Hand tools are the traditional basic tools used by workers in Bell Metal Industry. The current research was undertaken to study the occupational problems related to the hand tools used by these workers from the districts of Assam. A descriptive survey was conducted on 30 male artisans involved in forging activity using an interview and questionnaire tool; in order to know the hand tool design related problems. The intervention study was carried out for five parameters of the tool-hammer for redesigning: rough finish, weight of tool, contact point stress, handle length, and force exerted while using the tool. Based on the design problems in the existing hammer, 2 prototypes were developed and tested. The McNemar test further supported that the new prototype design I and II were better and significantly reduced the problems associated with the existing hammer design.
