ABSTRACT:
A knife sharpening cutting board is disclosed in which a cutting board is provided with a recess along a peripheral edge and with intersecting pairs of knife sharpening disks mounted within the recess and rotatably secured to the cutting board for selective rotation about axes that are substantially parallel to one another and to the surface of the cutting board. The disks overlap one another radially to form an intersection that is adjacent to the top cutting surface of the board, and aligned with a groove formed in the board. The groove extends from the sharpening disks across the board to receive a knife blade as the knife is drawn across the sharpening disks. The recess is provided to receive the disks and to locate the disks within the board for protection and appearance purposes. Screws mounting the disks within the recess are accessible to facilitate disk removal.
