At right-angles to the bottom plane of the profile extends a longitudinal, downwardly open track (3) for grinding material (4). The profile also has a longitudinal, downwardly open U-shaped channel (7) running parallel to the track (3). - In this channel (7) is fitted a support which is adjustable as to height, for location against the under side of the ski, allowing the grinding angle to be varied. |
