Jaipur, Udaipur, and Sirohi are the main centres for making swords and shields which are essential for rituals; the weapons are made by damascening. In the technique of damascening, the design is first chased on the iron or steel surface with a sharp chisel. Gold or silver wire held in one hand within the groove is hammered in with the other hand. The hammering is done so skilfully that the wire is actually welded to the metal surface.
