Method of manufacturing hammer

A method of manufacturing a hammer having a hammer head with a head face formed on one end of the hammer, and an adapter with an inner adapter face formed on the inner side of the adapter and a working face formed on the opposite side of the adapter for striking a workpiece, said hammer head and said adapter being secured to each other through a resilient connecting member and with said head face and said adapter inner face being in contact with each other in a predetermined positional relationship therebetween so that upon impact applied on said working face said adapter is rotated about its central axis with respect to said hammer head against the resilient force of said connecting member in a direction from a predetermined position, and upon removal of the impact force said adapter returns automatically to its original position by means of the resilient force of said connecting member, comprising the steps of:

• a. applying lubricant to the contact area of said head face and said adapter face;
• b. positioning said hammer head and said adapter to each other with said head face and said adapter inner face in contact with each other in said predetermined positional relationship;
• c. applying a bonding agent onto adjoining peripheral portions of said hammer head and said adapter to temporarily bond said hammer head and said adapter to each other;
• and
• d. providing heat melted thermo-meltable elastic material over peripheral portions of said hammer head and said adapter including therebetween said bonding agent which has been applied to said adjoining peripheral portions so as to form said resilient connecting member with said elastic material to permanently secure said hammer head and said adapter to each other.
