Golf clubs and golf club heads
First Claim
1. A system for a head of an iron-type golf club, the system comprising:
- an iron-type body extending from a shaft-attachment structure, the iron-type body having a front surface and a back surface, the back surface including a back-surface peripheral edge, a raised central portion at the center of the back surface, integrally formed together with the iron-type body, and a recessed area, the recessed area extending from the raised central portion to the back-surface peripheral edge along at least a top portion of the back-surface peripheral edge of the iron-type body; and
a first mass member releasably attached to the back surface of the iron-type body,wherein the first mass member is positioned within the recessed area and extends from the raised central portion to the back-surface peripheral edge along the top portion of the back-surface peripheral edge of the iron-type body, andwherein a back surface of the first mass member is flush with a back surface of the raised central portion.

Abstract
A golf club includes a golf club head having a body, a ball-striking face member and one or more mass members. The body extends from a shaft-attachment structure. The ball-striking face member is located on a front surface of the body. The body is configured to releasably accommodate a first mass member in a first region on its back surface and a second mass member in a second region on its back surface. At least one of the first and second mass members may be releasably attached to the back surface. The ball-striking face member may have an average density that is less than the average density of the body. The mass members may have an average density that is more than the average density of the ball-striking face member and/or of the body. The mass distribution of the club head may be customized via the selection and attachment of a particular mass member. The golf club head may be an iron-type golf club head.

22. A system for a head of an iron-type golf club, the system comprising:
-
an iron-type body extending from a shaft-attachment structure, the iron-type body having a front surface and a back surface, the back surface having a raised central portion at the center of the back surface, integrally formed together with the iron-type; one or more first mass members releasably attached to the back surface of the iron-type body, the one or more first mass members having a first thickness profile and a first mass distribution and extending along substantially all of a back surface peripheral bottom edge, and wherein the raised central portion extends from the one or more first mass members to a peripheral top edge, a heel edge, and a toe edge; and one or more second mass members configured for interchangeable attachment with the one or more first mass members, the one or more second mass members having a second thickness profile different from the first thickness profile and a second mass distribution different from the first mass distribution, wherein a back surface of the one or more first mass members or the one or more second mass members is flush with a back surface of the raised central portion. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
