Which part of the shear is known as the moving blade?

The moving blade in a shear is referred to as the thumb blade. This component plays a crucial role in the operation of shears, as it is responsible for cutting through materials when operated. The thumb blade moves toward the fixed blade, facilitating the cutting action.

In general shear design, the fixed blade remains stationary while the thumb blade (or moving blade) applies the necessary force to shear the material. It is the motion of this blade that allows for effective cutting, making it essential in achieving the desired results in various applications, whether in a workshop or industrial setting.

Other terms like "finger blade," "fixed blade," and "cutting blade" may refer to different components or functions within the shearing mechanism, but they do not accurately describe the part that moves during the cutting process. The correct identification of components within the shear is vital for understanding their operation and maintenance.
