Abstract: The present invention relates to a knife sharpening device. In particular, when a blade unit of a scissor knife or a kitchen knife is polished against a rotating polishing whetstone, the blade unit of the scissor knife or the kitchen knife comes in contact with the polishing whetstone while being easily moved in left and right directions along the surface of the blade unit. To this end, a cover is disposed on the outside of the polishing whetstone which is rotated at a high speed by a motor. In addition, a fastener and a rotating fastening member connected to the outside are connected to one side of the cover, before a rotating rod is connected to one side and a reciprocating rod is connected to the other side by a connecting pin. At the other side of the reciprocating rod, a fixator having a fixating groove for fixating the blade unit of a scissor or a knife is disposed. Therefore, the angle of the blade unit is adjusted by the fixator and the rotating fastening member such that the blade unit may come in contact with the surface of the polishing whetstone. Furthermore, the rotating rod and the reciprocating rod intersect with each other while allowing the blade unit to be moved in right and left directions in a contacted state. Consequently, even a novice worker can allow the blade unit of a scissor or a knife to touch the polishing whetstone which is rotated at a high speed in order to fixate the front surface of the blade unit formed in a longitudinal direction to the fixator, such that the entirety of the blade unit may come in complete contact with the surface of the polishing whetstone. Accordingly, the present invention provides an advantage of preventing a safety accident because the worker does not have to directly grasp the blade unit, an advantage of improving polishing quality of the blade unit by enabling uniform polishing with the identical power while being moved in right and left sides, and an advantage of allowing a novice to simply and easily perform polishing of the blade unit.
