Well, it was told by my teacher, with years of practice in metal works,
when I asked him. But than again maybe he's getting old? :=)

I know for fact, of my owm experience, that one cannot hammer gold
in a hot condition. The same goes for silver too. This can only be
done with iron or steel. If we are able, and that's wat my response
was all about, to make golden knives of 23.99 carat, it is no mysterious
thing only the Sumerians were able to.
