★★★★★ What are scissors and what are they used for?

Scissors are a hand tool used to cut fabric, paper, hair, etc. They are made up of two steel blades that rotate around a common axial screw, with the cutting edges on one side and the handles on the opposite side. The handles have holes to hold and maneuver with the thumb and middle finger. The mechanism formed is a typical example of a first-order lever, in which the fulcrum is located between the resistance (resistive effort) and the power (motor effort). The blades rub against each other in such a way that when closed, they leave no space between them, thus cutting the desired object.

Who invented scissors and where?
