A disc system including disc adapted to be held by the hand and moved lengthwise along an edge portion of a ski or snowboard in order to sharpen and/or bevel either a ski or a snowboard side edge or base edge is provided. The disc is held and may be rotated within at least one concentric ring to establish a number of selected angular orientations in a plane transverse to the lengthwise direction when positioned at the side or base edge portion of the ski or snowboard while in contact with the surface thereof.

A reciprocating filing tool. The reciprocating filing tool includes a housing having a first end opposite a second end, wherein a handle is affixed to the second end. A shaft is slidably disposed within the housing, and a motor is operably connected to the shaft. The motor causes the shaft to move in a reciprocating linear movement when the motor is activated. A trigger disposed on the handle, wherein the trigger activates the motor when actuated. A plurality of files are removably securable to a distal end of the shaft. A plurality of clips are disposed on an exterior of the housing and can removably receive the plurality of files therein.
