Abstract

Abstract A base panel for wall mounting has on its outer face a transverse outwardly projecting housing of greater depth than the blade width of the knives to be accommodated. The projecting housing is provided with a slot or slots to receive knife blades therethrough. Each slot has associated with it internally of the housing a pair of sharpening elements adapted to engage the blade edge on opposite sides and a resilient means for biasing the blade edge toward and in sharpening contact with the sharpening elements and for holding the blade or blades in the slots during periods of storage. Each placement and withdrawal of a blade results in a sharpening action on the blade. The device includes a protective cover for the blades when in the storage position.
