Content: of wallboard. 3. CUTTING DRYWALL
You can easily cut wallboard with a scoring or trimming knife and a 4' straightedge. You  may prefer to use a T-square for an even and straight cut (Fig. 3). Measure accurately and make marks before cutting the wallboard. Use a straightedge for accuracy, and score along your marks. Be sure to cut through the  paper and into the inner core. Hold the knife at a right angle to the board and score completely through the face  paper. The board will break easily at the point where it is scored.
