I'm trying to refinish an old dresser, but ran into a stumbling block
when trying to take the hardware off the drawers. The knobs and
handles are not screwed on, but from the inside have some form of
connection I have not seen before. Can anyone tell me what this type
of mechanism is called and how I can remove it without destroying the
drawer front? Image is he

The picture doesn't show it great, but the inside of the piece is
hollow and threaded. What for, I can't say...

Thanks.
