Hook Sword or Axe ID Help Please

[Tim Simmons]

I am not sure this is Asian work. These picture show hook very similar indeed. They are usually a heavy blade with a strong back. I have not seen one with a chased back but that still does not say Asian to me. I have not seen one with brass at the forte either, I have seen brass decoration on the handle. The brass on the forte here again does not make me think of Asia. I can see the horn as original to the blade and the way the blade was set in the horn with some sort of adhisive substance does make me think of Africa.
