“The hilt thereof was of pure gold, and the workmanship thereof was exceedingly fine, and … the blade thereof was of the most precious steel”
1 Nephi 4:9
The sword of Laban is one of the most iconic objects in the Book of Mormon. It was passed down from generation to generation (Mosiah 1:16) and was apparently still being used in battle even during the time of King Benjamin (Words of Mormon 1:13). In June of 1829, the Lord told Oliver Cowdery, David Whitmer, and Martin Harris: “you shall have a view of the plates, and also of the breastplate, the sword of Laban” (Doctrine and Covenants 17:1). David Whitmer stated that this prophecy was soon fulfilled.
Yet the Book of Mormon does not give much information about how the sword looked. Nephi simply stated that “the hilt thereof was of pure gold, and the workmanship thereof was exceedingly fine, and … the blade thereof was of the most precious steel” (1 Nephi 4:9).
Thanks to archaeological discoveries in recent decades, however, we now have more information about what this sword might have looked like. In the 1980s, archaeologists discovered a sword that has many similarities to Laban’s sword. It was found in Jericho, a city near Jerusalem, where Laban was from, and it dates from around 620 BC, when Laban lived. Most surprising of all, it was made out of steel, just like Laban’s sword. Most surviving swords from this time period in the ancient Near East were made out of iron or bronze, so this sword, made out of steel, is a close match to the sword of Laban described in the Book of Mormon.
The Jericho sword is three feet long and three inches wide, which is surprisingly long for the ancient Near East. However, it would have been much more difficult for Nephi to cut off Laban’s head if the sword were any shorter than this, so it is likely that Laban’s sword was roughly this size as well.
Another interesting detail is that, according to a metallurgical study of the Jericho sword, “the iron was deliberately hardened into steel.” Ironworkers can accidentally produce lower-quality steel as part of the smelting process, but this iron was intentionally hardened into high-quality steel. If the same was true of Laban’s sword, this could explain Nephi’s comment that it was made of “most precious steel” (1 Nephi 4:9).
Finally, it is possible that the sword of Laban had words engraved on it. Joseph Smith and Oliver Cowdery once saw a large room which contained many plates. “The first time they went there the sword of Laban hung upon the wall; but when they went again it had been taken down and laid upon the table across the gold plates; it was unsheathed, and on it was written these words: ‘This sword will never be sheathed again until The Kingdoms of this world become the Kingdom of our God and his Christ’.”
It is hard to know if this was a somewhat symbolic vision, a vision of a real location with real items, or an actual cave which they visited in upstate New York. In any case, if they were seeing the actual sword of Laban, either in vision or in person, then this gives us one more detail about its appearance.
Before archaeologists discovered the long steel sword in Jericho, the description of the sword of Laban in the Book of Mormon may have seemed too fantastic to be true. Some people laughed at the notion of a steel sword in Jerusalem in 600 BC. Similarly, the idea that an ancient Near Eastern sword could be long enough for Nephi to decapitate Laban in the manner described in the Book of Mormon also seemed unbelievable. And then, 150 years after the Book of Mormon was published, archaeologists discovered an artifact that showed that the Book of Mormon’s account was not so unbelievable after all.
According to Matt Roper, “One of the earliest criticisms of the Book of Mormon was that Laban could not have had a steel sword blade, because steel was not invented until much later.” So for roughly 150 years, people who believed in the Book of Mormon had to do so with this unanswered question lingering in the background. However, this question was eventually answered, and those who believed in the Book of Mormon, Sword of Laban and all, were eventually vindicated. Archeology just hadn’t yet caught up to the Book of Mormon.
This situation can offer valuable lessons for us today. When we have questions about the Book of Mormon that we do not have good answers to right now, we should simply remember the Sword of Laban, and know that the answers will come eventually. Neal Rappleye, commenting upon Sam Wineburg’s illuminating case study on historical thinking, has explained that “Wineburg found that mature historical thinkers displayed patience with the unknown. They were able to call attention to apparent contradictions without immediately seeking to resolve them.” Although this is uncomfortable, “mature historical thinkers ‘sat with this discomfort’ as they continued to review additional sources.” In the process, “they exercised what Wineburg called the ‘specification of ignorance’: a practice of identifying when you do not know enough to understand something.” One must then conclude with “‘cultivating puzzlement’: being able ‘to stand back from first impressions, to question … quick leaps of mind, and to keep track of … questions that together pointed … in the direction of new learning.’” 
If we will put some of our questions aside, for now, knowing that they will be answered eventually, we can develop a mature faith that will stand the test of time.

 Emphasis added. As it turns out, one could have found precious steel like this even from a few centuries earlier: “It seems evident that by the beginning of the tenth century B.C. blacksmiths were intentionally steeling iron.” Robert Maddin, James D. Muhly and Tamara S. Wheeler, “How the Iron Age Began,” Scientific American 237, no. 4 (October 1977): 127. “Wrought iron heated in contact with hot charcoal (Carbon) at high temperatures produces carbonized iron or steel which is more malleable than cast iron.” King and Stager, Life in Biblical Israel (Louisville, KY: Westminster/John Knox Press, 2001), 169.

 They would have held onto their beliefs in the face of critics saying things like this: “This is the earliest account of steel to be found in history.” E. D. Howe, Mormonism Unvailed (1834), 25–26. “Laban’s sword was steel, when it is a notorious fact that the Israelites knew nothing of steel for hundreds of years afterwards. Who but as ignorant a person as Rigdon would have perpetrated all these blunders?” Clark Braden in Public Discussion, 1884, 109. “Laban is represented as killed by one Nephi, some six hundred years before Christ, with a sword ‘of the most precious steel,’ hundreds of years before steel was known to man!” Daniel Bartlett, The Mormons or, Latter-day Saints (1911), 15. “[The Book of Mormon] speaks of the most ‘precious steel,’ before the commonest had been dreamt of.” C. Sheridan Jones, The Truth about the Mormons (1920), 4–5. “Nephi . . . wielded a sword ‘of the most precious steel.’ But steel was not known to man in those days.” Stuart Martin, The Mystery of Mormonism (1920), 44. “Laban had a steel sword long before steel came into use.” George Arbaugh, Revelation in Mormonism (1932), 55. “Every commentator on the Book of Mormon has pointed out the many cultural and historical anachronisms, such as the steel sword of Laban in 600 B.C.” Thomas O’Dea, The Mormons (1957), 39. “No one believes that steel was available to Laban or anyone else in 592 B.C.” William Whalen, The Latter-day Saints in the Modern World (1964), 48.
 Ultimately, those who kept their faith in the Book of Mormon were amply vindicated, as many examples of ancient steel can now be found from the Near East.
