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.
