Jarnsaxa is Norse in Origin.

Jarnsaxa is a mythic feminine name from Old Norse Járnsaxa, built from járn “iron” and sax(a) “short sword, dagger,” yielding senses like “iron-knife,” “iron blade,” or “she who wields the iron blade.” It belongs to the vocabulary of warfare and cutting implements shared across Germanic languages (cf. Old English seax).

In Norse literature Járnsaxa is a jötunn/giantess: Snorri names her as Thor’s consort and mother of Magni; some poems also list her among Heimdallr’s nine mothers, showing the fluidity of mythic tradition. As a personal name it is virtually unattested historically and remains extremely rare today, though it appears in modern fantasy and in astronomy as the Saturnian moon Jarnsaxa. Variants include Járnsaxa (Old Norse/Icelandic), Jarnsaxa (anglicized), and Järnsaxa (Swedish orthography). Short form Saxa occasionally serves as a wearable nickname or spin-off.
