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.
