(57) Saw chain (20) having generally upright plate-formed cutter links (22,24,26,28) connected by horizontally disposed wire-formed connector links (32,34). The cutter links cut a kerf wider than the connector links to protect the connector links. Bores (40,42) in the cutter links are larger than the cross-section size of the connector links permitting a limited degree of vertical movement between the cutter and connector links.
