Abstract
A hammer that includes a handle and a head is provided. The head disposed on an upper end of the handle. The handle includes a core member; a rigid material layer molded on the core member; and a grip member molded on at least a portion of the rigid material layer. The grip member includes a first elastomeric material layer molded on the rigid material layer and a second elastomeric material molded on the first elastomeric material layer. The head has an eye portion extending through the head. The handle has at least a portion of its upper end extending into the eye portion. An epoxy resin material is positioned within the eye portion and is at least partially disposed between the handle and the head to secure the handle to the head. An elastomeric portion is at least partially disposed between the handle and the head.
