Discover the Uncompromising Performance of C4 Dive Knives

Elevate your underwater experience with C4, the legendary Italian brand synonymous with high-performance spearfishing and freediving equipment. Here at diveinn, we are proud to present the C4 collection of dive knives, where cutting-edge design, superior materials, and functional excellence converge. Born from a passion for the sea and engineered for the most demanding underwater environments, a C4 knife is not just a tool; it is an essential piece of safety and utility gear for every serious diver.

C4 extends its philosophy of innovation and quality from its world-renowned carbon fins to its exceptional range of knives. Each blade is meticulously crafted to serve a specific purpose, whether you are a spearfisherman in need of a reliable dispatch tool, a freediver seeking a lightweight and hydrodynamic safety device, or a scuba diver requiring a robust multi-purpose knife for any contingency. The core of every C4 knife is its blade, forged from high-grade, marine-quality stainless steel. This ensures outstanding sharpness, edge retention, and, most critically, superior corrosion resistance to withstand the harsh realities of saltwater immersion.

Experience the pinnacle of Italian ergonomic design. C4 knife handles are engineered for a secure, non-slip grip, providing confident handling and precise control even when wearing thick neoprene gloves. The profiles are often slim and low-drag, a critical feature for freedivers and spearfishers who value efficiency and minimal resistance in the water.

The collection features a variety of blade styles to suit your specific diving needs. Discover stiletto-style blades, perfectly shaped for quick and humane dispatching of your catch, a favorite among spearfishers worldwide. Many models also incorporate a serrated edge, indispensable for effortlessly sawing through tangled fishing lines, ropes, or nets—a crucial safety feature for any diver. The razor-sharp straight edge provides clean, precise cuts for more delicate tasks.

A dive knife is only as effective as its sheath, and C4 has perfected this system. C4 sheaths are designed for security and rapid access. Featuring robust locking mechanisms, they hold the knife firmly in place during the most dynamic movements, eliminating the risk of accidental loss. Yet, with an intuitive, often one-handed quick-release system, your knife is available the instant you need it. With versatile mounting options for your leg, arm, or weight belt, you can position your C4 knife for optimal accessibility and comfort.

For the dedicated spearfisherman, the freediver exploring the depths, or the scuba diver navigating wrecks and reefs, a C4 dive knife from diveinn is an investment in safety, performance, and peace of mind. Equip yourself with the precision and reliability of Italian craftsmanship. Explore the C4 knife range and find the perfect blade to accompany you on your next underwater adventure
