ABSTRACT:
A snow scraper attached to a ski pole shaft includes an elongated member having an exterior surface and a wall. The ski pole shaft extends through a longitudinally oriented, cylindrical channel in the member. The member has a substantially planar exterior surface portion oriented tangentially to the channel and spaced outwardly from the channel. A radial slot extends from the channel perpendicularly toward and intersects the substantially planar exterior surface portion. Two longitudinally extending edges are defined by second and third exterior surface portions that intersect with the substantially planar exterior surface portion. Inwardly concave, exterior surface portions are located between the edge and the channel in the sidewall of the member. A means for clamping the member to a ski pole shaft is also included.
