PROBLEM TO BE SOLVED: To provide a saw in which both the long saw blade part of an under blade and the short saw blade part of the under blade are intermingled and discharge positions of wood waste respectively differ and also an interval between the tip of the blade edge of the under blade and the tip of the blade edge of an adjacent back blade on the front side in the sawing direction becomes long by such the rate that the under blade is made long and discharge of wood waste is well performed. SOLUTION: A plurality of pieces of chevronlike saw blade parts 2 are formed in the side edge of the body 1 of the saw. Blade faces consisting of three kinds of an under blade on this side in the sawing direction Q, a back blade on the rear side and the upper teeth in the tip part are alternately formed right and left on both sides of a saw blade part. Also, the saw blade part is alternately divided right and left to give set of saw teeth.
