Multi-edge oscillating saw blade

A multi-edge saw blade for use in an oscillating tool, comprising:

• a proximal end that includes an attachment socket configured to mate with an oscillating drive member of a power tool and oscillate about an axis of oscillation;
• a distal end having a distal edge formed into a first cutting edge that includes a first row of cutting teeth situated across the distal edge and at least one row of perforations a spaced distance behind the first row of cutting teeth, wherein each of the at least one row of perforations realizes at least one breakaway line and at least one additional cutting edge comprising at least one additional row of cutting teeth;
• and
• wherein:
• each of the at least one row of perforations is sized and shaped such that responsive to a force applied orthogonally to a plane of the distal end of the multi-edge saw blade, a portion of the distal end between the first row of cutting teeth and the row of perforations nearest the distal edge breaks away from the multi-edge saw blade revealing an additional cutting edge;
• and
• each of the perforations defines one or more connection elements disposed between each blade, each of the one or more connection elements structured to break at a most narrow portion of the connection element.
