US Patent 7387562 Blade sharpening device

A blade sharpening device is provided for honing a cutting edge of a blade. The device includes a block with a top honing surface, and a jig assembly mounted on the block. The jig assembly holds a blade in a fixed position adjacent the honing surface, and directed towards the honing surface, so that a sharpening stone can be manually moved on the top honing surface and across the blade edge for sharpening. The stone can be moved longitudinally, laterally, and circularly. The jig assembly is pivotally mounted on the block for a desired sharpening angle, and vertically adjustable so that the blade edge is substantially flush with the top honing surface of the block.
