Modern cross blade scissors were invented in ancient Rome around 100 AD, and were used by clothes makers and barbers. The invention of scissors that can be traced back to the earliest use of the lever was first described by Archimedes around 260 BC. Scissors made of one piece of metal were most likely invented about 1500 BC in ancient Egypt. Researchers have found in ancient Egyptian ruins an early pair of scissors. Common use of scissors did not become popular until quite a bit later about the 1500s in Europe.
