A saw blade provided with two walls set apart from each other and with blade teeth arranged on each wall in a pattern along the distal end of each wall and on the inner surface of each wall. During a single cutting motion, the distal teeth provide the initial cut and the inner teeth remove additional material along the pathway. This increases the amount of material removed in one cut, leaving a small amount of material (bone) at the bottom of the slot for the surgeon to remove in the final step. Thus, the blade configuration and the tooth pattern of the saw blade improves the cutting efficiency.
