ABSTRACT:
A shingle cutter for cutting a substantially straight even edge on a shingle includes a base with a work surface for supporting the shingle during cutting. A blade with a substantially straight cutting edge and a handle is pivotally attached to the base. The pivotal attachment includes a bearing and a lock nut disposed on a threaded rod or pivot arm, which keeps the blade tight against a support member recessed in the base. A guide member having a raised edge is positioned on the work surface of the base for aligning the shingle to be cut. The blade and the support member are formed of an angled piece of material for providing additional strength while cutting through the thickness of the shingle. The base is attached to legs for elevating the base above a supporting surface. A pad, which may be formed of a non-skid material, is attached to the legs for preventing the shingle cutter from sliding down the roof. A safety mechanism is provided for preventing movement of the blade during non-use of the shingle cutter.
