Abstract: A hand-held sanding tool for sanding various objects is disclosed. The sanding tool includes a machined sanding block aligned with a detachable wedge-shaped part on any of its side surfaces, and a sanding belt wrapped around the machined block and the detachable wedge. The wedge-shaped part includes a rounded-side placed facing outward and a flat surface aligned with the machine sanding block to tighten the sanding belt in place. The sanding belt is used as an abrasive installed on the machined sanding block with finger grips. A high-density foam cushion is glued to another side of the machined block for expansion. The foam cushion expands to maintain tightness. Also, the detachable wedge is a pop-out wedge for easy change of belts. Further, the machined sanding block and the wedge-shaped block include a marking on any one end for indicating an upper end or top that is faced up during work.
