I'm really sorry that you have had to wait so long for some of us to respond to your question Milandro. A few hours can certainly seem like a very long time if one is stuck in an airport lounge or a bus-stop waiting room. 
 
I cannot comment at all on who the character on the hilt might be, it is not any sort of traditional cultural depiction, & I believe only the carver might have some idea of whom it is supposed to represent. 
 
From the photo of the blade I cannot tell if I am looking at pamor mlumah or pamor miring. 
 
If it is pamor mlumah, it is as YS has said, wusing wutah, sub-category ilining warih, if it is pamor miring I don't know precisely how it should be named as a Balinese motif.
