A 3rd Century CE Roman Multi-tool
Move over Victorinox and Leatherman, the Romans beat you to it by some 1700 years.
Made of silver and iron (the rusted bit at top is the iron knife) it contains a three-pronged fork, spatula (probably for cleaning ears), pick, spike and knife.
This one is held in the Fitzwilliam Museum at Cambridge University, UK.
