Unusual tanto in the shape of a dragon

[Henk]

When my grandfather past away 45 years ago one of his possesions was a tanto in the shape of a dragon. I had never seen something like that and never saw something like that again. One of his grandsons inherited the tanto. I hope he still have the piece in his posesion.

Today i was able to buy a similar one. To be honest, i feel very lucky. Can anyone of the knowledgeable forummembers tell me more about it?
I don't have it yet but here are some pictures of the seller.
