PURPOSE: To straighten the end of the toothed portion of each band saw blade and significantly enhance economicity and production efficiency at goode yields by manufacturing a plurality of band saws by means of pressing of the middle portion of a material in the longitudinal direction, the band saws each having the toothed portion at its middle portion.

CONSTITUTION: The middle portion of band steel 1 is pressed longitudinally at the middle of its width by pressing into a metal mold. The diagonals 4 in Figure represent portions punched by pressing. Thereby two band saws 5, 6 having toothed portions 2, 3 at their middle portions are manufactured. In such a manufacturing method, the middle portion of the band steel 1 which is not distorted is pressed and the edge portion of the band steel 1 which is distorted is not pressed so curving of the end of each toothed portion 2, 3 is prevented. Also, the band saws can be manufactured only by pressing and extra work as for further cutting the material is not required.
