The TK15 is a marine-grade stainless steel tactical dive knife designed for scuba and diving environments. Its polished surface promotes water drainage and resists oxidation in saltwater, helping maintain edge reliability. The fixed blade offers strength and control with a 6 in / 15 cm blade and a combination of lower smooth-edge and upper serrated edge for versatile underwater cutting.

Designed for underwater use, the knife features a clip-point tip and built-in line cutter for on-site tasks. The heavy-duty handle is secured with stainless steel screws for a reliable grip in gloves, while a SCUBAPRO branded hand cover aids secure handling during scuba diving. The fiberglass-reinforced polyamide sheath is injection-molded for durability and includes nylon straps for secure attachment. Retention features—recesses in the handle matching teeth in the sheath—keep the knife securely seated even in demanding conditions. The TK15 weighs approximately 0.851 lb (0.386 kg) and measures an overall length of 11.4 in, with a blade length of about 6.1 in.
