People apparently have forgotten what the Book of Mormon actually says. Nephi didn't make the steel bow - he had it when he left Jerusalem. He
broke the steel bow, and had to make a wooden one to use to hunt animals for food.
What's interesting to me is that he broke his steel bow, and then in the description of him making a new wooden bow, he also had to make new arrows. What was the matter with his old arrows? Did he snap them all in frustration after breaking his bow?
I think the steel bow thing is damning of the Book of Mormon.
From 2 Samuel 22:35 in the Old Testament:
He teacheth my hands to war; so that a bow of steel is broken by mine arms.
Now from 1 Nephi 16:18 in the Book of Mormon:
And it came to pass that as I, Nephi, went forth to slay food, behold, I did break my bow, which was made of fine steel; and after I did break my bow, behold, my brethren were angry with me because of the loss of my bow, for we did obtain no food.
I agree with Hamblin that it's pretty obvious that the reference to a steel bow in the Book of Mormon is borrowed from the Old Testament. Where we differ is that Hamblin will argue that the "steel bow" in the Book of Mormon was in fact really what the "bow of steel" was in the Old Testament, namely this bronze-reinforced composite (wood, sinews, etc.) bow.
I would argue that it's way more likely that the author of this passage in the Book of Mormon simply didn't know that "bow of steel" didn't really mean a bow, made from steel. He therefor lifted this "... so that a bow of steel is broken by mine arms." from the Old Testament as a sort of "me too!" rip-off, to enhance how awesome Nephi was - he did the same thing referenced in the Old Testament - how awesome is that?
The KJV odd translation of bronze to steel is, I think, an artifact of the particular English scholars at that particular time, and I don't see how that oddity would have manifest itself through the Hebrew text, as revealed to Joseph Smith through the magic rock in the bottom of his hat, written on the ethereal parchment by God. That's simply asking too much.
Mormonism ceased being a compelling topic for me when I finally came to terms with its transformation from a personality cult into a combination of a real estate company, a SuperPac, and Westboro Baptist Church. - Kishkumen
