CA 2378548

A pencil sharpener including a self-governing sharpening assembly, a motor for driving the sharpening assembly, and a selector guide. The selector guide defines a plurality of openings positionable for aligning pencils of various sizes with the sharpening assembly. The sharpening assembly includes a rotary blade and a shaft having a reduced diameter portion. A blade holder defines a conical cavity for receiving a pencil and is driven by a drive shaft. A stop is connected to the lower end of the shaft and is slidably mounted to the blade holder in alignment with the conical cavity and is biased by a spring member to position the reduced diameter portion of the shaft away from the bearing lug of the blade holder. Sharpening ceases when a pencil moves the stop, causing receiving of the reduced diameter portion in a bearing lug and pivoting of the rotary blade away from the pencil.
