I just tried to give my Inkosi a good flex. I took it apart when I first got it to remove the lanyard without untying it. I gave it a good cleaning, a greasing, and put it back together. Maybe just a teeny bit looser than it was.
With two hands, and careful fingers, I could get the blade to wiggle what I could only describe as maybe 1/64 of an inch. That took a full bit of effort on my part and would have never been noticed when under heavy use. I decided to see if this was as good as I could get it. A quick crank of the allen wrenches and the Inkosi was rock solid if a bit too tight to open easily. Backing the pivot screw off no more than a hint of a counterclockwise movement resulted in a knife that will easily open with a thumb (not turning it into a flicking knife) like glass and is so rock solid open I managed to give myself a little love bite with the edge and no play at all.
Long story short, even a CRK with built in adjustment should have no blade play unless looser tolerances for faster deployment at the expense of fit is ok with you.
I rather like the bank vault lock up. I didnt buy the knife to be fast. I bought it because it's perfect. Silky and patient and everything I could want to fidget open and closed on the couch. The gentle break of the detent. The audible snap of the lock up. The rugged and rigid fit. The tiny snapping like a glass rod breaking when the detent engages the knife closed.
Blade play, short of trying so hard you cut yourself, shouldn't be possible with a CRK.
