A belt grinding apparatus is provided for obtaining maximum wear from an abrasive belt. The apparatus is particularly useful in sharpening skate blades and the like and involves a motor-driven belt arrangement in which the belt is passed over an idler pulley for guidance diagonally across the working edge of a relatively fixed platen whereby a diagonal section of the running belt substantially wider than the width of the belt is presented for grinding action against a workpiece. A movable carriage clamp is provided to hold the skate blade in grinding position and move it in a straight line against the diagonally moving belt. The platen is mounted for adjustment to accommodate skate blades of different thicknesses.
