Just ordered a Para2 so I can sample the US made models, but so far, my Taiwan models have not disappointed. My Sage 1 was flawless and the action was like an oiled ball-bearing on glass. Same with the Gayle Bradley.
My Caly3 (Japan-made) was not like that at all. I understand that it was a different design being a lock-back and it had no bushings to maintain its thin profile, but still - it was very rough when I got it and after working it for a while, I took it apart, cleaned it and lubed with quality lube and it was much better, but still not quite like the liner-lock Sage 1 (again, noting that the difference in design comes into play here).
So far, my Perrin PPT (another Taiwan made model) is pretty much flawless other than one tiny little spot by the relief cut on the outside of the lock-bar. It's just a tiny rough spot on the outside edge of the lock-bar, and it took me a while to even notice it, but it looks like a tooling mark. Other than that tiny mark, its been perfect. The action isn't as nice as that of my Sage1 (which might be in part due to the lock-bar putting more stress on the ball-detent than the liner of the Sage did), but its much better than the Caly3's was.
I'm no country-of-origin hater though

I plan on getting another Japan-made model soon enough and depending on how this Para2 goes, probably another US-made one after that.
You know... I got into knives because they were supposedly cheaper than guns. So far, I've not found that to be the case
