It is not known precisely when this general purpose diver’s knife was first introduced, or if it is in current use.

Research suggests the Royal Navy diver's knife of a similar design was in used since before 1914. Navy regulations stated all divers and attendants must carry a knife The knives were generally carried on a frog or small loop of leather which hung from the divers belt, however some of the more specialised groups of Navy divers carried the knives in their boot as the Charioteers would. The sheath was not stamped with the maker's name whereas the blade of the knife was stamped. A similar pattern of knife was the Non-magnetic knife used by clearance divers . Both the knife and the sheath was stamped Non- Magnetic.
