发明名称 Forward-positionable eraser for a writing implement and method
摘要 A writing implement having a forward-positioned eraser, and method. The eraser circumscribes the shaft of the writing implement, and may have an annular or doughnut shape. The eraser may be affixed to the shaft portion, for example where used with a fixed-length writing implement such as a mechanical pencil or erasable pen. The eraser may, alternatively, be slidable along the shaft portion, which would make the eraser useable with a sharpenable pencil, the length of which will be changed as a result of sharpening.
