Many golf irons feature a cavity at the back of the club head, as this technology is known to provide a much more forgiving playing experience. This is because the weight has been removed from the centre of the club and has been pushed to the club’s edges, resulting in more forgiving shots for players who catch the ball off-centre. This is in comparison to forged irons (or “muscle back irons”) which do not feature a cavity and are better suited to lower handicap players. Several Cobra golf irons have hollow backs if you’re looking for a new, forgiving set.
