Thanks JR, The hanger is fragile and I don't suppose any amount of leather treatment will make any difference.

This was a question I was going to ask, do you keep them on the dagger and risk damage every time you get the dagger out of it's box or do you keep them safe off the dagger?

I have a few WW2 era Japanese swords and all have the knots, hangers and some have surrender tags BUT I keep them separate as these things can easily get damaged.
