Sinhala / Sri Lankan Swords?

[KuKulzA28]

Hello! I've been curious about Sinhala swords... There doesn't seem to be as much information of Sri Lankan arms on this forum as there is on say Indo-Persian, European, Moro, and others. All I found were a few threads about Piha Kaetta and Kastane.

Does anyone have knowledge and/or sources on Sinhala weaponry especially swords? Anyone actually own examples?

Aside from kastane, the few images I have seen are from the angampora website which shows "urumi"-like flexible blades and also rustic looking sabers/cutlasses with simple guards and wooden cylindrical grips.

I have little to no knowledge of Sinhala swords and other weapons, so I was hoping maybe some EAA Forum members would have knowledge on this matter.

Thanks!
