A few have mentioned with disdain that after re-assembly their blade wasn't centered. Even on a YouTube a complaint that the knife wasn't precision enough, because it didn't re-center after re-assembly.
The blade tip being centered as many know is simply an assembly procedure of getting it centered. It'd the assemblers job, and not difficult. When doing an assembly do not tighten any screws until they are all in and check for tip center, flex handle to center and snug a few screws, check again, re-do, once centered snug the screws, don't over tighten, when they stop firmly that's it. The pivot screw should also be snugged and backed off a quarter to a half turn. The blade pivot will always feel tighter at first and settle to smoother and easier, after a few dozen openings.
