Hi,
it's ivory, for sure. Wotan is right with his recommendation not to disassemble daggers. In the beginning I tried to open every dagger, of course not by unsing any force. Vic explained me several times that for a trained eye it is not necessary to do that and he is right with this. However I am still curious to see what is stamped to the tang ... :-)
