Thanks a lot y'all. This is having fun to me, and stopping to take pictures really helps me to knap better than if I just sit down and knap too fast.
Tower,
I think you are referring to a brownish colored triangle shaped blade that I just kept working on with indirect percussion on a 3/8" copper rod until there just wasn't much left of it. I expected it to break with every hit towards the end but it never did.
I even videoed the making of that blade from start to finish and was gonna put it on you tube but have held off until I learn to edit out a lot of boring time spent beveling the edges and stuff. The video is like at least an hour and a half and I did a lot of talking about what I was doing too that sounds not to good.
