This is a reproduction of an antenna hilted knife from the urnfield period. It's based on an original found in Csóka, Serbia. It's 20cm long, made from 12% tin bronze and with a workhardened edge. I previously cast these in a soapstone mould. The mould was lost, so I made a model from one of the casts, where I had to undo the curve and thicken up the edge, so that I could cast them again and hammer them to the correct shape after casting.
