Scuba Diving Knife

Diving knives are mostly made of stainless steel, but some are made with other metals such as titanium. It is important to keep them sharp as they are designed to ensure that divers can free themselves in emergencies when every second counts.

Since they are intended to be submerged and in contact with water, their sharpening must be well done to minimize galvanic corrosion. Clean stones free from dust or iron residues should be used.
