Dude, just break it down with your hands if you can't find the grinder lol! I always break weed up with hands anyway. I try to keep The only thing that should drive you mad is when you can't find your pipe, papers or lighter. Now that's usually what drives me mad and feel like an idiot. Especially when the lighter is in my lap the whole time and I'm lookin all around me. Please don't flame but IMO grinders are just a waste of money especially when you have free fingers and finger nails to break it down with. I try to have the least amount of paraphernalia on me..even in my own house. But I couldn't help it when it came to the pipe. I had to have it lol.
