摘要： A saw chain formed in part from planar cutting link blanks including a cutter portion having a top edge surface and a side surface that intersect to form a line edge. A leading portion of the curring link blank is twisted out of the plane of the blank so that the line edge becomes the cutting edge of the cutter and extends from the plane of the body to encompass the width of one side of the saw chain. Alternating cutting link are formed to have oppositely extended cutting edges to encompass the width of the saw chain. The cutting links preferably form certain of the center links of an assembled saw chain.
