ABSTRACT:
The present invention relates to a crayon sharpener, which comprises a cavity to which a crayon is to be inserted, a stopper with a plane at one end, a blade which is fixed at an angle corresponding to the cavity and the stopper, and a connecting shaft which has a hole in it for installing in an electric or hand-operated sharpener. This invention can sharpen crayons smoothly and quickly without easily breaking them and the tips of the crayons will not be too sharp. This invention can be used alone or installed in an electric or hand-operated sharpener as a replaceable part to sharpen crayons and is more convenient and economical to use.
