beautiful knives but i ca'nt get over that baby bottom bump.
It's the lock. The stud has flat edges so when it is open the stud's flat edge locks behind that cut out in the top back of the handle. There is a spring above the stud and the stud itself spins. So as you go to unlock it the stud spins and pushes up to release. It's acually a pretty ingenious design and locks the blade into place quite solidly with literally no chance of accidentally releasing the lock while using.
I've never understood what that weird plastic thumbstud mess is all about... what gives?
