A set of golf clubs, has irons with their loft angles decreasing inversely proportionately to the lengths of shafts and their grounding edges formed on their soles such that they are swept back or regressed inversely proportionately to the lengths of the shafts. Thus, the longer irons for hitting up the ball are allowed to have their faces confront the ball accurately, and the shorter irons for hitting down the ball are allowed to have their faces hit it through.
