a third lock point joined to and extending radially outwardly from the side wall and spaced apart from the first lock point by a second arcuate segment of the side wall, and the second arcuate segment has an arc length greater than an arc length of the first lock point.
13. The oscillating saw blade of claim 1 , and further comprising:
a third lock point joined to and extending radially outwardly from the side wall and spaced apart from the second lock point by a second arcuate segment of the side wall, and the second arcuate segment has an arc length greater than an arc length of the second lock point.
14. The oscillating saw blade of claim 1 , wherein the cap wall defines a plurality of arbor engagement apertures.
15. An oscillating power tool comprising:
a power tool connection clamp defining a clamp recess; and
an oscillating saw blade having:
an anchor disposed at least partially in a first plane and including:
a working portion;
a tool arbor engagement portion joined to the working portion, and the tool arbor engagement portion includes:
a side wall extending away from the first plane at essentially 90°, and the side wall includes an arcuate segment;
a cap wall joined to the side wall and disposed at least partially in a second plane, and the side wall and the cap wall at least partially define an arbor opening;
a first lock point joined to and extending radially outwardly from the side wall; and
a second lock point joined to and extending radially outwardly from the side wall and spaced apart from the first lock point by an arcuate segment of the side wall, and the arcuate segment has an arc length greater than an arc length of the first lock point.
