Louis XVI used this razor while he was imprisoned at the Temple Prison. You can just spot the name "M. Clery" on the blade's side and Clery happened to be the King's valet who continued to loyally serve his King. Also the number "4" is engraved on the blade though it is not visible on this photo. In 1993 the relic went on display at the Musée Carnavalet in Paris. The sheathe is made of black leather edged with gold.
