Finally got my nihonto back with new tsuka: slightly longer (8sun 5bu), a bit thicker, full black same, navy silk ito, sabi (plain rust) fuchikashira and tadpole (sperm?) menuki. Same old rusty tsuba that I love, but I think I should have changed the seppa (one brass, one silver) to copper, fixed the tsuba (the whole is too big) and gotten a better-fitting habaki...next project!
