China doesn't have the same quality control standards as pretty much every other country on earth. Doesn't matter if it's Kershaw's china plant, or Spyderco's, or Kizer's, or no-name chinese brands, the quality variations from knife to knife are appalling sometimes. Example, I have a tenacious that is pretty close to perfect, as far as a tenacious can go, and then I have one that will not center no matter what you do, opened it up and the washers weren't stamped out correctly, they had jagged edges and pieces of the stamping inside of the pivot making it very rough, and so forth. I've had the same kershaw model with extremely different edge grinds and actions, and I bought 2 of the same Kizer knife at once, again with highly varying quality. Flashy designs that have built in acceptance for loose tolerances is what China is known for.
