Arthur Chris Eccel argues against the Book of Mormon based on Nephi having a "steel bow"; claims Joseph did not know how ancient bows might have been constructed.

Although our focus is on Pre-Columbian America, it is worth noting that the steel bow of Nephi (1 Nephi 16:18) is highly improbable. Actually, steel bows have exited for perhaps as much as two thousand years. During thirty years in the Semitic Middle East, I systematically collected premodern ethnographic artifacts, which eventually came to be my personal and very focused museum of same, now on display in my home in Hawaii. I have an antique steel bow, made of spring steel with a silver layer on the front side of the bow and small inlaid gold nuggets. An almost identical one is on display in the museum in Riyadh, Saudi Arabia, dated to the nineteenth century. Although this may have been a ceremonial bow, early steel bows were used in hunting and warfare. The earliest development of steel bows appears to have been in India. There is indirect evidence that Indian metallurgists were experimenting with them perhaps as early as the third century BCE. Such a bow constructed in the seventh century BCE is extremely unlikely. In an intriguing verse (1 Nephi 16:21) Nephi says that his brothers’ bows had “lost their springs.” This appears to be a double misconception, first of how an ancient bow might have been constructed, and second, the date of the emergence of spring steel. The existence of Steel swords in that century, such as the sword of Laban, has to be addressed cautiously. Some sort of sword made of iron is attested perhaps as early as the sixth century BCE. Could a ferrous bow have been made eighty years earlier? We cannot rule this out. Furthermore, since early forms of steel existed, the best might be called “most precious steel” at the time, even if it would be called mediocre at best today. The steel bow found in Wyoming, now in the Jim Gatchell Museum in Buffalo, is a perfect unrusted condition and considered to have been blacksmith-forged in the nineteenth-century.
