Thats an .09 fused item. Allow me to explain.
During excessive lagging on the servers these items would sometimes drop. Normally, Hephasto would've dropped the gnasher(unique hand axe) and a hellforge hammer. During these excessive lags, about 1% of the time the game would "forget" to drop the second item, when id'd it would have the stats of the other that was supposed to drop. This is how Wiz rings, ck ammy, soulflay gaunts were created.

It's very hard to explain, so I'm sorry if this explanation is a bit weird, but that is how that item was created.
