ABSTRACT:
An improved drywall cutting and scoring device which can quickly cut drywall transversely, longitudinally, and at right angles, without the need for separeate measuring, marking, chalk-lining, and cutting steps. The device includes an elongated measuring bar (14), having four planar measuring indicia extending longitudinally between its opposite ends. Telescopic guide rails (22, 24) extend from one end of the measuring bar, parallel along its length in a laterally spaced relationship. A drywall panel is cut by first depressing the locking button (48) and then moving the adjustable block (10) to any selected setting. The tool is positioned on the drywall panel (68) so that the adjustable block is mounted against one edge of the drywall panel. Rollers (46) rollably ride on the face of the drywall panel adjacent the panel edge against which the associated adjustable block is adapted to slide. The device is then drawn along the drywall panel while being depressed so as to cause a razor-sharp cutting blade (66) to penetrate and cut the drywall panel to the dimension selected.
