Vietnamese talismanic knife?

[Sajen]

Interesting item! But not a betel knife. Would like to see some better pictures. The handle material look a little bit odd, would like to see some better pictures when you have received it.
Hamster bone : Barry has written recently in a other thread what people used to describe ivory in ebay and it seems that one seller has described it as hamster bone!
