Abstract: An improved golf ball including a novel cover composition, including a blend of a high stiffness ionomer having a melt index of 0.5-5.0 g/min., flexural modulus of 60,000-120,000 psi and shore hardness of 70 or greater and a very low modulus methacrylic acid ionomer having a melt index of 0.5 to 10.0 g/min., flexural modulus of 2,000-8,000 psi or less and Shore D hardness of 20-50. The resulting golf ball shows improved resilience and playability over known golf balls.

Abstract: A composition useful to produce a golf ball cover of a blend of ethylene-methyl acrylate and an ionomer resin and a compatabilizer. The composition produces a cover material having hardness and feel comparable to Balata, but having improved resilience, durability and cut resistance over Balata.

Abstract: A set of golf clubs which utilizes progressively longer hosel lengths for the purpose of enlarging the main body of the clubhead and/or redistributing weight within the main body of the clubhead. The hosel length progresses from a very short hosel (13/8") on the lowest lofted iron, (the number 1 iron), to a conventional length hosel (25/8") on the sand wedge. By reducing the length of the hosel, weight is made available that can be used to enlarge the size of the clubhead and/or redistribute weight within the main body of the clubhead.

Abstract: The present invention is a composition for making a solid one-piece golf ball and the core of a two-piece or multi-layer golf ball with a butadiene base crosslinked by a methacrylic acid zinc salt. The resulting product is a golf ball with outstanding performance which possesses both resilience and durability and which can be reproduced accurately and economically. This type of golf ball is suitable for play by tournament caliber golfers.

Abstract: An iron type golf club head comprising a heel portion, a toe portion, a bottom sole portion, a top ridge portion, a hosel portion, a face surface having a center of percussion, a rear surface, a peripheral mass formed on the rear surface adjacent the heel, toe and bottom sole portions, the peripheral mass being further formed on a portion of the top ridge portion, with substantially the remainder of the top ridge portion being devoid of the peripheral mass, and a weight portion extending from the rear surface and disposed behind the center of percussion.
