In my part of the country they didn't have the cone arrow points. That would be a pre-contact thing probably, where copper was available, and easily obtained. It would be rolled into a cone because a flat copper arrowhead wouldn't get the job done, I guess. Spiro had copper available from trade, but I haven't seen any arrow points made from it. Copper was pretty valuable in that part of the country, so they probably didn't use it for everyday items. Generally the historic tinklers I've seen have the tips cut off and are made of tin. Today, they make those out of those metal lids from Copenhagen snuff cans. Cool to see these posted.
