The accessory of claim 1, wherein the first arc-shaped opening is spaced from the first radial slot and the second radial slot, and the second-arc-shaped opening is spaced from the second radial slot and the third radial slot. 3. The accessory of claim 1, wherein the first radial slot is disposed at approximately 90 degrees to the axis, the second radial slot is disposed at approximately 180 degrees to the axis, and the third radial slot is disposed at approximately 270 degrees to the axis. 4. The accessory of claim 1, wherein the first arc-shaped opening subtends a first angle from approximately 120 degrees to the axis to approximately 150 degrees to the axis, and the second arc-shaped opening subtends a second angle from approximately 210 degrees to the axis to approximately 240 degrees to the axis. 5. The accessory of claim 1, wherein the second plurality of openings further comprises a third arc-shaped opening spaced radially outward from the central portion and extending in a circumferential direction between the first radial slot and the central opening, and a fourth arc-shaped opening spaced radially outward from the central portion and extending in a circumferential direction between the third radial slot and the central opening. 6. The accessory of claim 5, wherein the third arc-shaped opening is spaced from the first radial slot and the fourth arc-shaped opening is spaced from the third radial slot. 7. The accessory of claim 5, wherein the third arc-shaped opening is in communication with the central opening and the fourth arc-shaped opening is in communication with the central opening. 8. The accessory of claim 5, wherein the third arc-shaped opening starts at an angle of approximately 60 degrees relative to the axis, and a fourth arc-shaped opening starts at an angle of approximately 300 degrees relative to the axis. 9. The accessory of claim 1, wherein the rear end portion is configured to be coupled to a first attachment mechanism of a first type of oscillating power tool, the first attachment mechanism having first pair of clamping plates, a central post extending axially between the first pair of clamping plates, and a first plurality of projections extending axially from one of the first pair of clamping plates toward the other of the first pair of clamping plates and radially arranged about the post, such that the central opening receives the post without removal of one of the first pair of clamping plates from the post, and at least one of the first and second plurality of openings receive the first plurality of projections. 10. The accessory of claim 9, wherein the rear end portion is also configured to be alternately coupled to a second attachment mechanism of a second type of oscillating power tool, the second attachment mechanism having a second pair of clamping plates, one of which includes a second plurality of projections radially arranged around a center axis, such that at least one of the first and second plurality of openings receive the second plurality of projections. 11. The accessory of claim 1, wherein the central opening is generally U-shaped. 12. The accessory of claim 1, wherein the central opening comprises a pair of parallel side edges. 13. The accessory of claim 12, further comprising a notch defined in each of the pair of side edges. 14. The accessory of claim 1, wherein the rear end portion further comprises a rear edge defining a plurality of notches. 15. The accessory of claim 1, wherein the working end portion comprises at least one of a cutting edge, a saw blade, a sanding surface, and an abrading surface. 16. The accessory of claim 1, wherein the first arc-shaped opening subtends a first arc of approximately 30 degrees and the second arc-shaped opening subtends a second arc of approximately 30 degrees. 17. An accessory for coupling to an attachment mechanism of an oscillating power tool, the accessory comprising: a working end portion; andan opposite rear end portion configured to be coupled to a plurality of different configurations of attachment mechanisms for oscillating power tools, the rear end portion including: a central opening having a central portion configured to receive a central post of a tool clamping mechanism, and a rearward portion in communication with the central portion, extending rearward along an axis, and open to the rear end portion of the accessory;a first plurality of elongated openings in communication with and extending radially outward from the central portion of the central opening, the first plurality of openings including a first radial slot disposed at approximately 90 degrees to the axis, a second radial slot disposed at approximately 180 degrees to the axis, and a third radial slot disposed at approximately 270 degrees to the axis;a second plurality of openings including a first arc-shaped opening spaced radially outward from the central portion, subtending a first arc of a circle centered at a center of the central portion, and extending in a circumferential direction between the first and second radial slots, and a second arc-shaped opening spaced radially outward from the central portion, subtending a second arc of the circle centered at the center of the central portion, and extending in a circumferential direction between the second and third radial slots. 18.
