A device for cutting a sheet rock panel. A base plate has a through slot that receives a blade of a conventional utility knife and a free end right angle metal end clip of conventional tape ruler and a blind slot that receives the conventional tape ruler. A clamping plate is displaceably attached to the base plate and clamps the conventional tape ruler between itself and the base plate. The clamping plate has a center portion that is circular-shaped and a portion that has a concave upper surface and a convex lower surface that clamps the conventional tape ruler in the concave blind slot in the base plate.

Sheetrock panel cutting device

A sheetrock panel cutting device that is attachable to the end of a conventional metal tape ruler and uses that same tape ruler to not only measure the opening but to also guide the cut of a sheetrock panel while accomplishing both these functions without removing the tape ruler therefrom. A utility knife is inserted into a preformed slot in a base plate which causes the blade of the knife to be aligned juxtaposed to the right angle clip of the tape ruler. The blade protrudes through the base plate and which is directly mounted against the right angle ruler end clip. The device is used to cut a rectangular panel of sheetrock of predetermined size from a full sheet by holding the utility knife, which is positioned in the device, against the sheetrock paper surface with one hand while grasping the metal tape ruler surface, at a previously measured position on the tape, with the other hand against the edge of the sheetrock panel. Once positioned, the workman draws both hands in parallel motion across the surface of the panel, pressing the utility knife into the surface of the sheetrock with one hand and thereby causing the blade of the knife to cut through the sheetrock paper covering, while maintaining contact with the measured position of the ruler against the edge of the sheetrock panel with the remaining hand.
