On a long shot, I emailed the James Knives guys about their knives and the knife designer emailed me back. Totally friendly and open guy, to me.
Tells me that he does the design, the knives are made in China by one of the reputable oems that works for Spyderco and Kershaw, and materials are sourced from all over. He says that the video is dated and that while they used to do the assembly at their shop, the oem does the entire manufacture now.
Whatever else, seems like a legit operation. They're not claiming anything that any other reputable cutler is embarrassed of.
