Abstract
A hand-held, manually-operated, sanding tool for use with a replaceable sheet-like abrasive material, such as sandpaper, includes a base member and clamping mechanisms pivotally connected with opposed ends of the base member. The clamping mechanisms include tensioning members arranged to slidably engage angled contact surfaces provided on the ends of the base member opposite the clamping mechanisms to tighten the sheet-like abrasive material as it is installed on the tool.
