I find myself enjoying the ramblings course material of a professor at Kiel University which explores the material science and all the other "need-to-know" information on swords and metallurgy, and while Gloranthan iron has little to do with the material described in these lecture notes, the discourses about swords, history etc. are written in a somewhat wry and quite informative style. The text makes a point of connecting the art of making (and drinking) beer with the emergence of swords, for instance... and links to a scientific article on the earliest beer recipe written in proto-cuneiform, even older than the Gilgamesh epic.
The material lacks of course the link to the Storm element that is special about Gloranthan swords. But the violence implication is in the text.
