1. A golf club head comprising:
- a heel;
a toe;
a striking face;
a rear cavity;
a sole;
a sole bar proximate the sole;
a slot formed proximate the sole bar, the slot extending longitudinally between the toe and the heel, the slot extending from the sole at least partly through the sole bar to the rear cavity; and

Abstract
A golf club head is disclosed that comprises a body having a striking face and a sole, wherein a recess is formed in the sole. An insert is located within the sole recess, the insert including a core and an intermediate layer that at least partially separates the core from the recess wall. The intermediate layer has a hardness and a modulus of elasticity that are less than that of the core, such that when the golf club head is used to strike a golf ball, the resulting vibrations are dissipated by compression of the intermediate layer and movement of the core with respect to the intermediate layer.

22. An iron-type golf club head comprising:
-
a body having a striking face, a rear cavity, and a sole, wherein a recess is formed in the sole, the recess having a recess wall and including an elongated slot formed in the sole, extending from a heel of the club head to a toe of the club head;
an insert located within the sole recess, the insert including a core and an intermediate layer that at least partially separates the core from the recess wall;
the core of the insert comprises a substrate having interstices; and
the intermediate layer of the insert comprises a separate material that is disposed within the interstices of the substrate and that is located at least partially between the substrate and the recess wall; and
wherein the intermediate layer has a hardness and a modulus of elasticity that are less than that of the core, such that when the golf club head is used to strike a golf ball, the resulting vibrations are dissipated by compression of the intermediate layer and movement of the core with respect to the intermediate layer.

23. An iron-type golf club head comprising:
-
a body having a striking face, a rear cavity, and a sole, wherein a recess is formed in the sole, the recess having a recess wall; and
the sole recess includes an elongated slot formed in the sole, extending from a heel of the club head to a toe of the club head;
an insert located within the sole recess, the insert including a core and an intermediate layer that at least partially separates the core from the recess wall;
the core of the insert comprises an elongated substrate; and
the intermediate layer of the insert comprises a sleeve that at least partially surrounds the substrate, the sleeve being disposed between the substrate and the recess wall; and
wherein the intermediate layer has a hardness and a modulus of elasticity that are less than that of the core, such that when the golf club head is used to strike a golf ball, the resulting vibrations are dissipated by compression of the intermediate layer and movement of the core with respect to the intermediate layer.
