Abstract: A device for determining level of a surface, the device comprising a plurality of level vials configured to indicate orientation of the device, the plurality of level vials disposed at distinct locations on the device. The device including a radius bottom formed in an object contact surface at substantially the latitudinal center of the contact surface and extending longitudinally the length of the surface. The device further including a joint recess disposed centrally along the longitudinal axis of the device and extending latitudinally across the device. The device also includes one or more user controllable light sources coupled to the plurality of level vials for illuminating the level vials.

Abstract: In embodiments, an apparatus for sharpening the edges of the ski/snowboard is provided. The apparatus may sharpen the edges of the skies without scratching the ski base. The apparatus may include a file support having holes for affixing a file. In addition, a radius base plate having a curvature is attached with the file support at right angle. In embodiments, the curvature of the plate from the tip to the tail may be symmetrical or asymmetrical and the angle between the file support and the radius base plate may vary between 90 and 96 degrees.

Abstract: The present invention provides a handle for transferring rotary motion from a rotary tool to a rotary-oscillating attachment, for converting a rotary tool to a remote oscillatory tool. The handle attaches the rotary-oscillating attachment to a rotating drive shaft of the rotary tool through a flexible shaft.

Abstract: The present invention comprises a tuning device for providing a desired operative edge of a tool or any item wherein a certain operative edge surface is desired. Whether for a new snowboard or ski, or for situations where these items no longer possess the operative edge surface desired, the present invention restores or creates a desired edge quickly with minimal effort. The present invention may include a base, a motor with attached tuning bit and at least one magnetic member designed to achieve a desired distance between the tuning bit and the tool or item being sharpened. By means of the attractive forces created by the magnetic member, the device of the present invention may travel in the same axial direction as that achieved by the rotation of the tuning bit. Although it is preferable for an operator to maintain control of the device at all times during operation, the magnetic forces utilized would ostensibly allow for substantially hands-free operation of the device as desired.
