Definition: An iron on which the clubhead features a thin face with a hollowed-out area on back, distributing the weight around the perimeter (contrast with "blade" or "muscleback"). The weighting of cavity back (which can be forged, but are usually cast) clubs allows for a larger sweet spot, which provides help on mis-hits. Cavity back irons are preferred by mid- to high-handicap players, but many low-handicappers and touring pros use cavity backs, too, for their forgiving properties. Cavity backs fall into the category of "game improvement clubs."
