a strange hulu detail

[Michel]

Yes Detlef, the piece is glued.
I however doubt the kriss is coming from Ebay as the owner does not utilize Ebay (He is a well known kriss collector with an extensive knowledge on the kriss and the Indonesian culture)
He has not told me where from he got it. He had also not seen such a knob on any kriss.
He unfortunately does not come on the forum as his knowledge would help us a lot but agreed that I ask the question.
May be someone of the forum knows something about this curious knob, tis reason and origin ?
Although a well carved hulu, the gluing is not perfect. To my eyes it is a modern hulu with an added knob. But Why ? What are the reasons that were behind such a strange ad on ?
It cannot be aesthetic, nor functional, what could justify it ?
I am at lost !
Hey, could it be a simple marketing gimmick ? just like the stone or gold piece on the warangka ?
