Pretty points, bubby. They look like they'd work great and
really nice for your first points!
Just want add 2 cents to help clarify,
There are hundreds of different types and ages of rhyolite around the world.
They don't all look or knap the same. Bubby's pieces pictured here are
most likely from the southwestern states, New Mexico, Arizona, etc.
The rhyolite in NC, for example, is completely different.
