A shearing apparatus wherein a portion of a workpiece which projects over a table edge is sheared off by a generally vertically reciprocable blade while the workpiece is held firmly against the table by a clamping element. A viewer affords the operator an enlarged view of the workpiece in the gap between the clamping element and the blade. The viewer has a high-intensity light source which directs a beam of light at the workpiece in the gap and a reflector and lens arranged to direct to the operator the light reflected by the workpiece. A translucent screen can be provided to afford the operator a picture-like view regardless of his position.
