So I am now the proud owner of two bearing knives (zt0452 & civivi aquila), both of which I have seen many others online achieve a drop-shut action with either literally just gravity, or at most, the lightest wrist effort you could imagine. My question is... what the HELL do I have to do to get this kind of action? I have tried disassembling & reassembling. I have tried tons of lube. Minimal lube. No lube. Light weight oil. Moderate weight grease. The only way I can come close to a drop-shut action is by loosening the pivot to the point where I have blade play and the centering is horrible. Yet the ones I see online have this insane drop shut action with perfect centering. Nick shabazz has a video where he works on the zt0452. He gets it pretty damn nice without blade play. Mine doesn't come nearly close to that. Anyone have good experience here? I'm desperate enough to drop some cash on nano oil. I've heard some people say using a really heavy weight oil on the detent track helps a lot.
