Quite interesting.
In van Zonneveld's book there is a somewhat similar blade depicted and named as "Kudi Tranchang" from Bali on page 76. Regarding the name, please read the post #21 here:

I agree, that the blade has a strong Balinese flavor, yet the handle absolutely not. They look nice together, yet the combination is in some way cross-cultural. Similar handles we could find on Sulawesi, Java and Sumatra, perhaps even Malay Peninsula.
