Abstract: Various exemplary implementations of the principles described herein provide a cover for a golf club. The golf club may include a head and a shaft, the head having a heel end and a toe end, and the shaft connected at the heel end. The cover may include a toe portion substantially shrouding the toe end of the club head and a heel portion substantially shrouding the heel end of the club head and a first length of the shaft. The cover may include a sleeve portion extending from the heel portion and substantially shrouding a second length of the shaft, the second length being greater than the first length. The sleeve portion may have an opening opposite the heel portion. The cover may include a first pull member on the heel portion.

Abstract: A method and apparatus for prescribing overall club length for iron-type golf clubs for an individual player wherein the method comprises measuring the erect height (PH) of a player to be fitted, providing the player with a fitting ball club (FBC) having a spherical ball with a hosel bore therein, one end of a golf club shaft in the hosel bore and a golf club grip on the other end of the shaft, having the player hold the fitting ball club in address position as if about to hit a golf ball therewith, measuring the wrist-to-floor distance (WFM) vertically from the player's higher wrist to the floor, locating in the first two columns of the FIG. 4 table data corresponding to the PH and WFM measurements, respectively, for the player, deriving an incremental length LCC from the third, length control club column of FIG. 4, and adding that incremental LCC length to 37½ inches, thereby giving a prescribed overall club length for that player.

Abstract: A muscle-back iron golf club head includes a blade-like upper mass, a muscle-like lower mass, a planar front surface, a top surface, a sole surface, a heel surface, a toe surface, and a rear surface having a first contour. A recess is in the rear surface, the recess having a first portion in the blade-like upper mass and a second portion in the muscle-like lower mass. An insert may be provided in the recess, and such insert may substantially fill the recess and may include a back surface having a second contour which is different from the first contour of the club head rear surface.

Abstract: A golf club head having a striking wall, a front surface, a sole portion extending rearwardly from the rear surface, the sole portion having a forward end, a rearward end, an upper surface and a lower surface. The intersection of the upper surface and the rear surface defines an interior sole line. The intersection of the upper surface and the rearward end defines a trailing edge exterior sole line.
