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

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

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

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.
