This is a razor.

It is from Egypt but the exact location is unknown. The Greek historian Herodotus wrote that Egyptian priests on duty in the temple had to wash four times a day and be clean shaven with no body hair. A razor was therefore a vital tool for a priest to meet these ritual requirements. This is a razor. It is made from a copper alloy. It is between about 3,300 and 3,600 years old, dating to the 18th Dynasty (1550-1295 BCE) in the New Kingdom.
