Large Bali or Lombok keris for comment

[kai]

Interesting little depression on the handle; for the thumb perhaps?

I don't think so, Rick: While the edges are worn smooth, the surface of that depression is not really smooth. Thus, this looks like an damage to me that happened during the active life of this keris.

Having said this, I'd estimate the fittings to be from the 20th century; the crosspiece might be a tad older than the rest.
