Sport, Military and Collectible Knives | Coltelleria Collini

I designed the ATCF in 1986-87 inspired by my experience with military and security personnel in Central America and the United States. 

The ATCF was the first tactical knife to be fully assembled with screws instead of pins and rivets.
I invented the thumb disk to facilitate opening with both hands. This became a widely copied feature of the ATCF and is used on many other knives by manufacturers around the world.

The ATCF was the first pocket knife to use a checkering on the top which, along with the guard, provides protection and a firm grip. 

The ATCF is one of the most copied knife shapes in the knife world, and as I often like to proudly say, "The ATCF is the shape...that shaped the whole industry!"

Skinny, LionSteel's versatile new folding knife, features a SOLID billet construction and a CPM-MagnaCut steel blade.

It is opened incredibly smoothly via a flipper system supported by IKBS ball bearings, with the option of removing the flipper tab to comply with carry regulations found in some nations transforming the knife into a two-handed opening pocket knife. 

The sturdy SOLID handle is made of titanium or aluminum, with carbon fiber or micarta inserts. Both versions feature a Frame Lock type locking system and a removable and reversible pocket clip.

With this exclusive edition of Coltelleria Collini in collaboration with Fox, it was decided to combine a multi-award-winning model such as the Suru with a Japanese steel from powders (sintered) and laminated (SanMai) by Takefu Steel.

For this project we have chosen to use Super Gold2 (SPG2) steel at 62 / 63HRC for the cutting edge of the blade in order to guarantee exceptional cutting performance and duration of the sharpening, while guaranteeing at the same time a remarkable resilience and resistance to oxidation given by the lamination process of the blade.

Intended use: Sports / Collection

Blade thickness: 4mm.
Closed length: 88m.
Total length: 148mm.
Thick when closed: 11mm
Weight: 78g.
Closure: Frame Lock with stainless steel flap
Clip: flush, removable, in stainless steel
Packaging: Cardboard box with Fox Knives logos
Notes: Opening via Carson Flipper system - Movement on ball bearings - Design by Jesper Voxnaes - Aluminum version of the SURU Carbon Fiber model, winner of the Blade Show 2018 as "Overall Knife of the Year" - Exclusive version Coltelleria Collini, Sprint Run, with Japanese stainless steel by Takefu Steel SPG2 Laminate.

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.

- 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 on 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 facing (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.
