Core77

This is a great example of mass production combined with manual production. The knives in this video start off as strips of rolled steel that are cut into blanks, precision-honed by a grinding machine and shaken around in a huge bowl of polishing stones. Then it travels down the assembly line to a bunch of men and women who sharpen, buff, polish and de-burr the knives multiple times; we expected them to have band-aids all over their fingers, but they're consummate pros.

What we've described above are just the production methods used for the blade; the video also covers how the bone handles are made and how the whole kit 'n caboodle goes together at the end. All told, these simple-looking knives go through at least a dozen stages of production.

(Load the video and you can skip the first 22 seconds, which is an idiotic logo screen and techno music lite.)
