Therefore, it should be apparent to those skilled in the art that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

[0030] Embodiments of the invention are described herein with reference to illustrations of idealized embodiments (and intermediate structures) of the invention. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments of the invention should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing.

[0031] FIG. 1 is a top perspective view of an exemplary system 10. The system 10 may comprise a motor 12. One or more abrasive devices 14, 16 may be connected to the motor 12. In exemplary embodiments, a first abrasive device 14 and a second abrasive device 16 are mechanically connected to the motor 12 such that the first and second abrasive devices 16 are configured to rotate or otherwise move when the motor 12 is activated. The motor 12 may be in electrical connection with a controller 11 for controlling the power supplied to the motor 12. The controller 11 may be electrically connected to a power sources such as, without limitation, an electrical outlet or a battery. In exemplary embodiments, the motor 12 is a two-way motor such that the attached abrasive devices 14 and 16 may be rotated in either direction. The controller 11 may be configured to control the speed and direction of rotation of the abrasive devices 14 and 16. In other exemplary embodiments, the controller 11 may be integrated with the motor 12.

[0032] A positioning device 20 may be provided for positioning a tool 40 for sharpening or reshaping. The tool 40 may be nippers, clippers, cuticle nippers, acrylic nippers, cuticle pushers, gel polish tools, gel pushers, toe nail clippers, or any other tool used for nail maintenance. The motor 12 and the positioning device 20 may be mounted to a common surface 22, though such is not required. The positioning device 20 may be mounted to one or more tracks 24 or 26 located on the common surface 20, though such is not required. The tracks 24 and 26 may be configured to permit vertical and horizontal movement of the positioning device 20 along the track 24 and 26, though just vertical or just horizontal movement is also contemplated. The illustrated number and orientation of the tracks 24 and 26 is merely exemplary and is not intended to be limiting. Any number of tracks 24 and 26 in any orientation is contemplated. The positioning device 20 may comprise a receiver 27 configured to receive one or more securing devices 30, 50, or 60.
