Abstract: A multipurpose ski apparatus is presented which may be used to tune and groove a ski. The apparatus may be easily held by a person's hand. It has a file on its upper end for filing the bottom side of a ski, a metal scraper for scraping the bottom of the ski, two rotating blades coupled to its bottom surface for filing the sides of the ski, and a removable insert which may be placed into an aperture in the bottom surface for grooving a layer of wax applied to the bottom surface of the ski. The multipurpose ski apparatus may be used without a vise or any other anchoring device. A method for tuning a ski with the multipurpose apparatus is also presented which comprises the steps of scraping the wax off the bottom surface of the ski by the metal scraper, filing the bottom surface of the ski with the file fastened to the top end of the apparatus, and simultaneously filing the sides of the ski with the two rotating files.
