<p>PURPOSE: To obtain the best size and weight distribution in main bodies of the heads of golf clubs whereby a golf ball can be driven more simply. CONSTITUTION: Provided is a set of golf clubs with hosel 12 becoming longer successively for making the main body of club head bigger or for redistributing the weight of the main body of club head. Specifically, the hosel becomes longer gradually from that (13/8 inch, about 3.50cm) of the iron (No.1 iron) of the smallest loft up to a conventional length (25/8 inch, about 67cm) in a sand wedge. In respect to the extra weight, the center of gravity of a club head is in the best position due to the redistribution around the periphery of cavity 24.</p> |
