Japanese 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.

Born from the growing demand of demanding professionals, Extrema Ratio presents ONTOS—a field knife designed to tackle any challenge. The name, derived from the Greek word for “the thing,” represents the perfect synthesis of strength, versatility, and reliability. Compact but extremely durable, ONTOS is the ideal companion in any situation, thanks to its partially serrated blade that always guarantees a sharp, ready-to-use cut.

Its nylon thigh sheath, equipped with the MOLLE system, is designed to remain firmly anchored even in the most difficult conditions, when the soldier is forced to give up his primary tactical equipment.

The “Extrema Ratio Sethlans” is a fixed blade utility knife designed to handle a wide range of situations, suitable for survival, bushcraft, prepping, but also as a backup blade. The Sethlans is available in two versions with two different types of steel.

The Black version uses D2 steel, heat and cryogenically treated to 60 HRC, which has a high regrindability even with makeshift tools. To give greater hardness and resistance, the blade is coated with the new Teflon-based product “EXP DARK” offered by Extrema Ratio.

The knife comes with G10 scales featuring the ergonomic design characteristic of Extrema Ratio handles. They can be removed to reveal the skeletonized structure of the knife, which allows for maximum lightness with minimum thickness. For lovers of extreme customization, the full-tang structure allows the handle to be coated with paracord.

The sheath is made of a lightweight, minimalist Kydex. It can be disassembled and adapted for both left- and right-handed users. The addition of an optional belt clip allows the knife to be positioned either vertically or horizontally and makes the sheath much more versatile than the textile version. It also comes with a mini pouch with a M.O.L.L.E. system containing a double-sided sharpening stone and a firesteel for lighting fires.

As in the ancient Japanese Samurai swords.

The rolled steel - imported into 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. 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 life of the cutting edge
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, at the galvanic level, a structure that improves the corrosion resistance even on the wire.

- Easy processing even after heat treatment
although steel normally becomes harder after hardening, 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 with a damascus pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.

Japanese steel merges with Italian excellence

For this 2019/2020 collaboration, exclusive to Coltelleria Collini, we decided to propose a series of best sellers produced by Wander Tactical. 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. 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.

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 damascus pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.
