Hanwei QuanDong Folder: how to disassemble?

[bigbore.45]

Any idea how to take apart a Hanwei QuanDong Folder?
I want to do some change to the button lock.

I don't think it's meant to be disassembled. You will need to pry the bolster off the horn grip to get at the release button, but you'll probably bend bolster & scratch the horn.
