Abstract: A sanding appliance is described for supporting a sheet of sandpaper. The appliance includes a sanding pad with a flat lower sandpaper supporting surface of triangular outline. The pad is formed from sheet material which includes three edges defining the periphery of the sheet. The edges intersect at three points and a handle is connected to the pad for supporting and controlling the movement of the sander. The pad includes beveled surfaces at its edges which are inclined obliquely upward proceeding toward the center of the pad for supporting the edges of a sheet of sandpaper which are folded upwardly and centrally around the peripheral edges of the pad.
