Great instructional video. How far up on the edge are you striking to get the Hertzian cone to develop. I've started late in the game, but now i'm addicted
I really have enjoyed your videos. Thank you. I have tried your methods and had only limited success. Is the continuous platform as effective as isolated ones with your methods/
Isolated platforms are needed more when the preform is relatively thin. The continuous platforms used in the video make the "Hertzian Cone" stand out so you can see it. I was trying to show the angle of the cone. The cone fracture changes to a "Planar Crack Split" and I tried to guess where the change over would occur also but I didn't talk about that part in the video. I drew a line where I thought the bulb of percussion would end. That's really ambitious also!
Thanks. you make it look so easy. Keep making the videos

@oldknapper Best I remember I was hitting directly on a (slightly) beveled edge.

I think it is kay county chert, probably heat treated. It is a wonderful awesome rock!
But actually I don't know for sure where it came from. Got it at a knap-in. Sorry...

i had a little at home, it makes such a distinct sound when you hit a flake off. i think mine might have had more fossils in it,
that stuff looks like butter!

I like to get a width to thickness ratio > 5 or 6. It depends of the point type.
