ABSTRACT:
A flexible saw blade particularly well suited to the cutting of tree limbs, having a predetermined rivet pressure which assures that just the right degree of rivet pressure will act on transversely adjacent cutting links so that pivoting is easy but not too loose; having teeth pointed in predetermined directions to ensure sufficient kerf width to allow the flexible saw blade to pass through the limb as it cuts and prevents uncut wood from forming a ridge between the rows of cutting links, which would otherwise have the effect of impeding the cutting operation; and having a turn-link optionally incorporated which causes the flexible saw blade to automatically right itself with respect to the limb surface upon being passed over the limb and before actual cutting begins.
