Sport, Military and Collectible Knives | Coltelleria Collini

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.

VIPERA is born from the fusion between the tactical and survival worlds, combining speed of use, robustness, and precision in a knife weighing less than 100 grams. Equipped with an elongated drop-point blade with a full flat grind and narrow edge, it offers penetration, smooth cutting, and hardness up to 61 HRC. It is available in two high-performance steels, both with excellent edge retention and corrosion resistance. The ergonomic handle with integrated guard ensures maximum control in all conditions, while the ASPIS nylon sheath allows for stable and versatile carrying.

VIPERA Nitrogen (Stone Washed, HCS, Ranger Green)
This variant is designed for outdoor, survival, bushcraft, and prepping users: areas where reliability in the field, weather resistance, and maintainability are essential. Nitrogen steel maintains excellent edge retention, combined with excellent rust resistance and, above all, greater ease of resharpening compared to M390. The increased resilience makes these models more tolerant to the abuse typical of a field environment.

Technical insight into nitrogen-added steels
Nitrogen steels, or nitrogen-added steels, are alloys in which nitrogen is used as an alloying element instead of, or in addition to, carbon. Although nitrogen is less effective than carbon in hardening the martensitic matrix, it has the advantage of forming stable compounds with chromium to a much lesser extent. This allows a greater amount of chromium to be kept in solid solution, improving corrosion resistance. In addition, nitrogen contributes to the hardness and stability of the structure, giving these steels a good balance between hardness, toughness, and corrosion resistance. Compared to traditional martensitic steels, nitrogen steels can therefore offer a better combination of mechanical properties and resistance to chemicals, while maintaining good workability and sharpenability characteristics.
