Almost certainly ebony. Early stainless, as you know. And not checked/cracked like ebony is prone to do. Nice one.
I can't get photos of them, but have a couple that I had my 45-year-old African blackwood put on...I selected sticks with no contrasting color...when I got them back, I thought I might as well have had Micarta put on them!

Most likely, but I have seen Braz rosewood dark like that, and friggin hard.
I am gonna go "out on a limb" and say Rocky's handle is the same material, whatever it is.
