Saw blade with reduced modal frequencies in the operating frequency range

A circular cutting blade comprising:

• a circular body including a periphery and a central aperture defining a center point;
• a plurality of teeth spaced around the periphery of the body;
• a set of fully enclosed, arcuate, inner body slots defined in the body, concentric with the center point, each inner body slot extending in a circumferential direction from a first distal end to a second distal, where all of the inner body slots are disposed a first radial distance from the center point, and each pair of adjacent inner body slots are spaced apart by an equal circumferential distance, the set of inner body slots including a first inner body slot disposed between a 12 o'clock position and a 3 o'clock position, a second inner body slot disposed between the 3 o'clock position and a 6 o'clock position, a third inner body slot disposed between the 6 o'clock position and a 9 o'clock position, and a fourth inner body slot disposed between the 9 o'clock position and a 12 o'clock position;
• and
• a set of fully enclosed, arcuate, outer body slots defined in the body, concentric with the center point, each outer body slot extending in a circumferential direction from a third distal end to a fourth distal, where all of the outer slots are disposed a second radial distance from the center point that is greater than the first radial distance, and each pair of adjacent outer slots are spaced apart by an equal circumferential distance, wherein each outer body slot is generally aligned radially with a corresponding one of the inner body slots, the set of outer body slots including a first outer body slot disposed between a 12 o'clock position and a 3 o'clock position, a second outer body slot disposed between the 3 o'clock position and a 6 o'clock position, a third outer body slot disposed between the 6 o'clock position and a 9 o'clock position, and a fourth outer body slot disposed between the 9 o'clock position and a 12 o'clock position.
