Irons feature thin clubheads and grooved faces. Beginner usually uses cavity back style and experienced users might choose muscleback or blade style or iron.

 

A blade style features a full back on the rear of the clubhead and a cavityback is the rear of the clubhead is hollowed out. A typical set of irons will include 3-iron and 8 clubs. Each club has a little less loft than the next and a little longer shaft length than the next and each club goes a little father than the next. Basically that means a 3-iron has less loft and longer than a 4-iron.
