Abstract
A blade configured for use in a blending apparatus includes a body portion and a pair of wing portions extending from the body portion. At least a leading edge of the blade is forged to increase a hardness property. The leading edge may have a minimum thickness that provides a relatively blunt leading edge. The wing portions of the blade may be formed after forging the blade.
