NO that is not what I'm saying.
If they worked with Iron could they not have found the secret of steel. I understand you are saying they didn't know how to refine Iron.
I can give you that maybe Nephi found the secret of steel but I doubt that he did. Why have iron when you could have steel. Plus, how to manufacture enough of it for whatever purpose he needed it for. It's a pretty complicated process.
Please tell us where such advanced metallurgy has been identified with the bom age in the americas (provided you think the bom lands were in america). Mining and smelting leave things that are nearly indestructable over the short period of time we are talking here - mines, slag, retorts, charcoal kilns, etc. Evidence of such a culture is completely absent in the Americas bm during the bom era. If they had steel - why is FARMS/Maxwell trying to convince all that the nephites REALLY had clubs with chips of flint in them for "STEEL" swords eh?
