Hello Rick,
the seller respond to my query like this:" Yes, The Ganesha Hilt is made from Areng Wood,you can see the inside of the wood from the pesi hole, it's all black.or try to make to pesi hole bigger, than you will see the small piece of the wood from the drill."
And further:"Please note that Areng Wood id different with Ebony.Ebony much harder than Areng wood, and Areng wood is somekind like altenatif of EbonySince Ebony is hard to find the material and the moment and Areng wood is way much easier to carved.So Areng wood is the favourite wood for carving at the moment."
I have asked him if the hilt is from Kayu Areng since I have thought that it is Ebony but it seems that I am wrong. I think that in Indonesia is black wood is just called Kayu Areng.
Regards,
Detlef
