A surgical sagittal saw blade assembly formed that includes a static bar, an oscillating blade head and at least one drive rod that reciprocates to oscillate the blade head. The bar is formed from two plates. A boss is pouch formed to extend up from one of the plates. The boss serves as the static pivot point around which the blade head oscillates. When the plates are secured together to form the bar, the top of the boss is welded to the inner surface of the second plate.
