A carpenter's pencil sharpener (10) for cutting a point on a flat pencil (23) has a base enclosure (12) and a centering collar (14) rotatably mounted on the base enclosure (12) and cooperatively defining a longitudinal central axis (13). The base enclosure (12) has a pencil contour surface (22) generally matching a desired contour of the pencil (23). The collar (14) positions the pencil (23) generally along the central axis (13) during rotation of the collar (14). A flat blade (26) has a cutting edge (28) positioned along the contour surface (22) at an angle (a) of approximately 10-13 degrees relative to the central axis (13) for cutting against the pencil (23) when the pencil (23) is rotated about the central axis (13).
L'invention concerne un taille-crayon de menuisier qui permet de tailler la pointe d'un crayon plat. Ce taille-crayon possède un logement de base et un collier de centrage monté rotatif sur le logement de base, ces deux éléments définissant ensemble un axe central longitudinal. Le logement de base possède une surface de contour de crayon qui épouse généralement un contour désiré du crayon. Pendant sa rotation, le collier positionne le crayon généralement le long de l'axe central. Une lame plate possède un bord coupant positionné le long de la surface de contour à un angle d'environ 10-13 degrés par rapport à l'axe central de manière à tailler le crayon lorsque ce dernier est mis en rotation autour de l'axe central.
