An athame or athamé is a ceremonial ouble-edged knife, one of several magical tools used in Traditional Witchcraft and other pagan beliefs and religions such as Wicca for various ritual knives. It is variously pronounced /ˈæ.θə.meɪ/, /ə.ˈθeɪ.miː/, etc. A black-handled knife called an arthame appears in certain versions of the Key of Solomon, a grimoire originating in the Middle Ages..
