<p>An anti-kickback saw chain including a series of left and right cutter links disposed alternatively on opposite sides of the chain. A novel safety link disposed in front of each cutter link functions to prevent a cutter portion in the cutter link, when rounding the nose of a saw bar, from cutting deeply into the wood. The safety link includes a leading projection adjacent the forward end of the link and a trailing projection adjacent the rear end of the link, the leading and trailing projections being separated by a gullet intermediate the projections.</p> |
