Athame

An athame or athamé (/əˈθɒm/, /ˈæθəmeɪ/ or /ˈæθɪm/) is a ceremonial blade, generally with a black handle. It is the main ritual implement or magical tool among several used in ceremonial magick traditions, and by other neopagans, witchcraft, as well as satanic traditions. A black-handled knife called an arthame appears in certain versions of the Key of Solomon, a grimoire originating in the Middle Ages.
