I can't think of what fantasy novel I got it from, but I have this impression to. Vaguely I remember someone wielding a "cold-iron" sword that had been made from the very material of the heavens (ie, a meteor)

Just because it is called "cold iron" in no way implies that it is the substance we know as Iron, (Fe) on our periodic table, in any game.

No it doesn't but by using the word "Iron" you are asking us to make assumptions about it. If you want it to be something unique, unusual and unrelated to Iron it would be better to give it a different name. By using "Iron" in the name it implies that it is directly related to Iron (Fe) in nature.
Right, it's iron!green slime said:
