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.

ExtremaRatio - Col Moschin Compact in San Mai V-TOKU2 - Limited Edition - PRIVATE COLLECTION - Knife

* Condition: Like new
* Available on the market: Discontinued
* Sharpening: Original
* Blade marks: None

* Box: Included
* Sheath: Included

* Inspected and Certified by our in-house labJapanese steel meets Italian excellence
For this 2020 collaboration, exclusively for Coltelleria Collini, we decided to offer a series of best sellers produced by Extrema Ratio. These knives are made using the renowned San Mai steel produced by Japan’s Takefu Steel. Specifically, we used carbon-rich V-Toku2 at 62/63HRC for the central core and stainless SUS410 for the outer layers, resulting in superior cutting performance, penetration, edge retention, ease of sharpening, and at the same time excellent corrosion resistance and increased resilience due to the laminated structure.
Model Col Moschin Compact: this First Production Run was limited to 15 numbered units, from 1 to 15.
The lethal efficiency of the COL MOSCHIN knife, now in compact version. Comes with a rigid belt sheath and BELT-CLIP. The sheath can be mounted horizontally, vertically, or at a 45° angle.
Usage: tactical, sports, hiking, collecting
Blade: full tang, laminated Japanese steel (San Mai) with cutting edge in V-Toku2 (carbon steel) at 62/63HRC and outer cheeks in SUS410 (stainless)
Handle: Forprene
Blade length: 110mm
Blade thickness: 6.5mm
Overall length: 212mm
Balance: 0.5cm behind the guard
Weight: 209g
Sheath: ABS with multi-position Tek-Lok attachment
Notes: Numbered edition - cardboard box with Extrema Ratio logos and certificate - as the cutting edge is carbon steel, it is recommended to lightly oil the blade to maintain its condition.As in ancient Japanese Samurai swords.
The laminated steel – imported into Italy by Collini Steel directly from Japan’s Takefu Steel – is based on the age-old Japanese sword-making tradition. As early as the 1100s, Japanese blacksmiths were combining different metals to craft Katana swords with extraordinary cutting power, resistance, and flexibility. This revolutionary technique allowed Samurai swords to survive through centuries and become among the most fascinating human-made artifacts. Applied to modern metallurgy, this tradition now yields advanced steels already used in knife-making by brands like Fallkniven, Cold Steel, Mcusta, Kai, Sog, Zwilling, Rockstead, etc.
San Mai Steel Features: A combination of different metals bonded together to create a composite with amplified properties:
- Greater edge retention
Thanks to high-carbon premium steels (VG10, CoS, Shiro) or powder steels (SPG2) in the core, once hardened, the blade achieves cutting performance far superior to traditional steels.
- Higher resilience
Based on Japanese sword construction, the multi-layer steel is highly resistant to breaking due to the toughness of the core and flexibility of the stainless cladding.
- Improved corrosion resistance
The outer stainless layers ensure high corrosion resistance. Takefu’s multi-metal bonding also enhances galvanic protection of the edge.
- Easy processing post heat-treatment
Despite being hardened, the outer layers retain softness, allowing easy drilling, grinding, or welding. Cryogenic treatment is recommended for optimal performance.
- Enhanced aesthetics
Multi-layer or Damascus-patterned knives are elegant, refined, and highly valued by collectors worldwide.For more information: collinisteel

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).

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.

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.For more information: collinisteel

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.

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.ERCC-SH -
