Hi Javagolok,
Welcome to the forum.
I agree with Henk that it looks like a
tombak (spearhead) mounted on a Javanese badek hilt. The
metuk iras (carved ferrule) looks thin compared to a standard metuk. Normally a javanese spearhead have a longer
pesi (tang), but not this one.
VVV's tombak kujang example
My 2 cents worth.
