Neck Knives: your reliable daily companion

DICOK TS evolves the DICOK design with technical updates aimed at professional underwater use. Developed with industry experts, it is designed to ensure reliability and safety in the marine environment.

The blade incorporates a line cutter for quick action even in critical conditions. Nitrogen steel replaces the previous N690Co, offering greater resistance to oxidation and corrosion in saline environments. The new EXP Dark coating further improves protection against corrosive agents while maintaining anti-reflective properties.

The steel structure was chosen to ensure superior hardness, edge retention, and structural strength compared to titanium, essential characteristics for operational use.

Supplied with a Kydex sheath and paracord for belt attachment, MOLLE and webbing systems, and a fiberglass-reinforced nylon handle with a non-slip finish that is ergonomic and safe even when wearing diving gloves.

The pursuit of extreme speed is a timeless challenge. In the 1920s, Frank Lockhart, legendary American driver, embodied this dream. The youngest winner of the Indy 500 at just 24 years old, Lockhart chased the all-time land speed record. On April 25, 1928, in his supercharged Stutz Black Hawk, he reached 220 mph before a tire failure ended his race. His indomitable spirit lives on today, inspiring those who dare to push the limits.

SPEED DEMON was born with this same philosophy in mind. Weighing only 70g, this urban knife combines innovative design and skeletonized handle, combining style and functionality. Compact yet powerful, it tackles any challenge with a 4.4 mm thick and 80 mm long blade. Complete with a handmade Kydex sheath, SPEED DEMON is designed for ambitious, adrenaline-thirsty men.

Biographical Note:
Bud Nealy is universally recognized as one of the best knifemakers in the world. He is also known as the inventor of the MCS (Multi Concealment Sheath) system that allows the knife to be placed securely in any type of position. And it is because of these two requirements that every day hundreds of his MCS systems are used by police officers, undercover agents, S.W.A.T. and R.A.I.D. members, U.S. embassy guards, Bodyguards and Air Rangers.

Knife withdrawn from a private collection - Limited edition production in Japanese CoS steel in SanMai dating back to 2018 and no longer available - In like new condition, no marks on the blade (never cut, never resharpened) or on the handle. Supplied with handmade Kydex sheath and Wander Tactical certificate - Checked and certified by our in-house Coltelleria Collini laboratory.

In collaboration with Wander Tactical we have decided to propose their new neck knife, the Raptor model, in an exclusive version with a satin blade that uses the famous Japanese San Mai steel produced by Takefu Steel. Specifically we used, for the central plate, the CoS at 61.5HRC (Cobalt Special, mechanically considered 25% higher than the already highly appreciated VG10) and the 420J2 (at 56 HRC) for the two side plates in order to guarantee a very high cutting capacity, but at the same time a remarkable resistance to abrasion, resilience and resistance to oxidation.

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.
