摘要： 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.

摘要： A sharpener for marking instruments such as pencils and crayons, including a blade holder with a throat having a blade mounted to engage and sharpen an inserted end of a pencil, and a squeezer having plural members extending toward the throat and resiliently biased for gripping a pencil inserted into the throat, to enable sharpening of pencils of differing cross-sectional dimensions, while inhibiting insertion of a child's finger into the throat. An external housing enclosing the holder and squeezer provides a trap to collect shavings cut by the blade and further protects fingers from the blade. A separate plastic-bladed sharpening element can be mounted on the trap opposite the blade holder to accommodate crayons.
