A pencil sharpener including housing, a rotary seat disposed in the housing, and a driver for rotationally driving the rotary seat. A blade unit includes two rotary blades that are disposed on the rotary seat and converge to define a sharpening angle. The sharpener also includes cooperating gears that rotate each blade about its associated longitudinal axis, and rotate the blades about a central axis therebetween. One of the rotary blades has a reduced diameter section, and the rotary seat has a projecting stop that corresponds to the reduced diameter section. The stop is positioned in a cavity of the rotary seat for the tip of a pencil to abut against so as to locate the pencil.
