Patent ID: 8764522

Claim:
A single piece, hand-held dental instrument sharpening device, further comprising: a body having a planar sharpening surface and a parallel planar second sharpening surface; each planar first and second sharpening surface being substantially rectangular with a first end and a parallel second end and a first side and a second side; a uniform thickness defined by the distance between the first and second sides of the first planar sharpening surface and the second planar sharpening surface between the first end and the second end of the first planar surface; each of the first and second ends of the second planar sharpening surface extending an equal distance outwardly from the respective first and second ends of the first planar sharpening surface; a planar first end surface extending between the first ends of the first planar sharpening surface and second planar sharpening surface and a planar second end surface extending between the second ends of the first planar sharpening surface and the second planar sharpening surface, wherein the first and second end surfaces extend from the second planar surface at an equal angle within a range of 10° to 20°; a first side surface and a second side surface, the exterior dimension of each forming corresponding isosceles trapezoids; and each of said first and second sharpening surfaces having an abrasive surface such that, upon said body adapted to being held by a user in which a selected side surface abuts against a vertical edge of an elevated platform exhibiting a horizontal work surface, an uppermost arrayed of said end surfaces being maintained in an approximately parallel relationship with the horizontal work surface to facilitate sharpening of an instrument tip, an opposite of said end surfaces further facilitating sharpening of the instrument tip from a reverse edge thereof and at an identical angle relative to said body.
