Well now you have a couple of arrow heads......
I don't know that any of us would have left it alone. Should have sent it to smarty pants, (Shannon) and see what he could have done with it.
I had a nice knife blade going the other night, and I just had to see if I could get a knife blade with just percussion, like Claude does, Well I was almost about to achieve it,
when that last little ridge, I probably could have pressure flaked out, decided to cause a break in the middle.
Oh well. Do you heat treat the whole rock, the spalls, or slabs, or a combination thereof? And at what temp. for how long?
