Abstract: A pencil sharpener for non-circular section pencils comprising a first tubular element for receiving the pencil without permitting the sliding or rotation of the latter relatively to the former. The sharpener is fitted with cams near the top end thereof, a second tubular element with a reduced tubular extension at one end thereof forms a stop for the first element, with a communicating hole between the second element and the extension shaped as a cam, carrying the cutting blade of the sharpener. The second element has at the other end a closing disk fitted with an abutment on the inner side and a cam-like profile hole similar to the communication hole between the second element and the extension. The holes are designed to receive a third pair of cams at the end of the first element.
