Abstract
A hand-held dual knife sharpener comprises a gripping portion and an adjacent sharpener portion embodying coarse and fine sharpening devices on opposite sides thereof. The sharpener portion has two blade-receiving slots extending inwardly from the opposite sides and a sharpening device is located near the bottom of each blade-receiving slot. Each sharpening device comprises a pair of elongated blade sharpening elements arranged in converging and overlapping relationship to each other so as to define a V-shaped groove. The sharpener is fabricated of a pair of molded plastic mating components which are secured together and between which the four sharpening elements are entrapped.
