ExtremaRatio - K-Talon Karambit - N690 Dark Stone Washed - Knife
The K-Talon is a karambit with a particularly thin full tang structure that, including sheath and grips, reaches a thickness of only 10 mm. The curved, hooked blade is designed inspired by the shape of a claw. It is designed to achieve precise, deep cuts while simultaneously hooking, trapping and/or ripping.
The back ring is designed to achieve a strong and secure grip in all conditions preventing the knife from sliding back and making it exceptionally difficult to disarm or turn against the user.
The very thin Kydex sheath has a quick release and comes with paracord that allows it to be used as a neck knife or attached to MOLLE-system platforms.

ExtremaRatio - Satre - N690 Black - Neck Knife - Knife
Satre is a small, light and extremely resistant fixed blade knife. Given its characteristics, it is used in a wide range of disciplines and uses ranging from survival activity, bushcraft or as an element of an EDC (Every Day Carry) kit.
It was designed in collaboration with Daniele Dal Canto, Master Advanced F.I.S.S.S. (Italian Federation of Sports and Experimental Survival).
In Neck Knife mode, through the use of a paracord 550 cord, it is possible to keep it around the neck by keeping the knife vertically 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 skeletonized structure allows you to customize the knife using paracord as a coating for the handle
This Black version uses the Böhler N690 heat treated at 58 HRC. This material is chosen for its resistance to oxidation, the durability of the wire and above all the reliability it has shown over the years.

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.

Satre Expeditions, as well as the Satre model from which it derives, 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 or as part 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 skeletonized structure, allows you to customize the knife using Paracord as a coating for the handle.
Satre Expeditions uses Böhler N690 steel heat treated to 58 HRC with MIL-C-13924 burnishing and stone washed surface treatment (Dark Stone finish). It comes with a desert-colored pre-formed kydex sheath on which you can attach the Firesteel for lighting fires (provided inside the box).

ExtremaRatio - N.K.1 Neck Knife - SanMai V-TOKU2 - Limited Edition - NK1 - Knife
Japanese steel merges with Italian excellence
For this 2021 collaboration, exclusive to Coltelleria Collini, 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 have used the carbonaceous V-Toku2 at 62/63HRC for the central plate and the stainless SUS410 for the two external plates, in order to guarantee a very high cutting capacity, penetration and edge holding together with an easy resharpening and maintenance but at the same time the blade has a remarkable resistance to corrosion and an important increase of resilience given by the type of extreme steel and the laminated structure.
Intended Use: Neck Knife / Collector's Knife
Type of production: Industrial
Country of Production: Italy
Blade / Handle: Full, laminated Japanese steel (San Mai) with V-Toku2 (carbonaceous) cutting edge at 62/63HRC and SUS410 (stainless steel) outer cheeks
Blade finish: Satin finish
Blade length: 40mm.
Blade thickness: 3mm.
Total length: 129mm.
Weight: 55g.
Sheath: Kydex, for neck.
Packaging: Cardboard box with Extrema Ratio logos.
Notes: Numbered edition - cardboard box with Extremaratio logos and certificate - the central core of the blade and handle is made of carbon steel so it is recommended to wash/dry the knife very well after each use and protect the steel, during storage, with a light surface of lubricant to avoid rust and oxidation.As in the ancient swords of the Japanese Samurai.
The rolled steel - imported in Italy by Collini Steel directly from the Japanese Takefu Steel - is based on the ancient Japanese tradition in the creation of the famous Samurai swords. As early as 1100, expert Japanese blacksmiths combined different materials to give Katana swords incredible cutting capabilities combined with previously unknown strength and flexibility. It is thanks to this revolutionary construction technique that the Samurai swords have been preserved until our days 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: It is made of different types of metals alloyed together to create a composite that contains and intensifies the strengths of the metals individually taken:
- Longer cutting edge life
thanks to the use of high quality steels with a high carbon content (VG10, CoS, Shiro) or sintered (SPG2), in the core steel, the blade, once hardened, reaches hardness and cutting performance decidedly superior to those achieved with the use of traditional steels.- Greater resilience
Built on the principle of Japanese swords, the 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).- Improved corrosion resistance
The steel used for the outer layers (Stainless Steel) gives the blade a high resistance to corrosion. The combination of the two or more materials used by Takefu Steel generates, at a galvanic level, a structure that improves corrosion resistance even on the edge.- Easy machining even after heat treatment
Although steel normally becomes harder after hardening, the lateral steel used in multilayer machining does not lose its softness and allows easy machining, drilling or welding even after heat treatment. For optimum blade performance, cryogenic treatment is recommended.- Improved aesthetic performance
Knives made of multi-state steel or damask pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.ER-NK1-CC -
