1. A method for making a wood-type golf club head, comprising:
- creating a face portion for the golf club head, wherein the step of creating the face portion comprises;
obtaining a blank from a piece of sheet metal consisting essentially of a titanium alloy,after obtaining the blank, exposing the blank to a pressure of about 70 tons psi, andheat treating the blank to increase the hardness of the blank; and
attaching the face portion to a crown and a sole of the golf club head after heat treating the blank, whereinthe piece of sheet metal from which the blank is obtained has a substantially uniform thickness.

Abstract
In one aspect, the invention provides a face for a golf club head. In one embodiment, the face includes an upper portion and a lower portion, wherein the lower portion has a lower toe portion located towards the toe of the golf club head, a lower heel portion located towards the heel of the golf club head, and a center portion extending from the lower toe portion to the lower heel portion, wherein the lower toe portion and the lower heel portion have a first substantially uniform thickness, the center portion and the upper portion have a second substantially uniform thickness, the second substantially uniform thickness is greater than the first substantially uniform thickness, the first substantially uniform thickness is in a range of about 0.055 inch to about 0.09 inch, and the second substantially uniform thickness is in a range of about 0.070 inch to about 0.13 inch.

16. A wood-type golf club head, said wood-type golf club head comprising a face having (1) an upper portion, (2) a lower portion, (3) a toe side edge, (4) a heel side edge, and (4) a bottom edge,
said lower portion having (a) a lower toe portion located towards a toe of the golf club head, (b) a lower heel portion located towards a heel of the golf club head, and a (c) center portion located between the lower toe portion and the lower heel portion, said lower toe portion and said lower heel portion each (a) being substantially oval in shape, (b) having a side that is generally parabolic in shape, and (c) having a first substantially uniform thickness, said center portion and said upper portion having a second substantially uniform thickness, said second thickness being thicker than said first thickness, wherein said parabolic side of the lower toe portion extends from a point substantially on the toe side edge of the face to a first point substantially on the bottom edge of the face; -
said parabolic side of the lower heel portion extends from a point substantially on the heel side edge of the face to a second point substantially on the bottom edge; and said center portion has (1) a heel side that coincides with the side of the lower heel portion that is generally parabolic in shape, (2) a toe side that coincides with the side of the lower toe portion that is generally parabolic in shape, and (3) an upper side that coincides with at least a portion of a lower side of the upper portion. - View Dependent Claims (17, 18, 19)
