A golf club head includes a body, a first polymeric insert, and a second polymeric insert. The body includes a face, a sole, and a rear wall that collectively define an undercut volume. The first polymeric insert is provided within the undercut volume to define a sealed cavity within the undercut volume; and, the second polymeric insert is secured to the body and defines an open cavity extending from the rear wall toward the face.

A ball striking device, such as an iron-type golf club head, includes a face having a ball striking surface and a body connected to the face. The body has a sole surface extending rearward from a leading edge of the face, and a toe surface extending rearward from a toe edge of the face. The sole surface configured to confront the playing surface. The iron-type club head may have an elongated channel extending from a heel side in the sole member to an end point within the toe surface. The elongated channel is recessed from the sole surface and toe surfaces and is spaced from the leading and toe edges of the face. The iron-type club head may also have a plurality of weighting elements that are adjustable by the user.

A hollow golf club head includes a metallic body, a club face, and a polymeric insert that cooperate to at least partially define a closed internal cavity. The metallic body includes a sole, a topline, and a rear wall defining an opening, with the rear wall being disposed between the topline and the sole. The club face is disposed between the topline and the sole, and on an opposite side of the sole from the rear wall. A strut extends across the opening and is secured to the body, and a polymeric insert covers the opening and is secured both to the body and to the strut.

Putter heads have a ball striking face portion and a rear body portion (as one or more parts). These putter heads may have a D/B ratio of at least 0.425 (where B is the overall breadth dimension and Dis the depth of the center of gravity). Some putter heads may include: (a) a ball striking face body member having a ball striking face with plural openings defined in its central portion; (b) a polymeric material mostly located behind an exterior surface of the ball striking face, wherein a portion of the polymeric material is exposed at the exterior surface of the ball striking face through the openings; and (c) a rear body member engaged with the ball striking face body member. Rear body members or portions thereof can be interchanged to allow for customization and/or better fitting of the putter to the user's putting stroke and/or tastes.
