Frequently Asked Questions
Q: Is this diving knife resistant to saltwater corrosion?
A: Yes. The blade is crafted from stainless steel with a hardness of 55 HRC, which provides strong resistance to corrosion in both saltwater and freshwater environments. Rinsing with fresh water after each dive and drying before storage will further extend the blade's lifespan.
Q: How is the diving knife attached to my body while diving?
A: The kit includes two rubber leg straps and a nylon belt buckle, allowing you to securely mount the ABS scabbard to your lower leg, thigh, or BCD. The straps are adjustable and designed to stay firmly in place underwater.
Q: Is this knife suitable for cutting rope and fishing line underwater?
A: Absolutely. The stainless steel blade features a ≤ 60° blade angle optimised for clean, decisive cuts through rope, netting, monofilament fishing line, and similar materials — making it a practical tool for spearfishing, freediving, and water rescue scenarios.
Q: What is the total weight of the full kit?
A: The knife alone weighs 108g. With the ABS scabbard, nylon belt buckle, and rubber straps included, the full set weighs approximately 185g — lightweight enough to carry comfortably on any dive.
