Abstract

A golf club head for an iron-type club is provided. The club head includes a striking face, a slotted member and a first weight member. The striking face has a surface configured to engage a golf ball. The slotted member is positioned behind the striking face. The slotted member includes a slot network having at least two intersecting slots and at least three ends. The first weight member slidably engages the slot network to vary the position of the center of gravity of the golf club head with respect to the striking face.
