A golf club is a kind of golf bat used for striking the ball in a series of holes. The clubs are usually made of wood, iron or a hybrid of both the elements. The clubs have loft present at the end of the shaft that determines the trajectory of the ball and the velocity with which the club can strike it. All the clubs have a number marked on them. The higher golf club number indicates the shorter shafts and higher lofts and it also gives the ball a higher but shorter trajectory.
Each club has a basic construction including a long shaft, grip and a club head. Earlier, the shafts were made from different types of woods such as ash, orangewood, purpleheart, blue-mahoo and hickory. The heads of the golf clubs were usually made from the woods such as apple, pear, dogwood, beech and persimmon. But the modern shafts are manufactured from steel, titanium and other metals or strong carbon fibre to improve the accuracy of golfers. The grips of the golf clubs are made from rubber or leather.
The rules of golf set by the R&A (Royal and Ancient Golf Club of St Andrews) and the USGA (United States Golf Association) states that a golfer can have a maximum of 14 clubs in his/her bag. The most widely used set of golf clubs includes a driver, a fairway wood, a set of 7 numbered irons, a sand wedge and a putter. Other than these 12, two other clubs can be chosen by the golfers based on their preference. The rules also state that none of the clubs should have a concave face. There are many other regulations regarding the shape and physical features of the clubs which are permitted to be used during an official tournament.
