I know we have a herb grinder thread but let's dig a little deeper in that discussion. As the title states, which type of grinder do you prefer, two or four piece and why? If your feeling fancy, include the name of your favorite grinder, whether it be spacecase, cosmic, Santa Cruz ect. I'll start. As of right now my preference is a medium two piece space case. I like the two piece because I can grind it up really fine or chunky depending on how I need my herb(versatile!). Also, I have a kief box so I don't think I need a four piece for kief. Look forward to FC's thoughts as I'm in the market for a new grinder and it will help others too!
