I am now a proud owner of a 0561, and couldn’t be happier! Upon initial inspection of the knife, however... i noticed a small issue.
The stop pin isn't pressed in to the liner all the way (on the G10 side). The gap is very small, a little smaller than 1/32 of an inch (just eyeballin’).

It doesn’t seem to effect the function of the knife e.g. blade deployment or lock up as of now..

Im just wondering if the knife will wear abnormally over time? or if i’m just overreacting to a small imperfection?
Any input would be greatly appreciated...

The pin is not a stop pin for when it is open, it is a stop pin for when it is closed. The thumb studs act at the blade stops. If you take the knife apart you will see that the stop pin is not pressed in at all, it sits loose.
 
Here is a pic of the pin.

Looks like it just didn't get seated all the way is all. If you loosen the pivot screw (may need to loosen the others a bit also), jiggle the pin and or liners a bit and it should slip in to place all the way, tighten pivot back up.

I agree mine looked like that when I started to put it back together after an itial cleaning. Just had to loosen and reseat.
 
Just an update for you guys, i took apart the knife and the pin wasn’t loose like some of you had said, it was press fit. So i pressed it the rest of the way in very carefully with a vise, everything is perfect now.
 
I just noticed that my 0561 is that way too (but smaller gap).

Mine doesn't bother me, but I've realized that some of you look a lot more closely at your knives than I do - maybe I need to do that more often :)
 
Your washers are too thick. If they were bronze, you could sand them on 1200 grit sandpaper in a swirling motion to remove metal. Not sure how to facilitate the same effect with Nylatron or whatever that knife uses.

On many production knives under the $300 pricepoint, I find I have to break out the caliper and the sandpaper for a precision fit. YMMV.

The 560/561s use a ball bearing system called kvt

That's right, I remember that now. Hmmm, just not sure then how to explain the gap. Unless perhaps it was a funky stop pin. It would be worth checking the gap width at different spots within the interior and see if it flares out significantly in the general area of the pivot and stop pin. Not sure what to make of it when ball bearings impregnated in a washer predetermines the thickness in the pivot area. Curious.
 
I did indeed miss that. Glad that's all the problem was. I've been very impressed with my 0561 but haven't had the op to see what's under the hood for myself.
