Claim 15:
16. A blade comprising:
an attachment portion configured to couple with an oscillating power tool and defining an anchor center about which the blade is configured to oscillate;
a first blade portion extending from the attachment portion and having a first cutting edge; and
a second blade portion extending from the first blade portion and having a second cutting edge,
wherein a longitudinal offset separates the first and second cutting edges in a longitudinal direction to configure the blade in a two-tiered arrangement configured to push cut,
wherein the first and second blade portions are generally coplanar, extend away from the attachment portion in a longitudinal direction, and are approximately symmetrical about a longitudinal axis,
wherein the second cutting edge is configured to be pushed a first distance to make a first linear cut in a workpiece without the first cutting edge engaging the workpiece, and wherein the first cutting edge is configured to be pushed a second distance greater than the first distance to extend the first linear cut colinearly,
wherein the longitudinal offset is at least 0.25 inches and configured to provide discontinuity between the two tiers of push-cutting.
