A machine is provided for removing the bark from logs. The machine supports a log for linear movement in the direction of the longitudinal axis of the log and for rotation about its longitudinal axis. A saw is supported for rotation about a second longitudinal axis generally parallel to the longitudinal axis of the log. The saw includes a saw blade wrapped around the second longitudinal axis in a helical pattern, the saw blade having a radially outer surface, a radially inner surface, and a cutting edge including saw teeth extending in the direction of the longitudinal axis of the log, the tips of the saw teeth projecting outwardly with respect to the saw blade. The saw is supported for selective engagement with the log, and is rotated about its longitudinal axis whereby the teeth will engage said log to strip the bark from the log.
