ABSTRACT:
An improved leather marking tool which incorporates both the hammer and the punch into a single unit, the improvement being directed to the keying of the drive shaft of the unit in order to prevent rotation and incorporating a structure at the end of the drive shaft which permits such to cooperate with a plurality of different marking heads so marking heads can be used interchangeably.
