C4 Naifu Spearfishing Knife | The Ultimate Underwater Tool

Elevate your underwater adventures with the C4 Naifu, the definitive spearfishing knife engineered for the discerning diver who demands safety, performance, and unwavering reliability. Designed and crafted by the experts at C4, the Naifu is more than just a cutting tool; it is an essential piece of equipment for every spearfisherman, freediver, and scuba enthusiast. Its intelligent design ensures it is ready for any situation you might encounter beneath the waves, from routine tasks to critical emergencies.

Unmatched Versatility and Performance

The C4 Naifu is built to be the most versatile tool on your dive belt. The high-performance blade is ingeniously designed with a dual-profile edge to handle a multitude of tasks with precision and ease. One side features a razor-sharp straight edge, perfect for making clean, precise cuts, preparing bait, or dispatching your catch humanely. The opposite side is equipped with a powerful serrated edge, designed to saw through tough materials like rope, monofilament, and tangled fishing nets, ensuring you can free yourself or your gear in a critical situation. This dual-functionality means you are prepared for anything without needing multiple tools.

Superior Grip, Control, and Safety

In the challenging underwater environment, a secure grip is non-negotiable. The Naifu features a highly ergonomic, overmolded handle that fits comfortably in your hand, providing exceptional control and preventing slippage, even when wearing thick neoprene gloves. The handle’s distinct shape and texture ensure a firm, confident hold, allowing you to apply force accurately and safely. Furthermore, the integrated hilt protects your hand from sliding forward onto the blade during forceful piercing or cutting actions, adding a crucial layer of safety to its design.

Instant Access with a Secure Locking Sheath

When you need your knife, you need it immediately. The C4 Naifu comes with a robust, low-profile sheath featuring an innovative quick-release locking system. This system allows for effortless, one-handed deployment—a simple, intuitive press is all it takes to release the knife. Just as importantly, the knife locks back into the sheath with a secure, audible "click," giving you the confidence that it will not be accidentally lost during a dynamic dive, navigating through kelp, or entering and exiting the water. The sheath includes durable straps, offering versatile mounting options on your belt, arm, or leg for customized and convenient access.

The C4 NAIFU is a belt knife with a total length of 204mm and a blade length of 94mm, striking the perfect balance between a compact, unobtrusive profile and a long, functional blade. A standout feature for every spearo is the integrated shaft extractor—a precisely machined hole in the blade designed to provide leverage for freeing stuck or bent spear shafts from rocks or a powerful fish. This simple yet invaluable addition can save a dive and your expensive equipment.
