Which blade functions as the moving blade of shears?

The blade that functions as the moving blade of shears is the one attached to the thumb grip. In a typical pair of shears, the moving blade is designed for cutting and is raised and lowered by the movement of the thumb. When a barber or stylist applies pressure to the thumb grip, this motion causes the moving blade to engage with the stationary blade, allowing for a smooth cutting action.

The design of shears incorporates a fixed blade, which is attached to the finger grip, while the other blade's free movement is essential for effective cutting. The sharpness of the blade and the quality of the metal are important factors that contribute to the overall performance and durability of the shears, but they are not directly responsible for the functional role that the thumb grip blade plays in operation. Understanding this mechanism is crucial for proper technique and efficiency in a barber's work.
