ABSTRACT:
The specification discloses a completely outside sharpenable saw chain of the chisel type in which top plate portions are sharpened on their tops and in which side cutter portions are sharpened on their outer sides. The chain has allochiral cutter teeth each having a top plate portion sloping rearwardly and downwardly and joined along one side edge to a side slitter plate portion sloping rearwardly and inwardly, a bent over shank portion, a body portion and a depth gauge portion, the top plate portion, the side slitter plate portion and the shank portion being generally C-shaped. The top plate portion has at its top a sharpenable surface forming a top cutting edge which joins a corner chisel point from which extends downwardly and rearwardly a side slitting edge formed by a side plate sharpenable surface. The top plate portions are sharpened employing an attachment securable to the nose end of a saw bar around which the saw chain passes, the attachment carrying a flexible strip of abrasive material held against the saw chain top plate portions as a result of flexure of said strip. The attachment further includes a pair of side elements having abrasive surfaces spring biased against the side cutter portions.
