Abstract
A sharpener contains a housing having a receiving channel for a pencil which is to be sharpened. The sharpener is intended to be seated as a protective cap, when the pencil is not in use, with a clamping fit on the pencil circumference. The clamping connection necessary for this purpose is an external clamping-force producer which can be removed manually from acting on the housing, in particular a cleaning stick, with, for the purpose of providing the clamping force, is for example a pressure-exerting lug in the form of a wedge or with an eccentric.
