Thanks all. I brought them into work this morning where 1 person declared the obsidian point was my best yet. Struck me funny. My work friends are really easy to please.

The obsidian has me stymied. Seems just a slight difference in angle changes the flake from a step to an overshot to too shallow. And, whatever the worst possible outcome can be seems to be where I naturally go.

Seems to need more abraiding too. And then there's the bleeding...

Makes pretty points though.
