Few additional comments for discussion:
As said earlier the figure carved on the gandik is called Kalarau and it seems to have been introduced recently (refer to the book from Neka) but I am not sure. From the pics I can't see if it is integral to the blade or welded separately.
The pamor pattern is not complete but it looks like the Javanese pamor Pandan Iris (sliced pandanus leaves).
The figure depicted on the hilt seems in Chinese style and the base is very short.
Other opinions will be welcome.
