Sad to say but being Native American and not knowing how your people lived and survived day to day is how I grew up. Now I live to learn and perfect those skills and abilities and pass them on to my children and any who wish to learn.
A bone point, more native cultures used bone to make arrow points, dart points, knife blades especially if they couldn't get any chert or flint. They would bust up the long bones and using sand stone or such file the bone into the desired point. Heating the bone also hardened and allowed the sharp edge to remain sharp. Many of these techniques I am sure came about buy trial and error but they did work because we are here today.
