Sea Harvester Dive Knife 5.5 Inch Blade Durable 420 Stainless Steel with Quick Release for Divers

Dive Knife 5.5" Blade - Durable and Versatile Tool

Designed for divers, fishermen, and coastal explorers, this Sea‑Harvester dive knife combines rugged reliability with practical versatility. The 5.5" straight edge blade, crafted from tough 420-grade surgical stainless steel, delivers clean slicing for seafood preparation and dependable cutting power in emergencies. A serrated saw edge complements the straight blade for rope, kelp, and tougher materials you encounter underwater, making it a true all‑in‑one tool for underwater tasks.

One‑handed operation with instant access. The quick release button lets you deploy the knife swiftly, so you can react fast when time matters. The secure lock‑up ensures the blade stays firmly in place during use, while the large finger guard enhances safety in challenging conditions.

Ergonomic, purpose-built design. The moulded handle features a hammer head and tank banger for quick taps or light taps against hard surfaces, plus a comfortable rubberised grip that remains secure even when gloves are wet. A dedicated lanyard hole keeps your knife tethered to you or your gear, reducing the risk of loss in currents or turbulent water.

Complete underwater toolkit in one package. This kit includes a rugged molded plastic press snaplock sheath and two leg straps, giving you flexible carry options—on your thigh or attached to your buoyancy device—so you can stay streamlined and ready without fumbling for gear.
