Blender blade formed of titanium or titanium alloy

A method for forming a blender that is configured to slice foodstuff placed in the blender, the method comprising:

• providing a blender blade, wherein the blender blade comprises:
• a central body portion having a first upper surface, a first lower surface, and an aperture, wherein the central body portion is formed entirely of titanium or a titanium alloy;
• and
• a blade wing that extends from the central body portion in a direction, wherein the blade wing is formed entirely of titanium or the titanium alloy and the blade wing has a second upper surface, a second lower surface, and a first thickness therebetween, wherein the blade wing is nitrided subsequent to being formed, thereby covering the second upper surface of the blade wing with a layer of titanium nitride, thereby forming a nitrided surface of the blade wing such that the blade wing has a second thickness between the nitrided surface and the second lower surface that is greater than the first thickness and such that the nitrided surface is coplanar with the first upper surface, thereby forming a common upper surface of the central body portion and the blade wing;
• providing a rotatable shaft that has a threaded end;
• and
• coupling, with a fastener, the aperture of the central body portion of the blender blade to the threaded end of the rotatable shaft, wherein when the rotatable shaft rotates about an axis, the blender blade is configured to slice the foodstuff placed in the blender due to the aperture of the central body portion of the blender blade being coupled to the threaded of the rotatable shaft.

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.
