The invention is a cutter bar for a chain saw which permits quick and convenient trimming of hedges and shrubbery. The cutter bar is of conventional design, being relatively thin and elongated, and supporting a cutting chain which extends around its periphery. Additionally, the cutter bar of this invention has a plurality of spaced-apart tines which extend transversely out from the top and/or bottom of the cutter blade. The tines are fastened to or extend from a side or edge of the cutter blade, optionally by rivets passing through a shim or spacer-the tines are not connected to each other by a web or common casting other than the cutter blade. This way, the web or common casting does not add to the size, bulk, or weight of the cutter blade, allowing it to remain less burdensome and less interfering during cutting. In a preferred embodiment, the spacing on the cutter bar between tines varies so that branches or limbs of varying diameter may be accommodated by the cutter blade while cutting.
