摘要： A handle includes an inner core and a gripping portion disposed around the periphery of the inner core, and at least one chamber is formed between the inner core and the gripping portion. A hammering tool includes the handle. When the hammering tool is used for striking, the internal damping slot of the hammerhead can use a damping material as a first buffering and absorb the vibration and impact force of the hammerhead, which are then delivered to the inner core of the handle, the inner damping layer and its chamber serve as a second buffering and absorb the vibration and impact force delivered from the inner core of the handle, and finally, the outer damping layer serves as a third buffering and absorbs the vibration and impact force delivered from the inner damping layer.
