Where is a good place to sell these types of knifes?

I wouldn't sell mine but I have one that was given to me when I was a child by a friend of My Grandfather's who was a missionary in the Philippines during the Moro insurrection at the turn of the century.

I am probably the only one here that does not have any idea what one is, so I looked it up.

There was a better write up under Malaysia with the duckduckgo.com search, but the pictures would never load for me.

If we are talking about the same thing + I think we are, I have thought these were Kris daggers.

Traditionally in the American market they do not bring much. Shame, some of them have really interesting work. Quite the legend on them as well. I made one and that was it.
