We are getting there slowely.

I have some better pictures of the hilt from different angles.
Please note the very small notch on the top, that seems to be worn of in time.

I received pictures from a forumite of spermwhale tooth objects that were discoloured towards brown/brownish (thanks!). Looks a bit like this hilt. But this hilt has several pieces that almost look like wood on the top and left side. Nothing I have ever seen before.
