Leatherman: how to fix

[cema]

The corkscrew in my Leatherman Flair multitool broke. The screw itself broke apart (and was thrown away).

I want to keep the tool but replace the corkscrew. Any hints as to how to better have it done? I would need a replacement corkscrew, a way to remove the small piece of the old one still attached to the tool, and then reattach the new one.

Thanks in advance.
