Whatzit ??

I'd call it a good deal.

This has an interesting combination of elements, and I'm not certain whether we're looking at something put together from pieces later in its life, or an original weapon.

The blade is a nice example of a Kachin (Jingpaw) dha. I think the other dha guys would agree this particular type with the slightly flared, straight blade may be a transitional form between the Naga dao and curved Kachin square-tipped dha blades.

The open sided scabbard reminds me of Naga dao scabbards, but I have seen some similar Kachin work.

The tiger jaw section is also something seen with Kachin weapons.

The guard looks Chinese to me, and is unusual on swords like this.

There are other interesting elements to this thing, but I'm short on time. Cool sword!
