ABSTRACT:
A hand-held pencil sharpener is disclosed which utilizes a common double-edged safety razor blade that may be easily removed and replaced when worn. The pencil sharpener has spaced, generally parallel tapered bores of varying sizes selectively to guide pencils of different diameters against the shaving edges of the razor blade as the pencil is rotated, said razor blade being positioned between said parallel bores tangentially to place the opposed sharpened edges thereof into the bores to form the shaving edges of the sharpener.
