The jobbing hammer is an essential piece of kit for any jeweller or craftsperson working on small scale projects.  Great for forming curves and domes in metal with doming blocks and punches,  or for hammering textures to metal surfaces. Sometimes referred to as a Ball Pein or Ball Peen hammer, the two heads of the hammer consist of a ball pein at one end, and a flat head at the other. 1 oz (28g)
