Valient Kujang Macan

[jmings]

I just bought a Kujang Macan from Valient America (Bill Wray ) and can't find any information on the net about it.

It's the upper weapon shown below.




Can anyone tell me anything about the knife, its history and usage.
It does look like it would go hand-in-hand with the "Heartless Monkey" style of silat, but I really don't know.

Thanks in advance.
