Nice catch Ben!
I find the carved rib over the Tumpal (Tree of life) motif on the handle very unusual. Have you seen it before?
On the crowit and point I am not sure what you mean?
Maybe you could post some close ups of those parts of the blade and explain?
It's hard to see on the, quite dark, overall picture of the blade.
Don't you think the silver work resemble motifs found on Melanau hilts?
Bill, I think that the leech and taste of blood story is something made up outside Borneo.
But of course I might be wrong?
Like the story about the brass dots representing amount of taken heads etc.
