1. A surgical saw blade for penetrating bone when said surgical saw blade is operatively coupled to an oscillatory power tool, comprising:

  • a surgical saw blade having a proximal end and a distal end;

    said proximal end having a hub for attachment to an oscillatory power tool for driving engagement thereby;

    said distal end having a plurality substantially identically shaped cutting teeth ending in a distal tip configured to be placed substantially on a tangent which is perpendicular to a radial line extending from the center line of the power tool cutting axis that bisects the arc of travel within which the blade travels such that said teeth contact the bone to be cut thereby to provide better tracking of said surgical saw blade when forming a kerf in the bone, whereupon said teeth cut both progressively and sequentially as the kerf begins to form to provide faster aggressive cutting and efficient chip removal; and

    a lubricious coating material having a Rockwell hardness of about 65 to about 90 being applied to the outer surface of the surgical saw blade.
