Woods are long-distance clubs, meant to drive the ball a great distance down the fairway towards the hole. They generally have a large head and a long shaft for maximum club speed. Historically woods were made from persimmon wood although some manufacturers—notably Ping—developed laminated woods. In 1979, TaylorMade Golf introduced the first metal wood made of steel. Even more recently manufacturers have started using materials such as carbon fiber, titanium, or scandium. Even though most "woods" are made from different metals, they are still called "woods" to denote the general shape and their intended use on the golf course. Most woods made today have a graphite shaft and a mostly-hollow titanium, composite, or steel head, of relatively light weight allowing faster club-head speeds. Woods are the longest clubs and the most powerful of all the golf clubs. There are typically three to four woods in a set which are used from the tee box and, if on a long hole, possibly for the second or even third shot. The biggest wood, known as the driver or one wood, is often made of hollowed out titanium with feather-light shafts. The length of the woods has been increasing in recent decades, and a typical driver with a graphite shaft is now 45. 5 inches (1,160 mm) long. The woods may also have very large heads, up to 460 cm3 (28 cu in) in volume (the maximum allowed by the USGA in sanctioned events; drivers with even larger club-head volumes are available for long-drive competitions and informal games). The shafts range from senior to extra-stiff depending upon each player’s preference.
