I would like to discuss about the scissors. Scissors are an example of everyday technology that is very often used. Scissors used for cutting paper, wrap, hair, etc.. The greatness of scissors is to cut without consuming power, without a complicated construction. Its simplicity makes everyone liked. So, how history ..?
Historians argue, scissors found out about in 1500 BC in Egypt, is still a knife that connects two ends. Scissors-shaped blades are interlinked middle as it is now discovered by the Romans around the year 100. Centuries later, scissors "modern" first made by Robert Hinchcliffe, which is made of steel honed. And now scissors continue to grow, without much change from the basic design.
And if you've heard that Leonardo da Vinci invented the scissors, it's actually wrong .. Leonardo not find the scissors, but formulating a machine to sharpen the curvature of scissors.
Here are some pictures scissors:
