There is described herein a sharpener for a carpenter's pencil having a centering collar (14) mounted to a base enclosure (12) for relative rotation to generate the sharpening effect. Within the base enclosure (12) there is a symmetrical pencil point contour surface (22) and a blade (26;40) mounted along the contour surface (22) for cutting against the inserted pencil. The shape of the blade (26;40) is either curved or formed from a plurality of sections (42,44) to produce a narrow cut around the point extremity of the pencil and a wider cut further up the pencil shaft.
L'invention concerne un taille-crayon pour crayons de menuisier comportant un collier de centrage (14) monté sur un boîtier de base (12), afin que leur rotation relative produise l'effet aiguisant recherché. Une surface (22) symétrique au contour en forme de pointe de crayon et une lame (26, 40), montée le long de ladite surface, sont montées au sein du boîtier de base (12) afin de tailler le crayon inséré. La forme de la lame (26, 40) est soit recourbée soit composée de plusieurs parties (42, 44), de manière à produire une coupe étroite autour de l'extrémité de la pointe du crayon et une coupe plus large plus haut le long du crayon.
