Recent ebay win for comments

[mross]

Won this on ebay from metlman. The picures are his; Thomas Hurst. He allowed me to use them and post here. This is the win that prompted my search that uncovered the Naga database. Any ideas as to age and use? Weapon, tool or both? It's heavy and obviously one handed, the balance is very good. I have to remove the varnish, polish it and etch it. Can anyone translate the script on the scabbard?
