I know you all know just how much i hate making controversial statements
but if you ask me, books, especially those written by Westerners on the subject of Indonesian weapons, aren't worth squat when it comes to the proper naming of the various weapons in question. Add to that the great variance of names applied to these weapons by the many different groups of people who use(d) them and live in this area of the world and we are left with MUCH confusion. I'm with Marto. I'd call it a Balinese knife.
There are certainly MANY errors in the writings of Stone, Raffles, Tammens and others. This does not make their works useless by far, but i think it is important that we take care not to assume that just because it got written down and published that it must be right.
