This one also requires that you sacrifice the appearance of the Gamorrean War Axe, and will overwrite the double-bladed axe I posted previously.

Edit: Added a .uti file to the .zip that increases the damage, gives bonus feats to user. I also gave it a little transparency. I had a 4-blade version, but it looked like a christmas tree, so I scrapped it.
Put everything in Override.

Note: The icon in the weapons-equipping screen still looks like a Gamorrean axe. This one will say "Green Battleaxe".
Strangely enough, the Gamorreans keep their old axe designs. They must be part of the Gammorean model.
