Abstract: A perimeter weighted iron-type golf club head with a recessed or cavity back and a peripheral mass having an improved weight configuration formed of weight members within the cavity which are positioned adjacent to and on opposite sides of the center of gravity of the golf club head and located between the center of gravity and the peripheral mass of the golf club head.

Abstract: A perimeter weighted iron-type golf club head with a recessed of cavity back and a peripheral mass having an improved weight configuration formed of angularly disposed weight members within the cavity which are positioned adjacent to and on opposite sides of the center of gravity of the golf club head and located between the center of gravity and the peripheral mass of the golf club head.

Abstract: A perimeter weighted iron type golf club head having a recess or cavity back and peripheral mass with an improved weight configuration formed of a raised concentrated mass weight member within the cavity and located at the center of percussion of the golf club head.

Abstract: A perimeter weighted iron type golf club head having an upper alignment and sighting area formed on a top ridge of the club head approximate the toe and positioned perpendicular to the intended line of flight and parallel to the longitudinal axis of the club face to aid the golfer in aligning the club head "square" or perpendicular to the intended line in the address position. The club head also includes a centrally located complementary weight within the cavity in the back of the club head in the form of a concentrated mass located at the center of percussion of the golf club head.

Abstract: An iron type golf club having an alignment and sighting area formed on the top ridge of the club head proximate the toe and positioned perpendicular to the intended line of flight and parallel to the longitudinal axis of the club face or the grooves on the ball striking face to aid a golfer in aligning the club head square to the intended target line in the address position.

Abstract: A wood-type golf club having a deep, channel-shaped cavity formed in the top surface of the club extending rearwardly from the ball striking face. The ball striking face has a height which is at least 50% of the distance between the top surface and the bottom surface of the club head. The depth of the cavity is at least 1/4 inch from the top surface of the club head the width of the cavity is at least 1/2 inch. The cavity preferably is further characterized as having an aspect ratio, defined as the square of the width at a transverse cross section of the cavity divided by the area of that transverse cross section, of less than 20. The cavity preferably has an average transverse gradient, defined as an angle between a line from the bottom low point of the cavity at a transverse cross section of the cavity to the cavity edge and a line across the top of the cavity at that cross section, greater than 3 degrees along the cavity's length.

Abstract: A perimeter weighted iron-type golf club head with a recessed or cavity back and a peripheral mass having an improved weight configuration formed of weight members within the cavity which are positioned adjacent to and on opposite sides of the center of percussion of the golf club head and located between the center of percussion and the peripheral mass of the golf club head.

Abstract: A rotatable golf club holder insert adapted to be inserted in a golf bag and a golf bag having such an insert preferably including a series of golf club dividers forming separated compartments to receive the golf clubs and coupling means associated with the golf bag for permitting the club holder insert to be rotated in a 360 degree manner in either direction so that the insert may be rotatably relocated to an optimum frontal position relative to a golfer so that the golfer can easily withdraw or replace a club from or in the bag.
