An ambidextrous AFCK is truly the way to go, IMHO. And it'd be so easy... Just a set of holes on the opposite side, and the clip could be moved at will. This simple modification would benefit not only southpaws, but also those who carry a folder as a back-up to another tool, accessible to their other hand - and then, there are those (like myself) who carry two knives...
All in all, seems like a worthy idea.
