Sliding sharpening device for pencil with non-circular cross section

摘要

A sharpener for a carpenter's pencil that creates a profile shape desired by carpenters rather than a conical point. One end of the sharpener creates a sharpened profile on the narrow side of the pencil, while the opposite end of the sharpener creates a sharpened profile on the wide side when the pencil is rotated 90° about its axis. The pencil is slid laterally back and forth in a guide member, advancing along its axis as material is removed from the narrow side by fixed blades shaving material at an angle. The pencil is then rotated 90° and inserted in the other guide and moved back and forth advancing along its axis as material is removed from the wide side by fixed blades in a similar manner.
