Sudan arm dagger restore or not?

[Kmaddock]

Nice enough job
But the fact the glue is wrong colour and the join is jagged it is about the best you were going to get away with.
The only way I would have done any better would be to just make the entire ring section/ un peen the tang and insert a new entire ring and bond to the remainder of the handle but this would have been very very invasive and not something I would willingly do.
Ivory would not match either, have you tried to stain the new ivory with something like tea or coffee, I have never done this myself just wondering can you stain ivory.
