Sam,
I am not sure how your quest is going, but this sounds like a fun project. I may be able to help. Those blades are very similar to the ulu which is used up here, except the ulu is only beveled on one side of the edge.
Shoot me an e mail if you would like to talk more, I would love to make some.

Oh yeah, I have a fully stocked Avallo in my shop, so this really caught my interest.
