CES-16
The first slot 142 includes a first scalloped edge 146 at one end and an opposite end that connects to and is in communication with the aperture 120. The second slot 144 includes a second scalloped edge 148 at one end and an opposite end that connects to and is in communication with the aperture 120. In one embodiment, the first scalloped edge 146 and second scalloped edge 148 are concave structures at the end of the first slot 142 and second slot 144 respectively. The first scalloped edge 146 and second scalloped edge 148 can facilitate evacuation of debris while the surgical saw blade 100 is cutting. In particular, the first scalloped edge 146 and second scalloped edge 148 can facilitate evacuation of debris from the back side 204 through the aperture toward the front side 202.

CES-16
The bevels 134 cooperate to provide a sharped edge for the cutting edge 132 to facilitate cutting of the tissue. Those of skill in the art will recognize that the bevels 134a-e may have uniform angles, shapes, and sizes. Alternatively, or in addition, the bevels 134a-e may each have a variety of different combinations of angles, shapes, and sizes.

CES-16
The second side 140 extends between the base 136 and the cutting edge 132 on a side opposite the first side 138. The second side 140 defines a second slot 144 between the second side 140 and the surgical saw blade 100. The second side 140 includes a second side bevel 134b that extends between the second side 140 and a surface of the cutting tooth 130. In certain embodiments, the first side bevel 134a and second side bevel 134b slope at the same angle and are the same size/shape. In another embodiment, the first side bevel 134a and second side bevel 134b slope at different angles and have different sizes/shapes. In one embodiment, the first side bevel 134a and second side bevel 134b are parallel to each other. In another embodiment, the first side bevel 134a and second side bevel 134b may be angled in relation to each other such that the side bevels 134 are closer to each other near the cutting edge 132.
