Steel Arrowheads in Pre Columbian North America?

The Book of Jarom, verse 8 (Book of Mormon)
And we multiplied exceedingly and spread upon the face of the land and became exceedingly rich in gold, and in silver, and in precious things and in fine workmanship of wood in buildings, and in machinery, and also in Iron and Copper, and brass and steel, making all manner of tools of every kind to till the ground, and weapons of war– yea the sharp pointed arrow, and the quiver, and the dart, and the javelin, and all preparations of war.
So… anyone find any of these sharp pointed arrows made of steel, copper, brass or iron? To this day you can find spear heads, and arrow heads made of different types of stone scattered all over America, but you don’t see anything made of steel. Which brings up another point. The Mormons would like you to believe that by steel they mean bronze. In older English, before the wide spread smelting of steel as we know it, steel was a word used for bronze distinguishing it from copper. However there is no distinction in the ancient languages of the near east between copper and bronze, the word in Hebrew for instance is the same. If you were to bring bronze to the junk yard, even today, they give you the price for copper. So you are left with a bit of a conundrum here of trying to explain this away as meaning bronze. All that aside though, you have some seriously hard questions to answer as far as archeology is concerned.
