To provide an electric blade sharpener that efficiently grinds a cutter such as a kitchen knife, and can grind the kitchen knife or the like by moving the kitchen knife by one stroke, namely once in one way, without facing a blade to a grinding wheel more than once by grinding the blade from both surfaces when the kitchen knife or the like is moved and ground.
In the electric blade sharpener, a disk-like grinding wheel is mounted to rotary shafts turned by power of a motor. Two rotary shafts exist separately, at least one grinding wheel is mounted on each one of the rotary shaft, the grinding surface of each grinding wheel is a peripheral surface of the grinding wheel, the grinding wheel of one rotary shaft and the grinding wheel on the other rotary shaft are positionally shifted in the axial direction of the rotary shafts, and the blade is ground by moving the blade in the axial direction of the rotary shafts while applying the cutting edge to the grinding surfaces of the each grinding wheel.
