A cutting device includes a generally planar guide bar having a peripheral groove. An endless saw chain is disposed around the guide bar and includes links and connector elements joining the links to each other to form an endless chain loop. The links include drive links and consecutive tooth links connected to a same one of the drive links. Each tooth link includes a cutting tooth protruding from one side of the saw chain. Consecutive cutting teeth of the tooth links are arranged to alternate to right and left sides relative to a plane defined by the guide bar. The saw chain is operably circulated around the guide bar groove for cutting.
