Any info on this kind of Sumatran knife?

[KuKulzA28]

Hmm... this is very interesting. This knife must have a very small handle right? I mean if the blade is 7.5", then the grip of the handle is probably only 1.5" to 2" right? Or is there a different grip technique?

Could the origin be discovered with the sheath style and the pommel style? I hesitate to use that since there's a lot of common hilt styles in Indonesia, for example my favorites - the makara pommel-ed pedangs and klewangs that are attributed to east Sumtra and Lombok... this one looks similar

Thanks for the added info kai and Rick.

Is "piso" the same as "pisau"?

and on a side note... "piso podang" - is the piso the same piso as kai referred to (knife)? And is "podang" simply another spelling of pedang? Iknow it might be common knowledge for Indonesian traditional weapon gurus, but I just wanted to clarify that for myself..

Thanks!
