Excellent post, Brian. Thank you.
Rob, a great wealth of information resides in this forum and its archives. The membership here has a broad base of experience from collecting to research.
However, the study of ethnographic weaponry is often a rather esoteric and exotic pursuit. Poor documentation, extravagent and incredible provenance, colonialistic perspective and language barriers all contribute to the unanswered questions. It was this very lack of reliable information that first attracted me to ethnographic weapons and continues to keep me engaged and intellectually stimulated. While such things as militaria and
nihonto have always fascinated me, there are few "mysteries" left to explore in those areas.
These forums are often a good starting place for research and investigation, as well as a place to share knowlege, experience and speculation. I once described the process as "edged weapon free-association" (or something similar). I truly hope you'll stick around and share more with us, despite your obvious disappointment. You may yet find the answers to your questions, or even to questions you've not yet thought of.
Best,
Andrew
