"The lock works similar in principal to a lockback. The difference is the lock is contained inside the pivot hole of the blade. The lock is therefore sealed from outside debris, and leaves the rest of the knife free of other working parts like springs and lockbars. The lock is disenguaged by pushing up on the tab at the bottom of the blade tang, then rotate closed. When opening the blade, it will stand high of the frame at the spine until it is 99% open, then falls into the lock faces. The forward face of the spine is the rear lock face, the forward lock face is on a boss on the pivot bushing. A coil spring and bearing inserted into the edge of the pivot provided the downward force that keeps the lock enguaged. The blade is only.001" thinner than the pivot bushing, so any debris has to be thinner than a human hair to get in. I have dropped my work knife in the fine sand we have here in East Texas, and the lock stayed completely free and clean. From all of my tests, the lock is just as strong as a lockback. "
