ABSTRACT:
A guide bar has a groove extending along the top and bottom edges and continues in a semi-circular path around the outer end. A cutting chain has drive tangs that slide in said groove to guide the cutting chain along the edges of the bar. A thin rigid plate is fixed to one or both sides of the guide bar near the outer end thereof and extends slightly past the outer end to form a safety rail that reduces the degree of hooking that is caused by the depth gauges and cutters of the cutting chain digging into or hooking onto a tree or branch being cut.
