That would be interesting to know. No country on the blade, but the box also says "Taiwan" sans any specifics. I've looked on the 'net, but either my Google Fu is lacking or there is no mention of the specific factory.
We know that when the Ripple was initially made in Taiwan, the prototypes (and initial run) did not meet Ken Onion's standards and he made a personal trip to whatever factory made that knife and initiated corrections and a philosophy change. IIRC, he spent 6 weeks bringing that group up to speed which is why we now see a very decent Ripple available to the public. Since the Ripple production, all of the collaborative pieces that I own have had a much higher standard of F&F (IMHO).
I would guess, and it is only speculation, that it is not the Taichung factory that produces Sypderco else the Ripple would have had high standards to begin with. Perhaps it is instead a different facility (or facilities, plural) that have been brought up to higher standards. I am sitting here with a CRKT Klecker Graphite in my hands and it has an outstanding F&F. My piece has absolutely no flaws, flips beautifully, with a perfectly centered blade. It seems equal to, or better than, anything that Kershaw produces (at least the 40 or so pieces that I own). This has been true of almost every (newly designed) CRKT knife that I have bought since the Ripple. The Eros, Fossil, Sampas, Nirk Tighe, Graphite, and Carajas are all very well made knives lacking only better steel for the blade. But the manufacturing is spot-on.
I'm only guessing, but it seems to me that the quality of their knives went up significantly after the Onion/Taiwan fiasco and it is hard for me to conceive that to be mere coincidence.
That said, I really know nothing about the actual process or where - specifically - they are made. Just guessin'.
JMO.
