Abstract: A cutting tool (10) adapted to produce chamfers along the edges of drywall panels. The tool (10,110,210) comprises a housing having a channel (18) defined by a base wall (13) and substantially parallel first and second sidewalls (15,17) that are substantially perpendicular to the base wall (13). A primary cutting blade (30) extends from the first sidewall (15) at an angle across the channel (18) toward the second sidewall (17). The primary blade (30) is configured to cut through an edge of a panel placed in the channel (18) as the cutting tool (10,110,210) is caused to move along the edge of the panel, thereby creating a chamfered edge on the panel. A second cutting blade (32) also extends from the first sidewall (15) and is positioned adjacent the primary blade (30) to create a perforation in the edge of the panel prior to the panel encountering the primary blade (30).

Abstract: A crimping tool capable of forming a uniform series of deformations or crimps on a workpiece, such that at least a portion of the workpiece can be modified to acquire an arcuate shape with a predetermined radius. The crimping tool includes a pair of arms and an associated pair of jaws. The tool further includes an adjustment feature associated with one of the arms for adjusting and gaging the distance between the jaws when in a crimping position. As such, the degree of deformation or crimping that can be applied by the jaws is positively limited by the adjustment feature, which physically establishes the minimum gap width between the jaws during a crimping operation. The jaws include die members specially configured to promote accurately placed and uniform crimps in a workpiece.
