The back is an area of the clubhead that is located, well, at the back. On irons, it is usually the area that will see marketing materials applied or engraved from the club’s manufacturer, notably the make and model of the club.
Clubs of the blade variety will see flat back surfaces while more forgiving clubs will see a deep cavity (cavity-back) and even weights applies to the bottom of that cavity.
