Repairing a faulty saya

[Todashi]

I had a saya made in Japan many years ago, and subsequently, part of it has come loose. It's in handachi/tachi style, and is otherwise perfect, but there is a metal collar (apologies, I can't remember the proper term for it) that is meant to be stuck to the saya approximately six inches up from the end.

 

But it's come loose and is sliding freely up and down. I suspect that the saya is actually a tiny bit too thin for it, but it was stuck on when I first got it. 

Anyone got any suggestions on how best to repair this? What's the best way to bond metal to lacquered wood. Is something like superglue the way to go, or is there a better way to do this, short of sending the saya back to Japan.

Depending on the lacquer that was used for the SAYA, high-viscosity super glue could work. It looks as if the SEMEGANE was fixed with glue which is not the traditional way I think, but you will probably not know what kind of glue had been used.  

If it were mine, I would fix it permanently with 'two component adhesive' (Araldite adhesive). Another possibility would be a tiny piece of (folded?) paper jammed under the SEMEGANE.

Japanese news paper soaks up saya moisture and oil very well.  I can't count how many people have found and scratched there heads,

Thanks for the replies. I've used an epoxy putty to do a repair, as it *should* improve the fit a little of the semegane. We'll see how it sets. Curing up now.
