Javanese machete??

[tunggulametung]

Henk, I'm not sure about the correct name but I'm guessing an evolution of kudi (which is no longer a popular tool), the shape is somewhat (more popular) bendo-heavy chopping utility knife and arit/clurit-sickle combo in Java at present time. Both I mention later has variations and local names and this might fall in one or another. I attached some internet photo for reference.
