Cowboy, that looks like some of the black dover that Jesse had. I ended up getting a 5 gal bucket of it an it works pretty good, the dark black seems to be better than the grainy tan colored stuff also Jesse told me soak it in water a few days before working. I like it and I like the point you made with it, doesn,t look like you had any problem at all with the Dover, Makes a real authentic looking point. I need to get into the stone I got from you an see if I can make something decent. Bob
