Abstract: A sharpener for sharpening a pencil, in particular a cosmetic pencil, is especially suitable, when used correctly, for producing a particularly uniform outer jacket edge in the region of the pencil tip. The sharpener includes a sharpener body, in which a pencil guide channel is provided. The pencil guide channel has a circular cone-shaped channel section and opens out in a pencil inlet opening on the outer side of the sharpener body. A paring blade is positioned tangentially to the lateral surface of the channel section. The paring blade serves to pare off a pencil tip, which includes a front lead section and a rear outer jacket section. A shaping tool cuts a shoulder into the pencil tip, the shoulder being set back in relation to a circular cone-shaped enveloping surface of the pencil tip. The shaping tool is arranged relative to the pencil guide channel to insert the shoulder into the transition between the lead section and the outer jacket section of the pencil tip.

Abstract: A compact sharpener (1) for a pencil (S), the sharpener being cost-effective to realize and being particularly suitable for sharpening a cosmetic pencil in particular, comprises a sharpener body (2) and a shaving blade (3) fastened thereon. The sharpener body (2), in turn, comprises a guide sleeve (4) and a blade holder (5) integrally formed on the guide sleeve (4), the guide sleeve (4) having a bore (6) which defines a pencil-guiding channel (7) and has an introduction end (8) and an outlet end (9) for the pencil (S), and the blade holder (5) having a bearing surface (15) which is positioned obliquely in relation to the axis (11) of the pencil-guiding channel (7), projects axially beyond the outlet end (9) of the guide sleeve (4) and is intended for positioning the shaving blade (3).

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.
