Lax16,
It is fairly silly to think that I “have them memorized”. (I don’t–it’s not a big deal to me, at all. But I can certainly use a search tool given that
lds.org has that available for all the LDS scriptures.)
Search results for “sword of steel”:
1 Ne. 4: 9
9 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.
Ether 7: 9
9 Wherefore, he came to the hill Ephraim, and he did molten out of the hill, and made swords out of steel for those whom he had drawn away with him; and after he had armed them with swords he returned to the city Nehor, and gave battle unto his brother Corihor, by which means he obtained the kingdom and restored it unto his father Kib.
Search results for “breastplate of brass”:
Mosiah 8: 10
10 And behold, also, they have brought breastplates, which are large, and they are of brass and of copper, and are perfectly sound.
The passage in 1 Nephi is talking about the “sword of Laban” which was brought by Nephi from Jerusalem, and was kept as a sort of “artifact” and actually was used as an example of how to configure a sword in its shape, but in no other place does there appear in the Book of Mormon language that suggests that swords were made of steel by either the Nephites or the Lamanites, and note also that the Lamanites are said to have swords several times yet only Nephi is discussed as having brought with him the skill and knowledge of how to do metal work within the Nephite and Lamanite time frame, and taught that knowledge to his followers but not to the Lamanites since they had left as enemies and became nomadic.
The passage in Ether is talking about the Jaredites, who were an earlier group in the New World and died out around 588 BC.
Those are the only references to “sword of steel”, and the Jaredite reference occurred in about 2000 BC. So it is not a logical assumption to assume that every use of the word “sword” in the Book of Mormon is talking about a metal sword, and quite the contrary since the Lamanites are said to have swords and they had no such knowledge base among them.
The Nephites had “breastplates”, but no reference is made that those breastplates were made of metal. The Jaredite group had “breastplates” and some of those were made of “brass and copper” which stood out as something unusual enough to point out by the Mulekites who found the artifacts.
So, again, there is not the slightest indication that the battles around Cumorah used metal weapons or metal breastplates.
As far as cement dwellings, here are the search results for “cement”:
Hel. 3:3 And it came to pass in the *forty and sixth, yea, there was much contention and many dissensions; in the which there were an exceedingly great many who departed out of the land of Zarahemla, and went forth unto the land northward to inherit the land.
4 And they did travel to an exceedingly great distance, insomuch that they came to large bodies of water and many rivers.
5 Yea, and even they did spread forth into all parts of the land, into whatever parts it had not been rendered desolate and without timber, because of the many inhabitants who had before inherited the land.
6 And now no part of the land was desolate, save it were for timber; but because of the greatness of the destruction of the people who had before inhabited the land it was called desolate.
7 And there being but little timber upon the face of the land, nevertheless the people who went forth became exceedingly expert in the working of cement; therefore they did build houses of cement, in the which they did dwell.

9 And the people who were in the land northward did dwell in tents, and in houses of cement, and they did suffer whatsoever tree should spring up upon the face of the land that it should grow up, that in time they might have timber to build their houses, yea, their cities, and their temples, and their synagogues, and their sanctuaries, and all manner of their buildings.

11 And thus they did enable the people in the land northward that they might build many cities, both of wood and of cement.
So wood was the preferred building material, and cement was used if wood was not available, but in certain locations only which are described as being built at places “exceedingly great distance” “northward”. This could be near the Great Lakes, or who knows where.
