More on Z-Knife

Their small size, protected blade, and ergonomic shape make them ideal for fast, safe use underwater. Unlike traditional knives, Z-Knives are less likely to cause injury or snag on gear. Many divers carry them as a backup cutting device attached to a harness or BCD for entanglement emergencies.
