EXCELLENT GENERAL-PURPOSE DIVE KNIFE An old adage among divers is, it's better to have a knife and not need it, than to need a knife and not have it. At the same time, you don't want to swim around with a Samurai sword strapped to your leg. This is where the MAKO TITANIUM AND STAINLESS excels. It is compact enough to easily strap to a leg or forearm or mount on a BC, yet its large enough to hold with confidence when it's time to do some cutting. Mako knife has a 8,5cm multifunctional blade providing a conventional edge, line-cutting notch, serrated edge and bottle opener. Comes with a locking sheath with a one-hand release mechanism.
