Abstract: An iron golf club head is disclosed. The iron golf club head can include a hosel portion, a heel portion, a toe portion, a face portion, and a sole portion all forged from a single piece of steel. The iron golf club head can further include a slot cut in the forged club behind the face portion between the heel portion and the toe portion. The slot can have a sole opening and a cavity opening, and a plug can be located in the sole opening.

Abstract: An adjustable golf club is disclosed. The adjustable golf club can include a club head having a sole. The sole of the club head may have two or more tracks located thereon. Each track can be configured to receive at least one weight. The two or more tracks may be three tracks. The three tracks can comprise an elongated central track, a first short track disposed on a first side of the elongated central track, and a second short track disposed on the second side of the elongated central track.

Abstract: The invention is directed toward a trial golf club head and method for determining the optimal loft angle for any golf club, and in particular a hybrid-type golf club. The invention includes a trial golf club head having a face portion, a leading edge portion, a toe portion, a heel portion, a back portion having a trailing edge portion, and a sole portion. The sole portion contains a number of equally spaced graduated indicia, which are substantially parallel to one another and extend from the toe portion to the heel portion. The distance between the graduated indicia is approximately 3.75 centimeters (cm), which corresponds to an incremental loft angle of approximately 3 degrees. The sole portion has a radius of curvature of 71.67 mm, which extends from the leading edge of the face portion to the trailing edge of the back portion.
