Iron is a club with a flat head. The standard set of best golf irons for mid-handicappers includes 3 to 9 irons as well as pitching-wedge and sand-wedge. Pitching-wedge (PW) is the iron following in the set of the best golf irons for mid-handicappers after the number 9, and it is usually used for strokes on the green. Sand-wedge (SW) – the iron which is the next in the set after pitching-wedge. Most often is used for knocking the ball out of the bunkers.
