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

Scissors are a hand tool used to cut fabric, paper, hair, etc. They consist of two steel blades that pivot around a common axial screw, with the cutting edges on one side and the handles on the opposite side. The handles have holes for the thumb and middle finger to grip and maneuver. The mechanism formed is a typical example of a first-class lever, in which the fulcrum is located between the resistance (resistant 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.
