Abstract
Sharpening brush for pencils and mines for writing and drawing, characterized in that a razor blade held between two plates which on one or both surfaces are provided with one or more guide slots can also serve as a sharpening and sharpening blade, coordinated in a transverse or diagonal direction, the blade being changeable and held in such a way between the two plates that it is covered throughout its length and width, with the exception of those parts of the cutting edge that coincide with necklines or openings at the entrance of the grooves and that serve to grind and sharpen or to give way to the material trimmed so that a pencil or mine can be sharpened by reciprocating movement guided by the grooves, obtaining a thin and long tip or short and thicker, depending on the more angle or sharp radius that is adopted in relation to the cutting edge during the sharpening process.
