         9 . A method as defined in  claim 8 , wherein the shock-absorbing elastic polymer material extends from the back portion to the face portion within the interior cavity portion. 
     
     
         10 . A method as defined in  claim 8 , wherein the body portion comprises a first material and the second set of mass portions comprise a second material, the first material being a metal material and the second material being a non-metal material. 
     
     
         11 . A method as defined in  claim 8 , wherein the body portion comprises a first material and the second set of mass portions comprise a second material, the second material having a density greater than the first material. 
     
     
         12 . A method as defined in  claim 8 , wherein attaching the face portion to the body portion comprises welding or brazing the face portion to the body portion. 
     
     
         13 . A method as defined in  claim 8 , wherein each of the first set of mass portions is associated with a first height and each of the second set of mass portions is associated with a second height, and wherein the first height is shorter than the second height. 
     
     
         14 . A method as defined in  claim 8 , wherein each of the first set of mass portions is associated with a first height of less than or equal to 3.175 millimeters (0.125 inch) and each of the second set of mass portions is associated with a second height of less than or equal to 7.62 millimeters (0.3 inch).
