Keris or not?

[A. G. Maisey]

That "Origin" paper is pretty old, the core of it, I think I can still support, but it really needs to be rechurned.

Hugh, the simple answer to your question is that I do not know why most keris are asymmetrical. We can hypothesise, but perhaps that's the best we can do. I think its probably a "form follows function" thing, given the original form of the archaic keris, & the way it was used. But we really have no certainty.
