Indian Sacrificial? Sword

[naborow]

I think this substantial sword is called a Tegha. through lots of internet looking i found a similar one that said it was used to sacrifice buffaloes during the festival of Dussehra. The sword on the internet said it was Rajput. It is full of interesting figures. The main figure (in brass or gold?) looks like Krishna (with a flute?) Some of the other figures carry a trident, mace and lotus, and other Hindu god identifiers. But one image has what looks like angel wings? There is script (i think) on the top wide part of the blade which is not recognizable to me.
Any Information on age, use, location, maintenance would be most helpful
