ABSTRACT:
A sharpener for sharpening an end of a writing stick by inserting the writing stick into the sharpener in a retentive or friction locking manner and rotating the sharpener and writing stick relative to each other, the sharpening of the writing stick generating waste material. The sharpener includes a sharpener body having an insertion end with an opening for receiving the end of the writing stick and a longitudinal axis extending through the opening. A sharpening blade is mounted on the body with its cutting edge arranged at an acute angle with respect to the longitudinal axis of the body. A chip collecting cap has an interior wall and is mounted on the body for enclosing an end of the body remote from the insertion end. A mechanism is provided for selectively securing and releasing the chip collecting cap with respect to rotation about the longitudinal axis of the body and a scraper is disposed at the body adjacent the interior wall of the chip collecting cap for scraping the waste material from the interior wall when the chip collecting cap is rotated relative to the sharpening body.
