ABSTRACT:
This invention is a blade guide to allow the angle that the blade addresses a sharpening rod to be repeatedly and accurately re-established. This is accomplished through the provision of a guide plate outwardly projecting from the sharpening rod with a guide arm thereon. When the blade is placed with the back of the blade at the juncture between the guide plate and the guide arm, and the cutting edge of the blade against the sharpening rod the angle the blade addresses the sharpener can repeatedly be re-established before each sharpening stroke of such blade against the sharpener. Once this correct angle is established, it can be maintained even through the blade is no longer engaged with the guide. By making the guide arms adjustable longitudinally along the guide plate, the optimum angle can be set for an infinite number of different sizes of blades. Also indicia is provided on the guide plate so that the proper location of the guide arm can be readily determined by reference to such indicia.
