A cutting saw blade for use with an oscillatory power tool used in surgical bone cutting procedures including a blade having a distal end provided with teeth whose tips are oriented in a substantially linear row so that the terminus of all teeth lie in a solitary plane. Other tooth profiles assist in the cutting phenomena. The cutting blade has several spaced-apart pairs of notches disposed in the blade edges. Each pair of notches is adapted to cooperate with a pair of pins disposed on the oscillatory power tool to firmly retain the cutting blade to the saw. By providing the cutting blade with several sets of notches, the cutting blade is adjustable, in that it can be retained within the oscillatory power tool at different lengths. It has been found that such an adjustable cutting blade, having teeth oriented in a solitary plane, does not lose efficiency as the length of the blade is changed.
