Two very nice hits indeed. I'm agree with Lennythesmith : one is Navasari, the other is Rangda (or perhaps Rangda's sister). Ganjawulung are the hits from Madura?
No Marco, it is from Bali. Wooden hilt material. And this other one below, is made of "balung" (bone). Another motive of Ganesha. I bought it from a "mranggi" (sheath maker) in Batuan, near Ubud, Gianyar...
