Abstract

An automatically sharpenable saw chain cutting link having primary and secondary depth gauge elements. The primary depth gauge element controls the penetration of the top plate cutting edge into a kerf and is positioned a greater distance forward of the center of the cutting link than the top plate cutting edge is rearward of the center of the cutting link as required for automatic sharpening. The secondary depth gauge element is positioned adjacent the side plate cutting edge in the front to back and lateral directions but below the top plate cutting edge to avoid interference of the automatic sharpening function.
