Abstract
An improved cutter is provided for a plasterboard sheet, used in conjunction with a conventional T-square having a head and an elongated rule extending at a right angle from the head. The improved cutter consists of a mechanism for retaining a utility blade on the elongated rule of the conventional T-square in a proper position. When the head of the conventional T-square slides along one straight edge of the plasterboard sheet, the utility blade will make a score line across the plasterboard sheet, whereby a piece of the plasterboard sheet can then be snapped off.
