Pamor Blade of a Pedang Lurus

[CharlesS]

I would like to learn more about the blade of this pedang lurus. I have no idea of the age. It looks old to me, but some of the blade makers in Indonesia today are doing some very good work.

The dress is silver alloy, not particularly of good quality and doesn't show much age.

BUT!...it is the BLADE I am interested in. Whether old or more recent, I am fascinated by the construction of this blade and have seen nothing like it before.

I hope I can learn more about the pamor and its purpose here. Perhaps I can also get some clue about the age of the blade. It may very well be that it was not "born with" the rest.

Thanks for any input.
