A ski-sharpening and surface-renovating unitary tool consisting of a strong, rigid, one-piece handle, having a grip at each end, and having three abrading surfaces, one longer abrading surface being placed just below and at right angles to two shorter abrading surfaces whereby the longer surface and at least one of the smaller surfaces can be simultaneously utilized to renovate the bottom surface of a ski and a metal edge of a ski, respectively. All of the scraping surfaces are of hard metal and the shorter surfaces are both detachably fixed to the longer surface for removal for sharpening.
