A pair of companion saw blade tooth set dies are provided for guided relative movement toward and away from each other relative to a support structure from which a saw blade may be guidingly supported for predetermined indexed positioning of right and left set teeth thereon relative to the location of the aforementioned companion tooth set dies. The dies, when moved into engagement with the right and left set teeth of the saw blade, are operative to engage and bend the right and the left set teeth back to and past neutral set positions and to the reverse set positions with the previous right and left set teeth comprising left and right set teeth, respectively, and the bend areas of the reverse set teeth being formed in the longitudinal marginal portion of the blade from which the teeth project.
