For those who are fascinated with the relationships between geograpically-dispersed tribal groups, it is interesting to note the scabbard on this knife, with its open front secured by a series of parallel bands or thin bars. Variations on this scabbard concept are found in the Northern Philippines (the Ifugao are one tribe that comes to mind), among the Kachins of northern Burma, and even in the lowlands of Bhutan.
Some years ago, I teamed up with a colleague, the late Sherrod V. Anderson MD, to write an intro essay on Taiwan aboriginal swords. I believe it's still up on
www.sevenstarstrading.com . The article does touch upon the relationships between Taiwan's native highlanders with tribes in the rest of SE Asia.
