Diver's knife
Diver's knife is a specialized type of knife specifically designed for scuba diving and underwater activities. It is an essential tool for divers, providing a means of cutting entanglements, harvesting certain types of marine life, and as a safety tool.
Design and Features[edit | edit source]
A diver's knife typically has a stainless steel or titanium blade to resist corrosion from salt water. The blade is usually between 4 to 6 inches long, and may be straight or serrated, or a combination of both. Some models include a line cutter notch for cutting fishing line or netting.
The handle of a diver's knife is designed to be easily gripped with diving gloves on. It often includes a lanyard hole for attaching a wrist strap to prevent loss.
The sheath for a diver's knife is designed to securely hold the knife while allowing for quick and easy access. It can be attached to a diver's equipment such as a weight belt or leg strap.
Usage[edit | edit source]
The primary use of a diver's knife is as a safety tool. Divers can use the knife to free themselves or others from entanglements in fishing line, netting, or kelp. It can also be used to signal a dive buddy by tapping on a scuba tank.
In addition to safety uses, a diver's knife can be used for practical tasks underwater, such as collecting samples or harvesting certain types of marine life.
History[edit | edit source]
The use of knives in diving dates back to the earliest days of diving. Early divers often carried knives as a tool and as a means of protection against potential underwater threats. The design and materials of diver's knives have evolved over the years to meet the specific needs and challenges of underwater use.
