 / 63HRC and external cheeks in SUS410 (stainless steel)
    Blade thickness: 6.3 mm.
    Blade length: 90 mm.
    Total length: 210 mm.
    Balancing: set back to 0.5cm. from the guard branch
    Weight: 210g.
    Sheath: ABS with Tek-Lok multiposition attachment
    Notes: Numbered edition - cardboard box with Extremaratio logos and certificate

     

    As in the ancient swords of the Japanese Samurai.

    Rolled steel - imported into Italy from Collini Steel directly from the Japanese Takefu Steel - is based on the ancient Japanese tradition in the creation of the famous Samurai swords. Already in 1100 the expert Japanese blacksmiths in fact combined different materials to give the Katana swords incredible cutting capabilities combined with a resistance and flexibility previously unknown. It is thanks to this revolutionary construction technique that the swords from Samurai have been preserved to the present day becoming one of the most fascinating objects made by man. Following this tradition applied to modern metallurgy, we are now able to have technologically advanced steels already tested and used in cutlery also by famous brands such as Fallkniven, Cold Steel, Mcusta, Kai, Sog, Zwilling, Rockstead, etc.

    Characteristics of San Mai steel: These are different types of metals bonded together to create a composite that encloses and intensifies the strengths of the metals taken individually:

     

    - Longer tool life
    thanks to the use of high quality steel with a high carbon content (V-Toku2, VG10, CoS, Shiro) or sintered (SPG2), in the heart of the sheet (Core Steel), the blade once hardened, reaches hardness and cutting performance significantly higher than that achieved with the use of traditional steels.

    - Greater resilience
    built with the principle of Japanese swords, multilayer steel is difficult to break thanks to the toughness of the central steel (Core Steel) and the elasticity of the steel used for the lateral coating (Stainless Steel).

    - Better corrosion resistance
    the steel used for the external layers (Stainless Steel) guarantees the blade a high resistance to corrosion. The combination of the two or more materials used by Takefu Steel generates, at the galvanic level, a structure that improves the corrosion resistance also on the wire.

    - Easy processing even after heat treatment
    although normally the steel becomes harder after hardening, the lateral steel used in multi-layer processing does not lose its softness and allows easy processing, drilling or welding even after heat treatment. For optimum performance of the blade, cryogenic treatment is recommended.

    - Improvement of the aesthetic result
    The knives made with multistate steel or with damask pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.

  19. ExtremaRatio - Nimbus Special - Collector's Edition - Knife

    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.

  28. ExtremaRatio - Shrapnel OG Satin in San Mai CoS - knife

    For this new exclusive collaboration with Extrema Ratio we decided to propose a best seller in the world of cutlery, the Shrapnel model. It's a satin blade version but the most important thing is that has been used, for the first time in Italy, the famous Japanese Steel San Mai produced by Takefu Steel. Specifically, we used the CoS (Cobalt Special, considered mechanically superior by 25% compared to the already appreciated VG10) for the central plate and the 420J2 (55 HRC) for the two side plates, in order to have a high cutting capacity, but at the the same time a remarkable resilience and resistance to oxidation.

    A First Production Run of 30 pieces has been made.

    SHRAPNEL OG is a truly versatile “back up” knife with marked combat qualities. Its leaf-shaped blade is flat ground at a characteristically low angle to a wide, extraordinarily sharp edge. The included hard sheath can be worn vertically, horizontally or obliquely (at a 45° angle). Tthe SHRAPNEL OG hilt design does not include a guard.

    Use: tactical , sports , hiking , collection
    Blade: Full , Japanese- rolled stainless steel ( San Mai) with sharp CoS to 61,7HRC in cryogenic tempering
    Handle: Forprene
    Blade length: 90mm.
    Blade Thickness: 6.5 mm.
    Overall length: 210mm.
    Balancing: back to 0.5cm . by guard branch
    Weight: 214g.
    Sheath: ABS with Tek - Lok multi attack
    Notes: cardboard box with Extremaratio logos and certificate


    Clad Metal
    It is a composite metal partly or entirely diffusion bonded together of different kinds of metals.

    Metal composition shows higher performance which respective materials alone do not possess and the performance complements opposite characteristics of each material, that is "compound characteristics"

    Clad Effect on Cutleries

    Toughness
    Like Japanese swords, clad metal is hard to break or bend, thanks to the toughness as the hard steel part is clad with soft steels.
    Easy to work on
    Cladded structure is easy to apply on such works as forging, grinding, sharpening or polishing to make a sharp blade.

    Improved corrosion resistance
    Proper material combination generates electrical potential difference and it enhances the corrosion resistance on blade edge.

    Better and long lasting sharpness
    Steel after forging pressure makes the microscopic structure denser and improves the sharpness and ensures long lasting performance.

    Resource saving
    As high class steel is used only for necessary part, it is perfectly cost effective..

    Easy distortion correction
    As the steel is bonded with soft steel materials, its blade is hard to break and the distortion correction is easy.

    Easy drilling and welding after heat treatment
    Though the steel gets harder after heat treatment, the soft steel never loses its softness, enabling the material to be drilled or welded.

    Design improvement
    Laminated patterns or Damascus patterns appear from basis materials which are bonded with different kinds of metals.

  38. ExtremaRatio - Culter Venatorius - Limited Edition - Hunting Knife

    Extrema Ratio is proud to present the Culter Venatorius that, so as not to contradict the current address is a technical knife, practical, perhaps a bit 'specialized and that gives a nod to tradition and to the tastes of the most traditionalist hunters who like to do everything yourself.

    The Latin motto engraved on the blade reads:

    "I am the hunting knife, I am the claw beak and fang of my master. My job is as old as the flesh and blood.", We find that describes significantly the pure essence of the instrument.

    We feel to say that if a tool could be capable of humor probably would have added: "It 'a dirty job ... but someone has to do it ...".

    The Culter Venatorius, more than a knife, is a complete equipment for slaughtering and skinning of medium and medium-large sized prey, suitable for ungulate hunters.

    The kit includes: a knife to slaughter and general use, one skinner provided with cross handle to skin and clean the internal organs the animal, a carver to skin head and snout and a stone with two grains for regrinding of all instruments.

    These accessories are contained in the sleeve pocket leather fat-crafted.

    The sheath while maintaining the traditional lines, is completely reversible (both the pocket that the passer can be disassembled and applied on the other face of the sheath) and to secure the side which holds the knife has the ambidextrous release. The sheath is handmade by a master saddler leather first-aged choice.

    And 'possible to bring the sheath is vertical to the belt connected to the leg, which in a comfortable horizontal position, the shoulder or stopped at the waist with a long belt kit with buckle and snap hooks.

    The handle in cocobolo oiled is long enough to allow the use of the knife as a little machete or chopper and thin enough to allow precision cuts.

    The blade is in the classic Bohler N690, an excellent steel chrome molybdenum vanadium and cobalt which deserved to become a standard in technical and professional cutlery.

    The finish is satin.

    The Culter Venatorius is dedicated to all those who wish an Extrema Ratio as batting partner.
