Boye’s Cobalt Folding Knife is ideal for “harsh, humid and wet environments,” and is a great overall knife that can be easily handled and maintained. The knife is small and lightweight, measuring 7in overall with a 3in blade, and weighing only 2.2oz. It includes a folding marlinspike that nestles alongside the robust Zytel handle to create an exceptionally slim profile. The sheepsfoot blade (a pointed tip is also available) is opened using a thumb hole and can be locked easily. The knife includes a lanyard ring, as well as a belt clip, for keeping it secure when not in use. $141.20, boyeknives.com
