Abstract: A combination hand tool for use in the construction and finishing of interior wallboard panels in the construction trade, provides a utility knife for cutting and scoring of the board to the desired dimensions, a rasp or file surface for smoothing the cut edge of the wallboard, and a smoothly rounded handle end for use in tamping or burnishing the cut paper edge of the wallboard. The combination tool eliminates need for additional tools for the job, and enables the user to provide more smoothly finished edges to substantially reduce the time and materials otherwise required in applying tape and joint compound to relatively rough or unfinished edges. The tool is preferably formed of relatively durable materials, i.e., aluminum or stainless steel for corrosion resistance and long life, and is configured to accept standard utility knife blades.
