Every spearfisherman has this in common, their knife needs to be easy to use, and hard to lose. That's why this knife was developed alongside die-hard Gulf of Mexico spearfisherman and Gulf Coast dive shops. 
If your version of where the map turns blue is where the ENTIRE map turns blue, this knife is for you. It features a 3.5" blade, making it able to penetrate to the necessary depths of bigger fish, and a balanced G10 handle with grip flares near the base of the blade that act as your leverage points when handling a fish. The blade also has serrations along one edge for your more damage-dealing use cases. The sheath can be slid right onto a belt or strap so you can secure it to your body practically anywhere, and the knife locks into the sheath with a snug click. Simply click it out, dispatch your fish, and click it back in. There's even a lanyard cutout at the end of the handle if you prefer to tie the knife to your body as a backup.
