Or is it possible that the emphasis was intentially dislocated from the center of weight? - Bus this wouldn't make any sense to me.

Hi Andi,

There is of course more than one possibility how these iron cores could have been made.
All I can tell with authority is that mine was cast in a mold, and hammering them to such a smooth and perfect surface is just out of my mind (without intending to brag, I got a lot of smithing experience).
I will post images soon though.
