Knife withdrawn from a private collection - Model FULCRUM T Used overall in good condition. It has numerous scratches on the blade - Checked, sharpened and certified by our in-house Coltelleria Collini laboratory.

After the Shrapnel, Extrema Ratio gives us a second knife which, despite having a total length of only 21 centimeters, maintains all the technical / tactical characteristics of the previous models unaltered.

The Fulcrum C (compact) therefore completes the fixed blade Fulcrum series and turns out to be a sturdy and compact knife, suitable for emergency or concealed use.

N690 58HRC steel blade with testudo coating
Blade thickness: 6.3 mm.
Blade length: 110 mm.
Total length: 210 mm.
Handle: in Forprene
Sheath: rigid ABS with Tek-Lok coupling with automatic knife retention system.

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 Compact model: for this First Production Run a run of 10 pieces numbered from 1 to 10 was created.

The lethality of the COL MOSCHIN knife in compact version. Supplied with rigid belt sheath and BELT-CLIP. The rigid sleeve can be positioned horizontally, vertically or in a 45 ° inclined position

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: 110mm.
Blade thickness: 6.5mm.
Total length: 212mm.
Balance: set back to 0.5cm. from the guard branch
Weight: 209g.
Sheath: ABS with multi-position Tek-Lok attachment
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 thin 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.
