reworked leftovers

[1442]

Made both of these from broken biface sections
the Georgetown blade is thick for a special request.
The notches stalled

this is a biface that I skint out of a piece of gravel. it was extraordinarily tough so I put it in a turkey roaster close to the edge and cranked up the heat to max for twenty four hours. If that helped it any I couldn't tell it. It was still tough, so I elected to use the ol 3/8" copper rod held under the knee indirect.
Heres the biface then the rod   shown with the biface with edges beveled and ground.
the last pic shows a stack getting started which I felt like was due to not enough grinding

I ground the edges more and was able to remove the stack and kept going.
That seemed to work well but when I tried to flake off the deltas the flakes would hinge
second pic has the edges pressure flaked and beveled to flake the other side

[1442]

first pic is the indirect pass on the second side. This time I would take one or two small alignment flakes inbetween the bigger flakes, This kept the deltas from remaining and made a better overall finish that pressure flaked better than the first side too.
second and third pics are the finished blade.

Nice! I tried flint knapping the other day and ALMOST got a small weird arrowhead. then... well I don't know? I just stopped and did something else!? well that's weird. one sec I got to think real hard about something.

dang,
I stop what I'm doing sometimes to flint knap
I hate having to stop flintknapping to do something else, that's just backwards
