How to secure a loose tang pin on a balisong?

[Colog]

I have a balisong with a loose tang pin. I sent it back to the maker, but it fell out almost immedialty after getting it back. Very annoyed since I paid over a grand for this thing. So my question is, is there anything I can do to secure this thing myself? Perhaps the strongest loctite would work. I don't know. What do you all suggest? Don't ask who the maker is, I won't say publicly.
