Indian Swords with downward curving blades

[blue lander]

The auction for this one recently ended, nobody bid on it. It was described as a "Ayda Katti" from the Malabar Coast. I *think* the blade is downward curving? It's hard to tell which edge is sharpened. From the orientation of the hilt I'd imagine it'd be hard to wield if it was upward curving.
