Abstract: A device is disclosed to make slits through the bark of a log with a chain saw. The chain saw has a blade with a chain which runs over its extreme free end which is preferably semicircular in shape. Rotatable guide rollers are mounted on both sides of the extreme end of the blade and are preferably coaxial with the semicircular end. The lateral surfaces of the guide rollers face each other and guide rollers in operation hold the chain of the chain saw in contact with a log to be cut for cutting slits of a given depth through its bark.
