3/4th the weight of an elephant is a whole lot of ants, Tifone... So I think Niefels could do better than balsa wood and wicker weapons. Not to mention that Niefel Giants aren't as big as elephants.

As far as them fighting each other, who's to say they ever did? Unlike the humans and gods in the Norse sagas, the Jotuns themselves were quick to ally with all manner of beings. And I can't recall any specific instances of them fighting amongst themselves. And it was the Norse gods who started things by killing Ymir, the father of *all* Jotuns. It was also the gods who instigated Ragnarok, for that matter, by betraying Fenrir, beheading Mimir, burning Angrboda, and imprisoning and torturing Loki.
