Hi Ben,
Yes, I agree that my parang does not follow the mandau classification strictly.
Maybe better to call it a Dayak parang inspired by the Malay swords like yours?
Both the blades you show are very interesting variations. The heavy Jimpul with Latok resembling handle is unique as far as I know.
On the 1820 Dayak sword you showed me I think it's a Parang Pedang.
