UPDATE: I tightened the pivot screw a micro turn and the blade dropped right into dead center position and the funny result was my action feels even smoother than before which already was pretty good. I've yet to visually or cogently analyze why but it was noticeable to me. Also, the pivot was already very tight. It took all my strength to tighten it down that extra micro turn without heating the screw and/or stripping it but I did it. I barely felt the nudge when it turned.
Does anyone know if this is a bushing? I thought not.
Although the OOTB sharpness was never a gripe, I also ran the edge over my AG Russell Ceramic Sharpener a few times then stropped it with my KnivesPlus loaded strop and this knife pops hairs before the edge even touches the hair now

I can also comment that the Spyderco heat treated CPM M4 steel feels VERY hard. There was literally no feeling of bite on the ceramic rods. But they did the trick even if it felt like I was stroking the edge on glass. It must have only been a wire edge. The edge grind is really thin and even so this knife is a major slicer now!
Regardless, one of three minor gripes is gone. Of course I can live with that super faint horizontal scratch on the blade and the minor grind burn.
Success!
