A tool for scoring a wall covering, such as one or more thicknesses of wallpaper. The tool has circular saw blades which are clamped to the tool body. The clamping arrangement is releasable to permit each saw blade to be adjusted for the desired depth of cut or to permit each saw blade to be turned to present a different portion of its saw-toothed periphery for cutting engagement with the wall covering.
