Two dao from Arunachal Pradesh

[Sajen]

The first dao is cleaned up, the scabbard will need some time more. Both dao have some age, I would guess first half of 20th century, the patina at the handles and scabbards let me think like this. Special the bone pieces at the handles show a nice smooth patination.
The blade of the cleaned dao is well worked and show after a mild etch with vinegar a hamon, not continous visible since I don't have polished the blade but good visible at the tip of the blade and in the back (you are proven wrong spiral ) . The blade has also a maker mark in front.
Here some pictures.
