How to Do Basel Grinding

Hi, I'm John Olsen for Expert Village. Well we've got this knife done. It's fairly wide. When it's hafted it can be sharpened several different times and it'll get thinner and it'll actually turn into a projectile point. A lot of people think these are spear heads. Throwing something that takes that long to make and will probably break the first time you throw it, it wouldn't be very economical. So, most of these were used as knives. There's one more thing we have to do to this, it's pretty sharp. We have to prepare it for hafting and basically these notches and this bottom part are going to be stuck into probably a piece of wood. It could even be stuck into a bone and wrapped with some kind of cordage, pine pitched with any stuff. But a lot of points, if you feel the edges on the cutting edge, they're fairly sharp sometimes, but the bases, is what we call basal grinding. Basically it's just taking your hammer stone and grinding the edge so it's fairly dull. So it doesn't cut your cords or whatever you put on there. Keeps your bindings from being cut and you can go inside the notches. Kind of grind them out a little bit. Cleans them up a little bit. Makes them so they're not sharp. They won't cutting anything that you tie it to. We have a finished, knapped piece of obsidian. This is the piece that came out of the rock, right in there somewhere and we have all this, what is called debutage, left over pieces, that could be made into other things.
