As someone who is not particularly mechanically inclined (I download Bob Terzuola's book and my brain exploded after a few pages), can someone explain how exactly it is that "lock flex" works? I'm specifically speaking about when you apply negative force to the blade on a liner or frame lock folder, and you can feel the lock being pushed down, almost like a small amount of lock rock. Usually lock flex will result in lock slippage if the lockface isn't clean, however the knives I have that seem to flex do not have issues with lock slip.
What confuses me is that originally I assumed it was the thickness/tension of the lockbar, but testing this on different knives yields different results. My Emerson's, for example, can all be flexed despite having relatively thick liners with no milled out portion. Is it a result of the amount of lockbar in contact with the lockface? Because I have had very thin liners that didn't flex (which appear to have less contact area than thicker liners). Furthermore, is there anyway to remedy this or is it simply a function of some mechanical forces beyond my comprehension?
Thanks for helping a brother out!
