In general, golf is a kind of sport in which a ball is hit in one of the holes, in the order of drive, approach and putting, and put in a hole cup located on the opposite side.

In order to play golf, a tool for hitting and blowing a ball is needed. This tool is a golf club. The golf club is a wood club for driving a driver for a long distance hit, and a medium distance and an approach An iron club, and a putter that puts the green ball into the hole cup.

The golf club is divided into a grip, a shaft and a head. An angle that determines the distance of a hit portion on one side of the head is referred to as a loft angle. The loft angle indicates a distance As the loft angle is smaller with respect to 0 °, the flying distance becomes longer and the flying distance of the ball becomes shorter as the loft angle is larger.

Such golf clubs are required to have a number of clubs ranging from 1 wood club to 9 iron clubs and putters depending on the loft angle and shaft length.

The loft angle of a conventional golf club according to the invention is described as Iron 2: 19 degrees, 3 times: 22 degrees, 4 times: 25 degrees, 5 times: 28 degrees, 6 times : 32 degrees, 7 times: 36 degrees, 8 times: 40 degrees, 9 times: 44 degrees

Pitching wedge (Pw) = 48 degrees

Approx wedge (W) = 52 degrees,

Sand Wedge = 56 degrees,

Lob Wedge = 60 degrees,

1 Wood (Wood): 5 to 13 degrees,

3 wood (Wood): 13 degrees to 15 degrees

Putter: It is a universal angle of use from 3 to 4 degrees.
