Over the past year we have looked at a couple of issued jack knives, tonight we turn to the Royal Navy version. This knife is quite distinctive in that it is made entirely of metal with grey grips rather than the black seen on army examples:As can be seen, at one end is a metal loop to take a lanyard and at the opposite a protruding screwdriver type blade. The knife opens out to reveal a blade and a large marlin spike for repairing ropes with:The navy’s jack knife is unusual in having a metal plate on it where the owner’s name and number can be marked:In this case the knife originally belonged to DJ Ritchie, F019317. These knives remained in use until 1983 when they stopped being issued to new recruits; this example is from the post war period as it has a steel shackle rather than one made from copper. These knives are marked at the base of the blade, but sadly I can’t make out the writing on this example.
