Australian euphamism for a herb mill used to grind choof (
marijuana). Also known as a Muller, its purpose is to increase the
surface area of the material, so that smoking or eating it will bring out more THC.
Made from metal and/or plastic, choof choppers come in many shapes and sizes. Some have a box attatchment to catch the material. The main problem with choof choppers is that they can get clogged easily if wet tobacco or choof is put into them.
