The mortar and pestle set is a handy tool that many Pagans — and other folks — use for grinding and blending herbs and dried ingredients together during a magical working.

The wide end of the pestle, which is shaped a bit like a baseball bat, is often roughened to aid in the grinding and crushing of herbs, resins, or whatever else you may be working with.
