Have you ever put together any traditional arrows with them?
(Hand cut and wrapped fletchings, hand wrapping to attach the heads, etc)

I never had the time to sit down and try napping myself. I should considering I have a fairly good source of agate/flint. Just have to go to my aunts house and dig in her back yard and can get nodules up to 12".
Now Obsidian would be nice. Sharper than surgical steel when done well.
