PROBLEM TO BE SOLVED: To solve the problem of the conventional hand hammer that since the area of a striking part occupying in the whole is small, sometimes a failure in hammering is caused, or hammering is performed by a grip part by mistake to damage a grip 2. SOLUTION: The striking part 1 is made longer along the direction of the grip 2, whereby failure in hammering or damage to the grip can be reduced. COPYRIGHT: (C)2005,JPO&NCIPI
