Abstract
An apparatus can comprise a body with a receptacle, and a multi-density weight. The multi-density weight can comprise a first weight component with a first density, an inner portion and a periphery around the inner portion, and a second weight component with a second density and secured to the inner portion of the first weight component. The body, and the first and second weight components can comprise materials different from each other. The receptacle can have a receptacle base and a receptacle wall. The second weight component can comprise a material having a weld-averse trait with respect to the body. The surface of the body can be proximate to at least one of a hosel region, an upper toe region, a lower toe region, a heel region, a backside region, an upper-half region, or a lower-half region of the body. Other embodiments and related methods are also disclosed herein.
