I've had CRKs with that infamous "bank vault" lock up. If I fidget with them long enough I can make my thumb sore from the constant unlocking of the tight lockup.
More recently I got a Shirogorov flipper and it is a whole different animal. The metal bits are a bit more thin and elegant. The result is my lock bar moves with pressure more easily. This was initially problematic on my NeOn Zero as the slightest touch to the lock bar while opening would prevent its opening. I've since trained my hand to not touch the lock bar when opening. With that said, the lock up always seemed secure. But more recently I noticed if I open my knife and still hold it without touching the lock bar there is actually a micro-meter or two of play in the blade. But the way the knife is designed, once you open it you either want to immediately close it (because it is a fidget) or you want to use it and your hand wraps around the scales. When doing the latter, the lock up immediately becomes firm resulting in no blade play because the slightest pressure on the lock bar immediately closes that 1 or 2 micrometer gap.
Upon this discovery my initial reaction was thinking I might want to bend in the lock bar by the slightest amount to tighten things up. But as I thought about it, I realized as much as I fidget with this knife, likely opening and closing it a few hundred times between each cut, those micrometers of space 1) likely reduce wear to lock bar insert/blade tang when I fidget 2) make the opening of the lock bar easier when I fidget.
Like I said, the really insignificant blade looseness took a month to even reveal itself to me, because every other time I would check the blade I would have a proper knife grip, not like I'm drinking tea in England. With any type of normal knife grip on this knife some part of the hand is touching the lock bar and the issue becomes moot. Anybody live with or prefer this situation, or would OCD drive you nuts and then you would feel compelled to "correct"?
