Numbered clubs, also known as IRONS, are a type of golf club used to hit the ball from the tee box or fairway. They are typically made of metal and have a long shaft with a flat angled head. The numbered clubs range from 1 to 9, with each number representing a different loft angle and distance. The higher the number, the higher the loft angle and the shorter the distance. IRONS are essential for golfers of all levels and are used to hit the ball accurately and with control.
