ABSTRACT:
A sharpener includes a sharpener body, a guide collar and a shaving blade. The guide collar has an oval bore defining a pencil-guiding channel and is mounted on the sharpener body such that it can be rotated essentially about the axis of the pencil-guiding channel. The shaving blade is fastened on a blade holder of the sharpener body to be positioned axially offset in relation to the guide collar and obliquely in relation to the axis of the pencil-guiding channel. A concave guide contour, into which the shaving blade projects by way of a cutting edge is formed on an inner surface of the blade holder adjacent to the pencil-guiding channel. When the pencil positioned in the pencil-guiding channel is rotated in relation to the sharpener body, the axis of the pencil-guiding channel is guided on an essentially oval path in relation to the cutting edge.
