These are my a b o tools. The small round stones are anvils that sit in my hand to prevent over shot. I use a number of pressure flakers. Most of the time I use an ishi stick. The tip on the ishi stick is approximately a quarter of an inch. I use it most for the rough pressure work. The small antler tips are used for the finer finish work. All finished edge work is completed with the ulna bone. Notching is completed with the antler tip that has been thinned. Copper and antler I believe are worked completely different.
