Did Leonardo da Vinci invent scissors?

Revealing myth between da vinci and the scissors.....





Leonardo da Vinci is popularly, but erroneously, 
credited with inventing modern scissors. 
A scissor-like tool made of a single piece of metal was in use in ancient Egypt
around 1500 BC. There is evidence of modern cross-blade scissors with a pivot being used
in Rome some 1600 years later. Quite simply, Leonardo da Vinci did not invent scissors.
He was born long after examples of Roman scissors were found.
