Whatzit ??

[Mark]

I found a photo on hand of my "Naga" dao with the jaw bone (its the top sword in the photo). Unfortunately, the jaw is barely visible behind the shoulder strap. The dao out of its scabbard is about 20"/50cm long, and the piece of jaw is about 3"/7cm long, so the jaw proportionally looks to be roughly the same size as that on our subject sword.

I'll post a close-up of the jaw tonight.
