I previously posted this earlier in the thread. I just fixed mine. After a lot of inspections I realized that if I pushed the lockbar down, just that slight more pressure held the blade in solid. But it wasn’t spring tension, because of what I discovered. The lockbar was being stopped by the larger pin to early when closed. The pin the blade stops on when open. I took a fine diamond stone and started to file the face of the lockbar, the part the contacts the triad lock pin. I kept checking fitment. Finally the lockbar fell on its own with spring tension to where the blade play stopped in the closed position. Locks up solid when open. Locks solid when closed. I hope that all made sense.
