I do'nt understand the ? You look like you are making great,functional points.The knife blade looks good too.A guy can make points too fat in the middle and they won't sharpen up real good,Also a guy can make them really thin and while sharp,they snap pretty easily. Through trial and error,I have found a 5 or 6 to 1 ratio on obsidian to be about right.I can get them cut you now sharp and they seem to hold up right to the time I shoot them into a rock.I'm doing 6 or 7 to 1 ratio's now on some flint points and I think those are going to be killer.Flint does'nt seem to get as sharp as the obsidian edges but,I was cutting up my steak the other night with a flint blade,no problem.Looks like to me your doing good.I use antler exclusively on obsidian but have been doing a little fine flaking on the flint edges with a thin piece of copper wire so I am not constantly regrinding my antler point.(Just being lazy) I do use rocks for percussion on really big stuff but I have gotten me a moose billet about done,so.....
Thats all I got ! Frank
