A big difference of course is: growing up in a culture where the dagger is a part of cultural heritage, or someone who is interested and becomes a keris-collector on the other side of the world.
And in my opinion the language is the biggest problem, when I look for information, I first look in books written in my own language.
Like my believe that this is pamor Tejo-Kinurung.
I've looked in the book "The kris part 2” of Tammens page:138-139
( I know that these books are not always give the right information)
But this is what Tammens wrote:
Tejo Kinurung: “Three times lightning”
Not a general pamor motif, but certainly quite impressive.
At first glance it resembles a kekumus in a wengkon, but this is not
correct. The empu deliberately placed both outer lines more towards
the middle, so it cannot possibly be classified as wengkon.
So that was my guide to come to the conclusion that it was:
pamor Tejo-Kinurung. And therefore a comment given by someone with a different perspective on things is so appreciated. (not only by me!)
So thank you all for doing this..
and I'm now convinced that it is indeed pamor: Adeg-Tiga
