What a beautiful blade.
This is one of the "standard" styles that you find - concave tip, small 3-part grip, and a button pommel. I used to say with confidence that these are a Kachin-style weapon, but now I have become so uncertain about the geographical/ethnic styles in Burma that it is simply a guess at this point. I miss ~Alaung-phra~'s comments, as they were so well-informed in this regard. Are you out there, Zaw?
