Shop Spearfishing and Titanium Scuba Dive Knives
Shop Atomic Aquatics Titanium, Mares, and many more. A dive knife is a general diving tool that scuba divers occasionally use to cut entangling fishing line or rap on their tanks to get a buddy's attention. Some items that fall under this category aren't really knives at all, but are tools designed for specific uses underwater. Dive knives are tools not weapons and should never be used to harm aquatic creatures or deface the underwater environment.
