How to Sand the Edges of a Rock

"Hi I'm Jason with Expert Village.com. We're making the rock polish charm necklace. We've drilled holes, we've beveled the edges of the holes, and we've hit every surface with the cutting tool, and now for the last step of cutting we're going to do the edges. And I talked about it before. As you get the polish on, if you have a sharp edge like this, the more you polish, the edge is really going to become actually sharp. You're going to cut yourself. So what you want to do with the edges is, if you want a smooth edge like this, rather than a rounded edge, you could still do it but all you have to do is go along the edge really quick with the cutting tool. And at this point, when you're doing the edges, you can do shape. If you want this line here a little bit more caved in, you can still just take a little divot down in there at the same time going over the top. And that will make everything all smooth all the way around. If you want it rounded, obviously just round around until you get it the roundness you want. I like my edges sharp and flat, so that's what we're going to do in the next step."
