A correlated set of golf clubs of the type commonly referred to as irons is disclosed. Various dimensions are the same for all club heads of a set even though loft and lie angles A and C are different for each. Weight is controlled by the depth of a cavity in the rear of the club head. A slope angle B of the sole is increased from a small negative value to a larger positive value as loft is increased from a minimum to a maximum, with substantially zero slope for a midrange club of the usual set of clubs numbered 1 to 9.
