So.... I finally cabbaged up a little Rhyolite to work threw. Not sure the quality yet but I did hit a few spalls off with a hammerstone, and it hit back...😲
This stuff might knock me out of commission.😁

Looks gnarly, but the points will be cool. What does “cabbaged” mean?

That stuff doesn't look friendly. It'll have a lot of character though if it cooperates with you.

That really is some knarly stuff but if you can get anything out of it they will be some really primal looking points!

Lol, I have been interested in this stuff ever since I held a Clovis base made from it. I have only found a handful of artifacts made from our Rhyolite but last weekend at a local rock swap I was gifted this Etley base. They are my favorite type from my area.😁photo share
Now I want to make a whole one.....lol

amazing job considering the material. from my understanding, the "grain" size of stuff like that is based on how slowly it cooled, so perhaps if you seek out the sources of the stuff and test hit a bunch, you'll eventually find a piece or three that are just better than others as a result of slightly different composition and/or cooling. i've worked rhyolite from a couple of different places out west but it was finer grained.

That looks like a pretty rough grade even by North Carolina standards but I like the looks of it. Have you tried wood billets on any of it?

Where I live in SE Missouri most of the points ya find are made of rhyolite, there is some that is very fine grained and not as tuff to work, what you have looks to be some of the tougher stuff. so good job.

Here is an even less quality wood billet flake point. I used antler for both percussion and pressure.upload image[url=https://postimg.cc/image/h7ga6pw5n/][/url]

Given the nature of the material I consider that a fine point.  And I think it's to your credit that you're focused on meeting the challenges of the rhyolites.

Gets me to thinking about the novel satisfaction of wood meeting hardstone.

Cornernotched, that looks like nice stuff, almost looks like Chert. I have yet to find anything of that quality.

Around here I find alot of different types, some that looks like what you have, some that is kind of black with specs of pyrite, and some that is like the stuff in the pic and if you knock off a thin flake it's almost translucent. but it's all alot tougher than Chert. If I get time tomorrow I'll take a pic of some of the different varieties I find.

Not a thing wrong there.  The blade edges look very thin and sharp as does the base.  That's all you need.  The "second string" type materials will always have some weirdness in them due to defects in the material you can only fight so much.

That stuff looks very much like Mt. Kineo rhyolite, which is funky stuff and does seem to work best with wood.  The stuff cornernotched shows looks very similar to the good grades of North Carolina rhyolite, which is wonderful, "flinty" stuff that can be worked like any other material.
