Abstract: A hammer includes a rigid elongated support structure, a head carried at one end of the support structure, and a manually engageable gripping portion. An end of the elongated support structure includes a pair of vibration-receiving portions terminating in spaced apart relation with respect to each other and spaced from each other in a direction parallel to a swing plane of the hammer. The manually engageable gripping portion is formed from a resiliently deformable material molded around a portion of the support structure including the vibration-receiving portions so as to fill the space between the vibration-receiving portions. Vibration forces acting in a direction parallel to the swing plane of the hammer are generated by striking a striking surface of the head against an object.

Abstract: A composite split head percussive tool including a rigid load bearing framework which carries a non-load bearing head assembly. The non-load bearing head assembly comprises a pair of axially aligned split heads that are interconnected to each other by an elastomeric link. The elastomeric link is encased and fixed within the tool body. During use of the tool, the elastomeric link acts as a dampener that suppresses the struck end rebound of the tool. When one head is struck against a surface, the elastomeric link allows the unstruck head to move toward the struck head and provide a secondary blow that inhibits the tool's struck end from bouncing away from the surface thereby providing the hammer with a unique "dead-blow" characteristic.
