摘要： A shingle cutting tool for cutting a shingle having a longitudinal edge, the shingle cutting tool making a cut across the shingle at a selectable angle transverse to the longitudinal edge thereof, the shingle cutting tool including a guide member, the guide member having a substantially upright surface for guiding the longitudinal edge of the shingle, and a cutting assembly, the cutting assembly being pivotally attached to the guide member and extending outward therefrom, the cutting assembly including a cutting base member, a cutting blade, the cutting blade having a cutting edge, the cutting edge opposing the base member, a reciprocating guide mechanism for guiding the cutting blade in a reciprocating fashion within a plane extending from the cutting base, and a pressure mechanism for exerting a pressure on the cutting blade to thereby bring the cutting edge into contact with the cutting base member. Alternatively, the pressure mechanism includes either a manually actuated lever mechanism or a pneumatic cylinder.
