Neptune Dive Knife Package

Blade Length: 3 1/8"
Overall Length: 8 1/8"
Grip: Designed for both forward and reverse grip with a universal handle fit for all hand sizes in-water.

Built for unmatched performance, the Neptune Dive Knife is a purpose-driven tool engineered for real-world maritime, diving, and self-protection scenarios. A spear-point, double-edge blade is paired with aggressive serrations and a precision line cutter to handle everything from braining fish to emergency entanglements.

Line Cutter: Integrated directly into the blade, this feature proves itself time and again in the field. It allows you to isolate and apply pressure to problem lines quickly and cleanly. Sharpened with a diamond wheel, the cutter delivers maximum sharpness and long-lasting performance—giving you one less thing to worry about when conditions get rough.

Modular Handle Scales: A calculated and feature-rich design underpins the Neptune system. The removable handle scales allow for quick rinsing and cleaning, and serve as the foundation for future upgrades. Modularity and options are key to how we continue evolving this blade’s capabilities.

Steel: CPM-S110V – U.S.-made super steel chosen for exceptional edge retention, toughness, and corrosion resistance.
Coating: NEPT-X proprietary coating adds another layer of defense, pushing corrosion resistance to the extreme for saltwater and operational environments.
