My first moro kris

[ThePepperSkull]

Wanted to up this thread in particular because of the weaving done on the Scabbard. Like Ian, I wonder if this could be a Yakan piece -- at least in terms of the weaving on the scabbard, but that brings me to a question:

I am aware that the Yakans preferred the Pira over other blades, and that there are several examples of Yakan-made Barung (I assume due to the expansion of the Sulu Sultanate and the settling of the Bajau people in Basilan).... But were the Yakan ever known to use Kris? It had just occured to me that I have not seen a Yakan Kris nor do I know if they exist. (potentially aside from this piece, but it could very well just be a re-binding of a kris from elsewhere like Sulu)

If they do exist, would this piece be an example of a Yakan Kris? If not, what features would they have to typify them as originating from Yakan in terms of manufacture? And if they did not exist at all aside from recycling Sulu kris, why did the Kris not catch on in Basilan amonst the Yakans like the Barung did?
