发明名称 Ski attachment
摘要 An attachment for mounting on the rear edge of a snow ski includes a mounting portion for securing the attachment to the ski, an extension portion extending rearwardly and downwardly from the mounting portion, a carrier portion extending rearwardly and upwardly from the exterior portion, and a blade element depending downwardly from the carrier portion. During use, the blade element penetrates a snowy surface to create a snow jet or "rooster tail" effect.
