ABSTRACT:
An apparatus for cutting aluminum siding or like articles includes a movable blade and a pair of fixed blades between which the movable blade is mounted to pivot. The fixed blades are each mounted on a rail that is rigidly connected to a flexible base member. An adjustment bolt is provided for exerting force between the rails. Force from the adjustment bolt causes the base member to deflect, thereby permitting the distance between the fixed blades to be varied. A second feature includes the provision of different sets of fixed blades, each configured to conform to a different type of siding. A novel movable blade is also provided.
