Wiccans use several different matrials and tools for performing rituals and magick, as well as other things. These are the primary tools for Wiccans and some brief info about each:
Athame: a cerimonial knife, the athame is one of the Wiccans most important tools. It is traditionally black-handled, and double bladed. Should never be used to cut anything but energy.
Alter: a table or shelf dedicated to Wiccan practise; holds tools or other items important to the Wiccan.
Broom: a tool used to cleanse an area spiritually before drawing a circle.
Cauldron: a three-legged pot (big or small), can be used for burning insense, mixing herbs or simpley representation.
Chalice: a cup used to represent the woman's womb
Wand: similar to the athame, used to draw energy and often used to invoke the gods
Utility knife: used to cut things
Statues: used to represnt the gods
Book of Shadows: typically a personal diary/spell book
Candles/Incense: candles are used extremely often, and incense is used often to represent air and to 'set the mood'.
