I struggled to take pictures of this cone shaped stone.
Just didn’t look right. Sorry about the rotation issue. It looks right when you enlarge it.

Do I have this correct? Used up Jasper Micro Core? Looking for validation.

Better?

Looks pretty good. Your strike angle is a little too oblique to knock the nodule in half but that's all I'd change. To knock off blades, you put the polyhedral core between your knees with a cloth or leather wrapped in a loop over your knees and under your feet. You tighten the loop by spreading your feet and this holds the core steady while you strike off the blade. I'd probably have to take a pic of the setup for you to understand my description better. I have a video of Archie Peter Ainsworth from N.Mex. doing it. Gary

Mainly I wanted to verify the flake core? I found was representative of what the sketches were depicting.

The sketch was ripped off the internet just an example to help show what I was thinking..

It’s a small core (I think), but I have remembered the advice offered here, that Jasper was a highly desired lithic as far as durability is concerned.

Not that long ago, I would not have appreciated it for what it is.

I will do a little searching to find a video of someone actually doing the work you describe.

Classic core example, or am I letting my imagination run away again?

Is it a discoidal core?

I'd say it's a polyhedral core.

These pictures give a better sense of the size.
Very small. Makes me really think about the purpose of those flakes of Jasper that are sharp, but seem too small to be useful. They must have had a purpose.





I kind of wonder if these small flakes could have been wedged into a crack of a stick and used like an exacto-knife-blade rather than held with the fingers? Otherwise they seem kind of small to hold?

Extremely used up conical blade core IMHO.

Extremely used up conical blade core IMHO.

Thank you. It definitely looks like it was used by a very frugal or maybe poor person.
Used up as much as possible until it was discarded.

I'm not sure if this piece matches your illustration it seems to have some similarities. I find Red Jasper flaked tools here Sf Bay Area but not points.



Another piece worked on both edges both Uniface.
