"You talking about the knapping site?"
Yes I am pretty sure, can't link because of rules but they seem to specialize in knapping and arrow making along with other primitive crafts, it's the first website that comes up when you google "native ways".
"Some of the best prices for staves come from Kerry Brinkley (kerryb). I've been paying between $45-55 and actual shipping which usually comes to $11-12. He's also a serious bowyer, so if it ain't good enough for him he burns it for heat."
Do they have a ebay site or something? I couldn't find any staves on the site store for nothing.
