Abstract: A skin-file or rasp of the kind comprising a gripping handle (1) which is provided at one end with a rasp head (2), the latter removably holding a rasping foil (11) which has longitudinally extending edges (10) having inturned portions which embrace the longitudinally extending edges of the rasp head. The edges of the rasp head are thickened and are provided with grooves (6) in which the longitudinal edges (10) of the rasping foil are located, the rasp head being provided at each end with an end stop (8 and 9) to prevent longitudinal movement of the rasping foil relative to the rasp head. The rasping foil is also provided on each of its longitudinal edges with narrow, outwardly projecting portions (12) which assist in engaging or disengaging the rasping foil from the rasp head.
