Abstract (en)
[origin: US2022324251A1] The present disclosure provides a pencil sharpener for pencils having a lead surrounded by a lead carrier. The pencil sharpener includes a hollow guide channel for the pencil to be sharpened. An inner surface of the guide channel forms a guide surface for a partial area of a lead carrier of the pencil to be sharpened. To prevent contamination of an outer surface of the lead carrier the inner surface of the guide channel is interrupted by at least one cleaning groove extending in an axial direction of the guide channel.
