We find similar trend at Ujjain. The first phase (750-550 BC) shows arrow-heads, spearheads, crowbars, spades, choppers, knives and presumably saws of iron. There is a fortification built of hard yellow clay and black cotton clay which must have been dug and processed by hard metal. A fairly well-preserved blade of an iron spade has been found in the body of the rampart.
