Raider axe

The raider axe is an item that is obtained by talking to Hollowtoof, leader of the goblin raids (with sufficiently high combat levels, around level 90) or by killing him after all the other goblins in the raid are killed. It has stats roughly comparable to an iron battleaxe; while the damage output is the same, the raider axe provides a lower accuracy rating than its iron counterpart does. To wield this you need an Attack level of 8.

Hollowtoof appears to be wielding this axe, along with the Goblin Raider.
