  4. ExtremaRatio - K1 Dobermann knife - XXV Anniversary - Limited Edition

    This special edition in 250 pieces, proposed on the occasion of the 25th anniversary of the brand, maintains the shape of the original, but with materials and finishes corresponding to the current production.

    The K1 is equipped with a modified spear point profile blade, characterized by a tip that combines the 40° "tanto" profile with the more traditional European one, creating a sharp but very solid hybrid which, with the false false edge, makes it particularly effective in jab. The bevel is high, allowing for a very effective cutting angle.

    The blade is immediately recognizable by the fenestration at the heel, which allows for considerable lightening without compromising its strength. It is made of Böhler N690 steel, with heat treatments that bring its hardness to 58 HRC for the best combination of edge hold and resistance. The finish is satin with flat grinding.

    The handle, in anodized Anticorodal alloy, compared to the original presents the lightening on the sides that make the Extrema Ratio knives immediately distinguishable, but maintains the arched shape and the lateral "bellies" of the K1, offering an excellent grip both in the "saber" than in the "reverse" grip.

    The terminal part of the handle curves to form a sort of hook which allows particularly easy and rapid extraction from the scabbard, while the tang protrudes from it with a triangular cusp which acts as a glass breaker with a slot which allows the knife to be equipped of lasso.

    The leather scabbard faithfully reproduces the original while maintaining both the qualities of ease and speed of extraction. The carry can take place in an upside-down axillary position, horizontally on the belt or tactically on the thigh.

    The K1 equipment is completed with a polypropylene case ‌, complete leather sheath and underarm shoulder strap.

  5. ExtremaRatio - S-Thil Black Warfare knife - XXV Anniversary Special Edition - knife

    Extrema Ratio S-THIL Black Warfare, a special version of the S-THIL model, is a backup knife with a monolithic structure machined from a single piece of 5 mm thick BOHLER N690 steel, developed in collaboration with the designer Thilo Arnd Schiller. The spear point type blade is hardened to 58 HRC in order to obtain the best balance between edge retention and strength, has a false edge in the upper part which enhances the characteristics of penetration and tip work, and is equipped with a Full length furrow flowing elegantly from blade to grip.

    The blade is milled integrally with the knife to enhance its compactness and lightness, maintaining a minimum thickness even with a profile that recalls the classic Extrema Ratio handle. This profile forms two small guards and a comfortable thumb rest in order to prevent the hand from slipping towards the blade. On the end there is a skull crusher with a diamond-shaped tip and a slot that allows you to attach a wrist strap to the knife or to equip the handle with paracord winding.

    The special Black Warfare version uses the innovative and original Geotech Camo pattern, created by laser engraving. The molded nylon sheath has been designed to be extremely flat and with very small lateral dimensions, in order to make it as compact as possible. The design of the knife makes it ambidextrous, allowing it to be inserted into the sheath with the cutting edge of the blade to the right or left. The double retention system integral with the sheath is made up of four pressure elements that work only two at a time, depending on right/left use, while in the nylon textile part there is a button that allows you to secure the knife to the sheath . The end of the sheath has a hole that allows you to expel liquids or residues inside. The possibility of applying belt clips, ulticlips, malice clips makes it extremely versatile. It is also possible to hook the sheath to the M.O.L.L.E. system. weaving the paracord lanyard.

    The S-thil Black Warfare is supplied in an IP67 certified watertight Polypropylene technical case, with pressurization valve, resistant to atmospheric agents, dust and shocks. Inside there are also the Nylon sheath, the double ULTICLIP and the double grain sharpening plate (ceramic abrasive and synthetic diamond).

  6. ExtremaRatio - Frame Rock Titan - Black DLC - 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 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.

    Extrema Ratio Misericordia Black Warfare is a version in a limited series of only 500 pieces that preserves intact all the features of the famous Misericordia model adopted by the 4th Alpine Parachute Regiment, which helped develop and test the product and chose it for its unique characteristics that make it particularly suitable for ambush combat.

    The blade is milled from Böhler N690 steel, hardened to 58 HRC for the best balance of edge retention and strength, is 118mm long, 4mm thick, and has a flat edge.

  14. 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
    Handle: Titanium, machined from solid, with integral Frame Lock closure system with removable flap and safety made of stainless steel

  16. 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.

  20. Extremaratio - Arditi Deluxe - Single-edged dagger - Limited Collector's Edition - Knife

    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 recall this important page of Italian military history with a limited celebratory series in only 100 numbered copies. This version has a satin blade and a walnut wood handle and is sold with a wooden box and leather sheath.

    ABOUT THE STEEL

    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.

    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.

  29. 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.

    Overall length: 210mm.

    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.

  32. 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.
