Blender blade assembly

A blender blade assembly comprising:

• a blender blade comprising:
• a central body having an axis of rotation;
• a plurality of blending arms equidistantly spaced and radially extending from the central body, wherein each blending arm comprises a base adjoining the central body, an end distal from the central body, a middle section between the base and the end, a front cutting edge, a back edge opposite the front cutting edge, and a thickness within the range of 0.2 to 2.5 millimeters;
• wherein at least one first blending arm is planar to the central body, at least one second blending arm includes a bend in the middle section at an angle relative to the central body in the range of about 2° to 9° in a first direction, and each of at least two third blending arms include a bend in the respective middle sections at an angle relative to the central body in the range of about 10° to 22° in a direction opposite the first direction;
• a shaft coupled to the blender blade at a first end and configured to couple with a blender motor at a second end opposite the first end;
• a housing encasing a substantial portion of the shaft;
• a seal contacting the shaft at two points including an entry point to the housing to prevent any blended food material from entering the assembly housing, wherein a first contact point of the seal is comprised of polytetrafluoroethylene (PTFE) and a second contact point of the seal is comprised of a fluorocarbon elastomer material.
