Found this axe on eBay......probably not functional... as to the inherant weaknesses with 'forked' branches. Carving on the prongs seems to indicate either male/female or two differing status symbols (head piece/hat?).
Any ideas as to Tribe or function???..... I'm guessing that is not a sort of Swiss Army knife.........with an axe/catapult combo....
