Question: What was known about steel in ancient America?

The steel of the Book of Mormon is probably not modern steel. Steel, as we understand today, had to be produced using a very cumbersome process and was extremely expensive until the development of puddling towards the end of the 18th century. Even in ancient times, however, experienced smiths could produce steel by heating and hammering pig-iron or, earlier still, the never-molten iron from a bloomery to loose the surplus of carbon to get something like elastic steel. Early smiths even knew that by quenching hot steel in water, oil, or a salt solution the surface could be hardened.

Any Mesoamerican production likely depended upon the first method, which requires lower temperatures and less sophistication. Laban's "steel sword" is not anachronistic; Middle Eastern smiths were making steel by the tenth century B.C.[1]
