Located in the pocket is a rectangular stabilizing bar. The abrasive tool includes a plate sized and shaped to fit into the pockets when inserted from the central recess and having a groove formed therein for receiving the stabilizing bar. On the surface of the tool plate opposite the groove are abrasive members.
