Abstract

A shearing tool for cutting cement siding which includes upper and lower blade holders. Each blade holder has first and second ends and an elongated slot extending substantially therebetween. The blade holders are positioned so that the slots face each other and are substantially aligned. Upper and lower blades are removably mounted in the slots of the upper and lower blade holders, respectively. The upper and lower blades each have a relatively narrow cross-sectional width and a cutting edge. When positioned in the slots of the blade holders, the upper and lower blades define a cutting plane in which the cutting edges are substantially aligned and face each other. A number of links are operatively connected to the ends of the blade holders so that either the upper or lower blade holder can move towards the other in the cutting plane. The links are configured so that the cutting edges of the blades are substantially parallel upon engaging a cement siding workpiece in a closed position, and an actuator is connected to at least one of the links for moving either the upper or lower blade holders towards the other to engage the upper and lower blades with the siding in the closed position.
