Divers Knives

Diving knives have been issued to the RAN divers and to specialist Army units.
The heavy duty knife such as the one by Siebe Gorman was on issue to various units up until the 1980's and may still be held in stores.
More recently lighter style diving knives have been used

Markings on the Knife

This example has a non magnetic blade. The blade is berylium which is highly toxic. Care should be taken not to injest dust from sharping such a knife. The knife does not carry acceptance marks.
