1. Uncle Bill, I can send you the piece itself if you want -- I'm not too handy with making stuff. It's still shipping and probably won't arrive for a couple weeks, but when it gets here I'll take better pix and you can decide if you want to copy it.
2. Jeff, I believe they're only sharpened on the convex side; however, some pictures of Kali show her wielding it with the concave edge forward, which would imply that at least some Ram Dao had the inside curve sharpened.
That other sickle-sword from Malabar I posted is like that -- sharp on both sides of the curve but only on the convex length..
3. Blues, that's an impressive looking Panabas. Why don't people give me gifts like that? (Why don't people give me gifts at_all?)
It's funny in a tragic kind of way, but the Panabas, like the Ram Dao in Bengal, is still used to this day to hack people in the Philippines.
