The Argonaut Dive knives are designed to be one of our best and toughest knives. The butt, handle, hilt and blade are all fashioned out of one piece of 4mm thick titanium. Then coated in black EDP, sharpened and laser etched. The handle is then wrapped, twice, in 5mm paracord and tied off with a 5” (12.7cm) leash. 2mm thick Kydex plastic is then heated and thermoformed around the knife to make the sheath. 1/8” (3.2mm) grommets are inserted and the excess material is removed with a heat knife. The final stage is laser etching a subtle Aqua Lung logo on one side of the sheath.
