Thanks to both Brian and kissakai. I’m 95% confident that it is ivory as I imported it from England and had to jump through hoops to get it to the states.
i never held out that the blade was anything more then for the export market. I was interested in trying to remove the tsuka to check the tang but I believe it is not meant to be removed. No mekugi except in the very bottom that is set vertically not perpendicular. Any ideas
