Apparatus for tuning ski and snowboard edges

An apparatus for supporting a sharpening tool when tuning an edge of a ski or snowboard, the apparatus comprising:

• a first tool support bar having
• a top surface,
• a bottom surface,
• a first tool support surface connecting the top surface to the bottom surface, the first tool support surface providing a first surface oriented at a first guide angle to the bottom surface, and
• a second tool support surface connecting the top surface to the bottom surface in a spaced relationship to the first tool support surface, the second tool support surface providing a second surface at a second guide angle to the bottom surface;
• and
• a wear plate detachably matable to the bottom surface of the first tool support bar, wherein the first tool support bar is matable to the wear plate in
• a first position, where the first tool support surface supports the sharpening tool at the first guide angle while the apparatus is in use with the wear plate being held against a base of the ski or snowboard;
• and
• a second position, where the bar is rotated approximately 180° about a central transverse axis of the first tool support bar, where the second tool support supports the sharpening tool at the second guide angle while the apparatus is in use with the wear plate being held against the base.
