Some covens hand out sets of tools to new members. The rule is that to use a tool, it must be either handmade or received as a gift - not purchased at the store. Also, the tool must be initiated by casting the circle and welcoming it in. Another rule is that these sacred tools must never be used as weapons, and if they for some reason draw blood, they must go through a purification ritual. And, like a Book of Shadows, tools must never be handled by anyone besides their owner.
Unlike most religions, Wicca has no use for churches or fancy buildings. It is believed that all of Earth is sacred, and any place is a good place for a ritual, provided the circle is mapped out. When a suitable area is found for a spell or ritual to take place, a witch pulls out her athame and makes the circle. The sacred circle is simply a place where religious deeds can be done safely without any evil spirits coming in and interfering. The circle is made outside whenever the weather is permitting, but inside will do just as good. When the ritual is completed, the Goddess and God are blessed, and a mini-feast is held in their honor. Then the circle is re-opened.
Witches can get mad, just like anyone, but they are sure never to use their magickal powers to harm whoever they are mad at. Why? you ask. Well, it is simple. Witches believe that all magick returns to the sender three times. So, if a witch casts a spell to break a person's bone, he or she will get three broken bones in the end. Now, isn't it better to be mad than to be in a cast? Also, using magick for evil goes against the Wiccan Rede, which is like a golden rule for witches.
