How to choose this product

dive-knife

A dive knife can have a variety of configurations with a mix of features. It is made to withstand the rigors of saltwater immersion.

Applications

These knives are used by boaters and divers for cutting lines or nets fouling a propeller or trapping a diver, removing fish from a spear, overturning a rock, probing the sand and numerous other tasks.

Technologies

Such knives can have single- or double-edged blades, with pointed or blunt tip. While some few have folding blades, the vast majority slide into a plastic or rubber sheath strapped to the diver's leg or attached to the BCD. Some are equipped with a locking mechanism to prevent inadvertent loss.

Most blades are stainless steel, though titanium and chrome/molybdenum models also exist. Handles are simple prolongations of the metal blade or covered with PVC or rubber, often scored or shaped to improve grip. Other possible features include, serrations, a notch for line cutting and a scissors function.

How to choose

The knife should always be carried in its sheath. A folding knife may prove more generally useful since some locales prohibit carrying fixed-blade models in public.
