An important variation in different clubs is loft, or the angle between the club's face and the vertical plane. It is loft that makes a golf ball leave the tee on an ascending trajectory, not the angle of swing; virtually all swings contact the ball with a horizontal motion. The impact of the club compresses the ball, while grooves on the clubface give the ball '''backspin''' (A well-struck golf shot will result in a large amount of backspin that will carry the ball higher into the air and further. Backspin also helps with distance control, as if there is enough backspin, the ball will "check" if it lands on the putting surface, and sometimes even creep backwards (in the opposite direction that the ball was flying) upon landing.). Together, the compression and backspin create lift. The majority of woods and irons are labeled with a number; higher numbers indicate shorter shafts and higher lofts, which give the ball a higher and shorter trajectory.<br>

Used for pushing and rolling the golf ball from close distance along on the green or apron towards the cup. Every lady golfer must have this type of golf club.
**'''Utility & Hybrid Ladies Golf Clubs'''
Hybrid ladies golf clubs are a cross, with a clubhead that combines the features, characteristics and benefits of an iron and a wood. Many women replace their 2, 3, and 4-irons with these types of golf clubs.

The grip of the golf club is important because it connects the club to the golfer's hands. According to the rules of golf, recognized by both ruling bodies, the grip has to be round, without obvious bumps, lumps or hollows.
The shaft of the golf club connects the grip to the head and, like the grip, must be basically round in cross section. Most modern golf club shafts are made of either steel or a carbon-fiber and resin composite. Carbon fiber has the advantage of being lighter than steel, but clubs with carbon-fiber shafts also tend to be more expensive.
The head of the golf club is where all the energy of the swing is transferred to the golf ball. There is more variation in the appearance of golf club heads than there is in either shafts or grips, but all the variations fall into one of three broad categories: the heads of woods, irons and putters.
*'''Parts of Club Head:'''<br>
[[Image:head parts.jpg|1000px|centre|thumb|Parts of Head]]
The head of the golf club has several parts: the '''Hosel''', where the head connects to the shaft; the '''Face''', which actually strikes the ball; the '''Sole''', which is the part closest to the ground; and the '''Back''', which is on the side opposite the face.
