I think it likely that some play has been placed in the production of the pommel at #1 here at thread...
… It could be a walking stick head reformed onto this hilt for example and I suspect the ring of bone half way up the grip is also added.
As others have said this doesn't mean the whole thing is fiddled with as there may be a good blade here...I place a highly ornate elephant hilted tulvar and a contemporary dagger and an elephant walking stick head...
