Abstract
A pencil has a fixed non-replaceable eraser and a moveable sleeve. The fixed non-replaceable eraser is elongated to provide a larger eraser to pencil ratio in order to have more erase cycles per write cycles. The moveable sleeve can be moved to selectively expose a portion of the eraser. A ferrule couples the pencil body and the eraser together and provides an outer surface to engage an inner surface of the moveable sleeve. In one embodiment, a threaded female slot in the outer surface of the ferrule engages a male threaded tab in the inner surface of the sleeve. In another embodiment, a plurality of concentric slots in the outer surface of the ferrule engage a tab in the inner surface of the sleeve.
