Of this particular sword, the prophet Nephi writes
"...and as I came near unto the house of Laban I beheld a man, and he had fallen to the earth before me, for he was drunken with wine. And when I came to him I found that it was Laban. And I BEHELD HIS SWORD and I drew it forth from the sheath thereof; and the hilt thereof was of pure gold, and the workmanship thereof was exceedingly fine, and I saw that THE BLADE THEREOF WAS OF THE MOST PRECIOUS STEEL. And it came to pass that I was constrained by the Spirit that I should kill Laban..." -- 1 Nephi 4
Nephi later writes, after they get to America, and the family splits in two (Nephites/Lamanties)
"...I, Nephi, did take the sword of Laban, and AFTER THE MANNER OF IT DID MAKE MANNY SWORDS. And I did teach my people to build buildings, and to work in all manner of wood, and of iron, and of copper, and of brass, AND OF STEEL..."
-- 2 Nephi 5:14-15
Later in the Book of Mormon we read that generations later, the Nephites were still using Scimitar swords
"and his people were armed with swords, and with CIMETERS, and all manner of weapons of war"
-- Alma 43:18, 20, 37, Mosiah 9:16, Alma 60:2, Alma 2:12, Helaman 1:14 & Mosiah 10:8.
Although some BYU "apologists" have tried to explain that this is a mis-translation and was actually an Aztec "macuahuitl", but the fact remains the Joseph Smith chose the word "Cimeter"... So, The Sword of Laban => it has to be;
an actual "sword",
and made of "the most precious steel" or, Wootz steel, known commonly today as "Damascus Steel"
Damascus Steel blades can be recognized by a very unique pattern that comes from the unique forging process, where the metal is pounded out flat, then folded on itself, over and over again [see https://youtu.be/5d1DorsIQRk?t=911]
