The folding mechanism looks like an inner core that joins two tubes by sliding between them. Am I wrong? Is this design new / unique? I don't recall seeing it on any other folders.

Also, Shimano Zee, while no XTR, is not a cheap group by any stretch.

Still looks interesting, though I'll probably wait until production is confirmed
