The Model 76's serrated edge can be maintained with standard sharpening tools, though the heat-treated alloy steel blade holds its edge through hundreds of digs before requiring maintenance. When sharpening serrated teeth, work each tooth individually with a small round file that matches the tooth's curve, maintaining the original bevel angle. The smooth cutting edge on the opposite side of the blade can be sharpened with a standard flat file or sharpening stone. Detectorists who use this digger in rocky soil or root-heavy ground sharpen the blade once per season to maintain cutting performance.
