★★★★★ What are Blunt-Tip Scissors and what are they used for?

Blunt-tip scissors are a hand tool used for cutting 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 gripping and maneuvering with the thumb and middle finger. The mechanism formed is a typical example of a first-class lever, where the fulcrum is located between the resistance (resistant force) and the power (motive force). The blades rub against each other in such a way that when closed, they leave no space between them, thus cutting the desired object.
