James,
No, I did not know that they are used to hurt or even kill enemies. I should have been clearer on that. The sword itself is like, as I mentioned, an overgrown machete. My first thought was that it should make a nice machete, and this was further confirmed by the fact that the guides used them for whacking bushes. As for collecting heads for some sort of trophies, yes I found out LATER that it is so. Should I know that earlier, I wouldn't even buy it. When my guide told me about a 'spirit' inside the blade (he told me in a very general way, nothing about killing was mentioned
), I laughed. You have to understand that that part of the country is very primitive, and still untouched by civilization. For me such stories, by such people, ARE hard to believe.
I think it is important to note that Indonesia has more than 130 different ethnics, and I was familiar with a few, but not Dayaks. The decapitation of enemies is not common among the other ethnics, only Dayaks, and no it's not normal in any other part of the country. I chased this information long after the experience.
I have quite a few pieces from other parts of Indonesia: krisses, gulogs, parangs, kerambits, rencongs, and some that I could not even name, in general they are more menacing-looking than the mandaus. The interesting part is that the mandaus look plain and very basic, yet used in gorier situations.
About how I got the visions, I don't have a single clue. I'd be happy to reconcile the experience with any of the thories I know, but I have never got a satisfactory explanation. Some say it's psychometry, the ability to 'tune in' to an object's past and then translates it. But I'm doubtful, as my experience are ONLY with knives. My bet is that the same will only happen to a quite small number of people.
