Duck, something about that screams to me its for some sort of casting. Just out of curiousity, is there any holes on the inside opposite the center square channel? If so I think it's upside down, that would be a pouring ramp, the two holes on either side would be sprue holes for excess material pouring out. If so, I'd recommend trading/selling it off as apposed to using it for a forging shape. As it would probably be more appreciated in the hands of an amateur caster for the purpose it was intended for.
