I'm confused by the bad reviews here, I guess not everyone in the market for this tool also has a magazine grinder. Balls are good when you need that and when you don't then our friend the shop grinder comes to the rescue. Within two seconds of meeting this guy, our worried little balls crumble to dust. The problem is solved. So actually you have the option. I also like the fact that the smaller sizes have indentations on top for your finger to spin.
