Whether you're reef diving or paddling the river, the Akua Rescue Knife easily and securely attaches to your PFD, boat deck, BCD or leg. When the situation arises, quickly release the knife and free yourself with the serrated blade, or alert your dive buddy with the rounded tank banger. The blunt tip won't puncture inflatables and works as a screw/pry point to dig into some shells. Be prepared for adventure with a rugged cutting tool at your fingertips. The 3-inch titanium-coated blade is armed with a line cutter, straight edge, and serrated edge for cutting rope, fishing line, and food. 420 stainless steel reduces rust and corrosion so you can take it on any aquatic adventure. The quick-drain sheath mounts virtually anywhere with the removable belt clip, 1-inch strap holder, and lanyard holes. Get instant access to your knife with the quick-release sheath, simply squeeze the thumb tab or pull the knife firmly. Full tang blade with bottle opener and rounded tip.
