Abstract
A pencil sharpener has a housing, a single cutter mounted for rotation in the housing, and a fixed pencil guide mounted in the housing and having an opening facing the cutter to expose the end of a pencil to the cutter. A rotatably mounted tube coaxial with the pencil guide extends through the housing and has a gear secured to its outer periphery within the housing. Means simultaneously rotate the cutter and gear. A sleeve mounted on the tube exterior of the housing carries a pair of opposed arms pivotally mounted each of which has a finger to engage a pencil, the tube having a slot to accommodate each finger. A spring interposed between the tube and the sleeve urges the sleeve and the arms in a direction to feed the pencil into the fixed pencil guide.
