Please, to explain, kind Sir

The left one is cleaner and narrower notched....You have figured something out. Nice work

[iowabow]

The big different here are the notches. I learned to make notches that worked well for hunting but not great for the narrow notches seen with the cahokia grave points. So for the last couple years I just figured that they must have used copper.
I came to this because every time I would try this the tool would get a couple flakes off and then the tool would break. So now I approached from a different mind set.
First I thinned the ulna for narrow notches and rounded the end.

This is where it gets interesting because if you keep notching the tool breaks.
Step one ...take notch
Step two...round the tool to remove small dint
Step three...take notch
Step four round the tool to remove small dint
And so no and so one....tool doesn't not break

This creates notches thin like copper.

The rounding only removes small amount of tip but is a very important process to prevent the tool from blowing up!!!
Simple only took 4 years to figure it out!

If you look at the center notch you can see how much power you can deliver if the tool is dressed properly.

In the past I talked about not dressing the ulna bone and it is true that you need not do this if you are just making down and dirty hunting points but if you are going to head down the narrow road you're going to need to do more that just thin the sides. Dressing the end and keeping it dressed is the trick
And yes Scott stay dressed if you're going to walk the narrow road...got it?

what a great achievement

i'm excited; so i can only imagine that you are more excited than i, hah hah.

I must admit, "keeping dressed" has been a motto of mine.

Just get you hands on some form of ivory and narrow notches are easy  Especially if you aren't doglegging and whatnot.
