When you are deep underwater, having a reliable, fast-access blade can be the difference between a successful dive and a critical situation. The Mac Coltellerie Sub 11D Dive Knife delivers premium Italian craftsmanship directly to your dive kit, offering a razor-sharp edge right when you need it most. Whether you are freediving, spearfishing, or managing lines on a boat, this stiletto-style blade is engineered for ultimate underwater reliability.

Italian Craftsmanship Engineered for Harsh Australian Marine Environments

Crafted in Maniago, Italy—the world's capital of elite blade-smithing—this premium scuba diving knife is built to withstand relentless saltwater exposure. Featuring an 11 cm double-edged blade with both straight and aggressively serrated edges, it allows you to effortlessly slice through heavy monofilament, anchor ropes, or kelp with absolute precision. The high-visibility yellow contoured handle ensures you never lose your grip in cold waters, while the innovative O-ring sheath system guarantees secure, one-handed deployment even when wearing thick neoprene gloves.

• Italian-Made Stiletto Blade: Crafted from marine-grade stainless steel to resist saltwater corrosion while maintaining a razor-sharp edge.
• Dual-Edge Versatility: Features a razor-straight edge for precise slicing and a serrated edge to quickly saw through tough marine ropes.
• High-Visibility Handle: The vibrant yellow contoured grip is easy to locate underwater and offers ergonomic control in wet conditions.
• Lanyard Attachment Point: Features an integrated lanyard hole in the handle to prevent accidental loss during deep reef descents.
• Secure O-Ring Sheath: The impact-resistant plastic scabbard holds the knife firmly in place with an O-ring lock for rapid, one-handed release.

This is the ultimate low-profile safety tool for spearfishing and scuba diving in high-current environments. While bulkier utility tools are great for heavy-duty commercial work, this streamlined stiletto is designed for rapid, snag-free deployment when every second counts. During our field testing off the rocky Southern reefs, we found the high-vis yellow handle exceptionally easy to spot in low-light conditions, and the O-ring tension holds incredibly secure even when battling heavy ocean swell. If you want a dependable, Italian-made blade that perfectly balances safety, cutting power, and effortless deployment, add this to your dive rig today.
