When you have tried a grinder you never want to go back to preparing your herbal blends and tobacco with scissors or fingers again. A grinder (or herb mill) is used to quickly and easily grind your herbal blends to a fine consistency that burns nicely in your hand-rolled cigarettes, in the bong or pipe. There are variants in different sizes, kinds and materials where the most common ones are made of steel or aluminium. If you want to save money you can buy an acrylic or wooden one. The most common ones are made in two or four parts where the latter has a special bottom chamber where all trichomes (kief) is collected for future use. Choose size depending on how much you prepare at once - if you're a big-time smoker we recommend the largest models. If you want a compact one for bringing on adventures there are extra small models in two parts which easily slide into your pocket.
