Just found a gem of a video about the Shi-Lin Dao that Bob based his Chinese Folder design on. The video is in a mixture of Taiwanese and Mandarin Chinese with Japanese subtitles, but it shows the store where the Shi-Lin Dao is made, in the small cutlery shop based in Taipei Taiwan. The design is over 100 years old, and can be found in many sizes.
And a second video on the history of the store:
Unfortunately, the store is currently closed, pending reorganization: http://shilin-cutter.com.tw
