The high-speed blending blade of claim 1, wherein each of the upwardly arcuate blades, downwardly arcuate blades, central blade portion and top blades have a thickness of approximately 3 millimeters. 3. The high-speed blending blade of claim 1, wherein each of the top blades includes a leading edge and a trailing edge with an inward surface extending therebetween, wherein the leading and trailing edges are substantially perpendicular to the inward surface. 4. The high-speed blending blade of claim 1, wherein the top blades extend upward from proximate the central blade portion at an angle of approximately 72 degrees relative to the central top surface. 5. The high-speed blending blade of claim 1, wherein the downwardly arcuate blades are substantially perpendicular to the upwardly arcuate blades, and wherein the top blades are substantially parallel with the downwardly arcuate blades. 6. A high-speed blade for a food-processing appliance, the high-speed blade comprising: a downward blade portion including first and second blades, wherein each of the first and second blades define a continuous downwardly curved top surface;an upward blade portion including third and fourth blades, wherein the third and fourth blades define a continuous upwardly curved top surface; anda central blade portion that receives the upward and downward blade portions, wherein each continuous downwardly curved top surface and continuous upwardly curved top surface includes a transition portion that engages and is substantially co-planar with a central top surface of the central blade portion, the central blade portion having a connecting aperture. 7. The high-speed blade of claim 6, further comprising top blades extending at a predetermined angle from an area proximate the central blade portion. 8. The high-speed blade of claim 7, wherein the top blades extend upward from proximate the central blade portion at an angle of approximately 72 degrees relative to the central top surface. 9. The high-speed blade of claim 7, wherein the top blades are connected by a central region that engages the central blade portion to substantially fix a position of the top blades relative to the upward and downward blade portions. 10. The high-speed blade of claim 7, wherein the top blades include two opposing top blades. 11. The high-speed blade of claim 10, wherein the two opposing top blades are substantially aligned with a first longitudinal axis extending through the downward blade portion. 12. The high-speed blade of claim 6, wherein the first and second blades define opposing downwardly curved blades, and wherein the third and fourth blades define opposing upwardly curved blades. 13. The high-speed blade of claim 7, wherein the upward, downward and central blade portions and the top blades are made of a material having a thickness of about 3 millimeters. 14. A high-speed blending blade for a food-processing appliance, the high-speed blending blade comprising: a continuously curved convex blade portion having a thickness of approximately 3 millimeters;a continuously curved concave blade portion having a thickness of approximately 3 millimeters; anda central blade portion that receives the continuously curved convex and concave blade portions, the central blade portion defining a fastening aperture. 15. The high-speed blending blade of claim 14, wherein the continuously curved convex blade portion includes opposing first and second blades that extend from the central blade portion along a first longitudinal axis, wherein each of the first and second blades defines a downward curve along the first longitudinal axis, each downward curve having a first radial length, and wherein the continuously curved concave blade portion includes opposing third and fourth blades that extend from the central blade portion along a second longitudinal axis, wherein each of the third and fourth blades defines an upward curve along the second longitudinal axis, each upward curve having a second radial length, and wherein the first and second radial lengths are substantially similar. 16. The high-speed blending blade of claim 14, further comprising: top blades extending at a predetermined angle from an area proximate the central blade portion, wherein the top blades are made of a material having a thickness of 3 millimeters. 17. The high-speed blending blade of claim 14, wherein the continuously curved convex, continuously curved concave and central blade portions define top and bottom surfaces, wherein each of the top and bottom surfaces at least partially defines a substantially hyperbolic surface. 18. The high-speed blending blade of claim 15, wherein each of the first, second, third and fourth blades includes leading and trailing edges, wherein the leading edge is disposed at an angle of between approximately 43 degrees and approximately 47 degrees relative to a top surface of the central blade portion, and wherein the trailing edge is substantially perpendicular to the top surface of the central blade portion. 19. The high-speed blending blade of claim 16, wherein each of the top blades includes an inward surface that extends between an upper leading edge and an upper trailing edge, wherein the upper leading edge is disposed at a predetermined edge angle relative to the inward surface and the upper trailing edge is substantially perpendicular to the inward surface. 20.
