A surgical saw blade operatively couples to an oscillatory power tool for oscillation about an oscillation axis (OA). The saw blade includes a plurality of cutting teeth separated from one another by a clean out opening along a distal end. The clean out opening comprises an arcuate closed end and straight side walls extending from the closed end. Each tooth comprises first and second rake surfaces and first and second relief surfaces intersecting to define first and second cutting edges, respectively. The first and second cutting edges are oppositely disposed from one another. One cutting tooth protrudes a distance (de) from one side face of the blade and the next adjacent cutting tooth protrudes the same distance (de) from the other side face of the blade to cut a groove having a width (dg) wider than the thickness (t) of the blade.
