发明名称 Soft lead sharpener with pivotable profile knife
摘要 A sharpener for pencils with a soft lead with a sharpener housing has a conical sharpener channel, a sharpening knife which is fastened at the fastener housing and which is set tangentially to the sharpener channel. A shape-cutting knife, which can be swiveled into the sharpener channel, is provided with a manually actuated lever and with an arc-shaped, curved cutting edge for the selective shaping of the front end section of the lead. The sharpener is constructed as a double sharpener with individual sharpeners for pencils of different diameters placed opposite to one another in a common housing and the shape-cutting knives can be swiveled alternatively upward against the lead in the respective individual sharpener about a common axis, which is disposed at the common front end of the sharpener channels which are open in the upward and downward directions in this region.
