A knife sharpening device includes a base with a motor and a gear reduction assembly connected thereto. A main shaft is connected to the gear reduction assembly and two grinding disks are mounted on the main shaft. A separation tube is mounted on the main shaft and located between the two grinding disks. Each grinding disk has a spring urging thereto so as to prevent the grinding disks from shaking. A cover is mounted to the base and has straight slots each of which is in communication between two openings. Each slot includes two narrow ends which communicate with the two openings so that the blades of knives are inserted perpendicularly in the slots and the cutting edge is slightly clamped by the narrow ends.
