ZooKeeper Titanium Dive Knife

Elevate your dive kit with the all-new ZooKeeper Titanium Dive Knife — the ultimate multi-tool for serious scuba divers, lionfish hunters, spearfishers, and marine conservationists. This premium titanium blade is engineered for relentless performance in the harshest saltwater environments while doubling as a powerful ally for reef and pier debris cleanups. Crafted from high-grade titanium, the ZooKeeper Dive Knife outperforms traditional coated stainless steel knives in every way. Titanium is completely rust-proof and corrosion-resistant, 45% lighter than steel, stronger against bending, holds a sharper edge longer, and requires virtually zero maintenance — perfect for frequent divers and international travel. Available in Two Mission-Ready Sizes: Compact Option: 3.5″ blade (7.5″ total length in sheath) — ideal for everyday carry and quick tasks. Heavy-Duty Option: 4.375″ blade (8.75″ total length in sheath) featuring a built-in line cutter for demanding jobs. Both models deliver versatile cutting power with a razor-sharp straight edge and serrated section, making quick work of ropes, fishing line, monofilament, nets, kelp, tangled marine debris, and invasive lionfish. Whether you’re on a lionfish hunt, clearing abandoned gear during a reef cleanup, or handling emergency situations underwater, this knife is built to perform. Innovative Safety Sheath System Squeeze both sides of the sheath simultaneously to release the blade — it will not open if only one side is pressed, preventing accidental deployment. Simply push the knife back in for a secure snap-close lock. The durable black sheath includes a rubber adjustable strap for secure attachment to your BCD, leg, wrist, or belt. Why Choose ZooKeeper?
