If you want extreme grip, it’s going to cost you about $800. That’s the price of Extreme Ratio’s new Ultramarine dive knife. Ok, now breath and listen to what that gets you. The Italian-made knife features a Nylon handle that’s hand-perforated for increased grip underwater. It also has an elastic Neoprene-like sleeve to bungie-cord the knife to your hand. This lets you handle other tools without having to resheath your knife. You can even disassemble the handle to clean off salt desposits.
Ultramarine measures 12 inches overall and features a 6 inch blade with an anti-corrosive coating. It also has serrations and a large shroud cutter on one side of the blade. The knife comes with a Cordura and molded plastic sheath and a protective carrying case.
