This is very informative, thx. I wonder if you can share your experience of eliminating lock stickiness of Spyderco Military, specifically the kw exclusive s90v ti/cf model. It is not severe but it is thete. When I disassembled the onife, I only removed the screws on the lock side and slided the two scales away pivoted at the lanyard tube. Its now centered no play and free droping, but just somewhat sticky.
