Abstract
A pencil sharpener (1) with a handle (3) and a sharpener insert (4) inserted into the handle (3) with a pencil guide channel (33) and a paring blade (34) is proposed, in conjunction with which the handle (3) is formed so as to correspond at least partially to the inner contours of a curved human hand (26). Improved ease of handling is achieved through the formed handle (3). Also proposed is a method for the manufacture of a pencil sharpener (1) of this kind, in which the handle (3) is formed in subsidiary areas so as to correspond to the inner contours of the human hand (26).
