Looks very similar to this (Parang Ginah):

When I saw it (the one you bought), I assumed that it was an agricultural tool. Looked nice, but I have enough sickles/billhooks (I don't really collect them, just use them as tools).
I assumed it was probably European, but your question made me look more closely. I can't find any close European match, so perhaps it is a Parang Ginah.
