I'm not sure why members are always sheepish about resurrecting old threads. If there is new information that os pertinent to the discussion it seems to me exactly what you should do. So i would say it does indeed make more sense to add to this thread rather than begin another.
I'm not sure how much new info this particular article has added. I already posted the bit about the iron dagger gift to KT's grandfather Amenhotep III, suggesting it might in fact be the same dagger.
The article does talk about Widmanstätten pattern made visible through X-ray and points out that this means the blade was forged at temperatures lower than general steel forging points. The photos in the article don't show that very well, but there are some better photos in this article linked below. If indeed these are Widmanstätten patterns that does indeed seem to point to meteoric origin.
