As posted the ceramic ball has two functions, one to keep the blade in the closed position like any other framelock and the other as the lock face that moves behind the blade when open to keep it open. When it came out some questioned if the ceramic ball that doubled as the frame lock contact with the blade was durable enough.
Chris Reeve showed him pounding it on an anvil and it dented the anvil, so it can take a considerable amount of impact.
Normal framelocks you have the detent and normal Ti lock face that is heat treated to near ceramic hardness that contacts with the blade to keep the blade open. The Umnumzaan opens and locks on the ceramic ball two birds with one stone. I have a bunch of pictures I could show, but the computer is screwed and I am on the phone, sorry.
Does this make any sense?
I have a detailed post I do based on my talking to makers, reading and talking to engineers about liner and frame locks geometry. I will post it here for you in the folder thread when I can.
