I started with a basic stemmed point made from obsidion. I used cane shafts and ended the shaft at the top of the stem. I had two break at the top of the stem where the shaft ended. One dead hog, one lost hog. I also killed a small buck with that but couldn't find the arrow. I switched to a side notch. I have killed a deer and two hogs with no problems. I made some Dalton style points for some people to use, several people have killed critters and no one has reported anything lost due to breakage of the point. The side notched and the Daltons were wider than the shaft for a little more strength. I also switched to chert, I prefer Texas cherts but I also use Kentucky Blue, hornstone, and Buffalo River. Bill
