The Argonaut Knife-one of the best and toughest knives-is available in a smaller version called the Argonaut Stunt. The butt, handle, hilt and blade are all fashioned out of one piece of 4mm thick 420 Stainless Steel. Then coated in black EDP, sharpened and laser etched. The handle is then wrapped, twice, in 5mm paracord and tied off with a 12.7cm (5 in.) leash. 2mm thick Kydex plastic is then heated and thermoformed around the knife to make the sheath. The sheath comes attached to a 2" belt loop and with BC mounting hardware.
The blade is available in two styles: the Spartan and the Blunt. The Spartan comes to a spear head point with one side featuring rounded die cut serrations to prevent snags on rope. The Blunt comes to a blunt chisel like tip. One full side of the Blunt blade is die cut with rounded serrations.
The handles are wrapped from the hilt to provide a spot for the forefinger and extra grip for the sheath. The butt of the handle features a sharp tactical tool and the skeleton holes in the handle are hex wrenches for emergency situations. "
