The scraper arm (3) is formed by a U-shaped beam (7, 8) with at least one of its flange surfaces forming an upwards-facing scraper edge. The arm is pivotably secured at one end to a fastener (4) removably mounted at the bottom end of the ski stick. A mounting (9) forms the connection between the stick and arm and is pivotable about a hinge pin (5). A stop (6) cooperates with the mounting to keep the arm at right angles to the stick. |
