There is a new two-volume publication on the market, "Drawing The Sword" from Karel Sirag, not cheap but heavy books and worth buying when you are interested in Indonesian blades. The first volume is about Sumatra, Java and Madura, the second volume is about Bali, Lombok, Nusa Tenggara, Moluccas, Sulawesi and Borneo.
With some pride I can say that some of my blades are shown there as well, especially my Halmahera blades.
