Sulawesi (toraja?) keris

[David]

So i've moved on to youtube ( ) in search of the Torajan keris and we do in fact see it as part of the present day "traditional" wedding. Again it is interesting to see girls and boys in traditional dress with keris.

You can also see women in a traditional dance with "keris" in their waist bands. I suspect from the look of these that these are not real keris, but merely props. Were they always a part of this traditional dance?

At about 8:16 into this video on a Torajan funeral they do show a couple of men in traditional dress holding keris and then also in procession.

However here is another, perhaps older, video of a funeral where i see no keris present throughout the ceremony.

I would have expected to see some keris in the waistbands of the men singing at the end of the video at least.
I am curious about what this all means in terms of how and when the keris may have been assimilated into the Torajan culture and what it means for them as opposes to, say a Javanese or Balinese man.
