Paragraph Number

88

While the saw blades 100, 200 are shown with rectilinear arrays of cutting teeth 130, 230, in other examples the teeth may be positioned in any array configuration. Some examples include arcuate, spiral, or other polynomial. In one example, the teeth may be arranged along arcuate paths that are all concentric with the center point of saw blade oscillation, optionally including the tooth offset discussed above.
