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/lever tip to dig into some shells. Be prepared for adventure with a sturdy cutting tool on hand. 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 water adventure. Quick-drain sheath mounts virtually anywhere with removable belt clip, 1-inch strap holder, and lanyard holes. Instantly access your knife with the quick-release sheath, simply press the thumb tab or pull firmly on the knife. Full-tang blade with bottle opener and rounded tip.
