While searching for "Argosax" will either give you the boss from DMC2 or some random internet dweller using the name, breaking it in parts gives some interesting results.
Argo is considered a feminine name. It was the name of the ship Jason and his crew used (hence Argonauts), based on the name of it's builder Argus (not to be confused with the 100-eyed giant).
Argo was also the name of Xena's horse, if you are interested.
The name Argus came from Greek word argos, meaning glistening or shining, though some also connect name Argo to word argyros - silver.
Sax has no results, search only gives me Saxa and Saxon, both came from Germanic word sahs, meaning knife.
What would that have anything to do with Argosax we know, your guess is as good as mine. *sips coffee*
