David, Thanks very much for your interesting, thorough reply. Yes, there are also a few references to "brown" swords. > 'Metal free' or 'metal clear' refers to the difference between naturally occurring free iron and iron refined from ore ('metal brown') - or to the iron derived from different ores. Pyrites, haematite and another ironstone ore (can't remember, I knew all this once from my father) require different extraction processes and there were very rare occurrences of free iron - maybe meteorites...
The same is true of good kitchen knives-- of which i have a couple. Good swords did not rust(ditto armour) but went dark and stayed sharp.
