When I first got into the knife game in a serious way back in about 2007, I didn't understand what fit and finish meant. It wasn't even in my vocabulary. I figured that if everything was the right size and fit together, I can't see how it could 'fit' together any better. "Finish" I could understand a bit better, but even still it could only have a nice smooth metal finish, what more could it be?
Actually I think I didn't really understand for quite some time until I did get my first CRK a year or two later. That was my introduction into true close machining tolerances and truly even finishes. The way that you'll truly appreciate a CRK is by realizing that it goes back together the same everytime you take it apart and put it back together (it should), and by looking very close at all the chamfers around the edges of the scales and seeing that they're all perfectly even, and by looking very close at the bead/glass blasting and seeing that they didn't leave any CNC machining lines behind (these last 2 are extremely rare, and in fact I haven't seen it on any other knife, production or custom, except for maybe 1 or 2 other examples, and I really check for these kinds of things), and by realizing that you can clean the whole knife just by taking out the pivot and the blade and washers come out with the rest of the handle still assembled.
It's really all in the fine details like a finely made watch (I don't have any really expensive finely made watches that watch aficionados would say have truly great fit and finish). So at the end of the day you just have to decide if that's something that brings you joy. Even chamfers and smooth finishes (without machining lines showing underneath) are exceeding rare though, you're not going to see that on the edges of your scales on any of your Spydercos, Benchmades, Emersons, etc.
