    摘要: The present invention is for an improved pencil sharpener that is slidingly disposed about a pencil. The pencil sharpener comprises a cutting surface, a first arm pivotally mounted or connected with respect to a second arm, and a pencil receiving variable-sized aperture formed through the interior of the first arm and the second arm. The variable-sized aperture preferably alters in size and/or shape depending on the pivotal position of the first arm with respect to the second arm. The pencil receiving variable-sized aperture preferably forms a substantially conical channel when the first arm and the second arm are compressed inwardly for sharpening the pencil. In another position of the arms, the variable sized aperture permits the pencil to slide through the pencil sharpener. A resilient means such as a grommet and/or spring-loaded surfaces on the arm is resiliently provided within the pencil sharpener for automatically mounting the pencil sharpener to the pencil such that the pencil supports and carries the pencil sharpener. The pencil sharpener is therefore available to sharpen the pencil whenever needed.

    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.
