A cannabis grinder helps cut through dried cannabis flower. Typically round and filled with small prongs, grinders help break down cannabis quickly, as well as sort out and collect the potent kief, which is often wasted when breaking up buds by hand.
Grinders can be made out of a variety of materials:
- Metal—expensive, but durable
- Plastic—cheap, but breaks easily
- Wood—usually more attractive, but hard to clean
