The chain saw includes a bar, terminating in a nose with a curved profile and the upper quadrant of the nose curves about a centre of curvature located inwardly from the end of the nose and between top and bottom margins of the bar. A saw chain is mounted on the bar guided for movement along top and bottom margins of the bar and over the nose. The saw chain has left and right-hand cutter links distributed along the length forming side links in the chain. The chain has other links completing the chain, including an opposing side link opposite each cutter link and forward and rear centre links. |
