ABSTRACT:
A disposable lead pencil, eraser and sharpener combination in which there is an eraser mounted upon one end of the housing and an abrasive sharpener structure contained within an enclosed and sealed chamber at the opposite end of the pencil housing. Sharpening of the lead is effected by reciprocating a pusher plate mounted upon the side of the housing back and forth to move the lead back and forth relative to the abrasive sharpener. At the end of each reciprocal stroke of the lead, an indexing mechanism automatically rotates the lead relative to the abrasive element so that a different section of lead is presented to the sharpener during each stroke. The sharpener containing chamber of the pencil housing is sealed so that all lead filings are retained within the pencil's housing.
