Found this knife today at a sale and picked it up, handle looks unique and I think it may be bone/ivory, maybe, but i dont really know how to tell. Half of surface seems fairly smooth, with a blue-ish, green-ish, purple-ish tint to it, almost like a mother of pearl shine to it, while the other half looks fairly rigid, almost like the grains are going a different way, so it made a weird pattern towards the one end. Anyway, here are some pictures, its hard to see the shine to the handle in them, but let me know what you think...

side 2
