发明名称 Iron-type golf clubs
摘要 The present invention is directed to a number of customized sets of iron-type golf clubs selected from a relatively small number of clubs. The multiple custom-fitted iron sets can be achieved by pivoting these sets off a common 6-iron. In a preferred embodiment, a portfolio of clubs contains seventeen forged iron-type golf clubs, wherein the clubs are a blended collection of oversized cavity back-type clubs, mid-sized clubs, and standard-sized muscle back-type clubs, which can be configured to create at least four custom-fitted iron sets pivoted off a common 6-iron.
