it made me leak, lol. I was trying to just make a point out of it cause I told bearbowman if I couldn't make a point outta the quartz we found, I would quit flintknapping. Thats just not gonna happen until I'm unable to flake any material. this was a first for me. One thing for sure it won't break. and is sharp as hell. may look bulky, but I wouldn't want it coming toward me. this material has alot of freeze fractures. it even had some clear chrystal quartz mixwd in with it. Easy to flake at first but as it got smaller it wouldn't cooperate.
