Patent ID: 11351655

Abstract:
An acute angle blade sharpening apparatus and method for sharpening blades is configured to sharpen the edge and bevel of a blade at the specific acute angles between 21° and 23°, or about 22° and 23°. The apparatus has a base member forming multiple elongated depressions oriented at 22° and 23°. Multiple elongated sharpening members are fixedly mounted in the depressions. The blade is oriented perpendicular to the first side of the base member and drawn against the sharpening members, to engage at the desired 22° and 23° sharpening angles. A leveling instrument attaches to the blade to verify the blade is oriented at the desired angles. A leveling instrument cavity stores the leveling instrument and fastener. Springs retain the sharpening members in the cavity of the base member when not in use. A clamp fastens the base member to a mounting surface for enhanced stability.
