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.
The invention of scissors that can be traced back to the earliest use of the lever was first described by Archimedes around 260 BC
Modern cross blade scissors were invented in ancient Rome around 100 AD, and were used by clothes makers and barbers.
Common use of scissors did not become popular until quite a bit later about the 1500s in Europe.
Leonardo Da Vinci did not invent the scissors. There have been examples found of Roman scissors in the modern form, from long before Da Vinci lived.
Yes, he is most frequently credited for inventing scissors with two separate pieces of metal attached at a central pivot point. But, tools with a similar look and function, yet clearly a different tool, has been dated in 1500 B C, long before Da Vinci was born. They were just basically the same tool but with a different name for them.
