Scissors are examples of everyday technology that is very often used. Scissors are used for cutting paper, wrap, hair, etc. The greatness of the scissors is that it can cut without much power consuming, without a complicated construction. Its simplicity makes everyone love. So what's the history ..?
Historians argue, scissors were found about 1500 BC before Egypt, still two knives connected to the end. The interconnected scissor-shaped scissors in the middle are now found by the Romans around the year 100. Centuries later, the first "modern" scissors were made by Robert Hinchcliffe, made of sharp steel. And now scissors are growing, without much change from the basic design. And if you've heard that Leonardo da Vinci found scissors, that's actually wrong ... Leonardo did not find scissors, but formulated a machine to hone the curvature of scissors.
Very amazing!!
