The question Any notable battles fought with steel vs. bronze weapons?, more precisely the comment to this answer to the tone of "ah, but that was mainly a chariot battle...", piqued my interest.
As far as I know my history, the predominant weapons of the Bronze / Iron Age were spears and bows. Isn't it correct that the sword was, mostly, a nobleman's sidearm (as it was rather expensive to produce)?
This would render the whole "how would a bronze sword fare against an iron / steel sword" issue mostly academical.
How common, or uncommon, were sword-versus-sword combats on the ancient battlefield?
I am not talking duels or the like, but warfare.
