How wide is the slingshot head?

Slingshot is a cold weapon or a game tool. Slingshot is generally made of branches in the shape of a "ya", with epithelial tendons at both ends of the upper end and a piece of skin wrapped in the body. Strength depends on the tension of the rubber band. The greater the tension of the rubber band, the greater the power of the slingshot. A long-range weapon that fires projectiles with a bow. In ancient times, projectiles were mostly used for hunting.
