I've been a member of the forum long enough to have seen the depth of the discussions, but the archived threads never cease to astonish and delight me. Thank you Josh for the link! From there I was able to find quite a bit of useful information! There is little doubt in my mind that these are Bao An knives. For the record, here is a short description given by another member of this ethnic group:

"The formal name of Bao An people is Bonan ethnic minority group, whose home is mainly at the foot of JiShi mountain, almost at the boundary of GanSu and QingHai province . The population of Bonan ethnic minority group is about 16,505. Their local language belong to Mongolian Austronesian. Their religion is Islam. In China, Bonan ethnic minority group is famous for their man-made knives-Bonan Dao."
