Exactly. That was the benefit of mass production... the fact that tolerances were kept within an acceptable range so parts could be interchanged. Prior to that, complex pieces like firearms were produced individually and parts had to be manufactured and fitted individually to repair them. Modern folders fall into the same category, although they're not as complex as old-time firearms. According to knife industry people who should know, CRK has narrowed the range of tolerances in their knives by hand selecting and fitting the parts, and then doing their "fine tuning" to make sure every piece works together to make up the complete package.
