Claim 18:
19. A blender that comprises:
a rotatable shaft that includes a threaded end;
a blender blade that is configured to slice foodstuff placed into the blender as the rotatable shaft rotates about an axis, wherein the blender blade comprises:
a central body portion that is coupled to the threaded end of the rotatable shaft via an aperture of the central body portion and a fastener, wherein the central body portion is formed entirely of titanium or a titanium alloy and the central body portion includes a first upper surface and a first lower surface;
a first blade wing that extends from the central body portion in a first direction, wherein the first blade wing is formed entirely of titanium or the titanium alloy and the first blade wing has a second upper surface, a second lower surface, and a first thickness therebetween; and
a second blade wing that extends from the central body portion in a second direction, wherein the second blade wing is formed entirely of titanium or the titanium alloy and the second blade wing has a third upper surface, a third lower surface, and a second thickness therebetween,
wherein the second upper surface of the first blade wing and the third upper surface of the second blade wing-are nitrided subsequent to the first blade wing and the second blade wing being formed, thereby covering the second upper surface and the third upper surface with a layer of titanium nitride, thereby forming a first nitrided surface of the first blade wing and a second nitrided surface of the second blade wing such that the first blade wing has a third thickness between the first nitrided surface and the second lower surface that is greater than the first thickness and such that the first nitrided surface is coplanar with the first upper surface, thereby forming a common upper surface of the central body portion and the first blade wing.
