lenght of hunting points?

Thanks for the offer Tracker! That would be cool to see that preform cast. Would not want to interfere with any business venture you have with my hobby. But that would be interesting to size up bifaces or even spalls and flakes to see if they have the size at the start. Let me know when the snow melts. Thanks!

I hear ya Allyn. I don't have a time table anymore. Only when I feel good about my equipment is when Ill take it out. Learning/perfecting the skills has been alot of fun over the years.

BJ, hope to try a few flakes of obsidian again soon. I would like to make an antler pressure flaker 1st or spend the few minutes to sharpen up a tine. I have had my best success with that stuff with an antler billet I made but have not made the time to make a quality tine flaker so was putting too much pressure an breaking things in half. But been using copper on any other stone so far.  Have yet to get indirect down, worked at it a few weeks ago and think I determined I needed to change the angle of contact but have not got back to that yet. I can see how it would be a useful skill to have.

Mike I like antler and stone for obsidian to. The antler seems a grip the edge better and I have less crumbling.
 It took me a while to get comfortable with indirect. It looks so easy, but it’s hard to get comfortable. I find I do better if I put the point to the tip of my flaker rather than put my flaker to my point. I also have better flakes when I put inward pressure with my legs to drive a longer flake. That’s  why I put the point where the flaker is. If I put pressure against my edge I don’t slip off it as bad that way. I’ve more than once slipped off edge to center of point just as baton was coming down. Ruined my points

PS it seems to help if I strike flaker close to its end and not in just in the middle of it

M2A:
Appreciate all the information from everyone in this thread. Going to keep working at it. Here's what I come up with to this point.
Thx, Mike

those look nice.. deep big serration are hit or miss .. some tend to grab hide and hinder penetration.. I try to keep mine micro serrated.. but those look nice.. ratio looks good too... for pressure flaking obsidian it is critical to abrade well..I use a callahan pad or a pad that has built up edges with notch cut out of center.. really helps with a well abraded edge to put enough pressure on the edge and drive a long flake to center with out the edge crumbling.. once a good straight trued edge is set I can come back with a horseshoe nail of tiny point antler to do micro serrating and keep that trued up edge straight.. congrats on your heads.. gut
