I also know enough metallurgy to be able to manufacture charcoal, which can burn hot enough to smelt iron. I couldn't work the damn stuff, but just being able to make cast iron swords would probably impress the locals.
Cast iron is rubbish for making swords. You'd not impress bronze age smiths
or warriors with one of those.
Now, if you were able to find, mine, refine, smelt and work iron-ore to a
high standard (all on your own, starting from scratch) then that might be
different. Even then, though, the early iron swords had very little advantage
over the best of the bronze ones, so to impress the locals (and especially
their warriors) you'd need to set the bar for yourself very high - like carbon-
steel high.
The techniques used by bronze age smiths were sophisticated enough that
modern researchers still have trouble accurately reproducing them (this, for
example, is one of the reasons why
authentically cast reproduction
bronze spearheads are almost unheard of).
Personally I'd think more modestly. I could tell more spellbinding stories than
anyone else ("A long time ago, in a galaxy far, far away..."), sing more
enthralling songs (Bronze Age rap), paint and draw with uncanny realism
(using modern composition and perspective). Once over the hurdle of
immediate survival, I think I'd get along OK. The "culture shock" would be
absolutely mind-buggering though.
