A saw blade and saw-blade support are provided for a power-driven saw. The saw blade has planar cutting members and planar link members which are pivotally connected together. Each cutting member has a recess for receiving a portion of a link member. The saw-blade support is a blade support face, including a generally straight first section for bearing the cutting load, an arcuate second section merging with the straight first section and defining an end of the elongate member, and an arcuate third section merging with the arcuate second section, but having less curvature than the second section. The end of the saw-blade support carried by the power drive components has an outwardly-flared guide wall for leading said saw blade from the power drive onto the saw-blade support.
