 Similarly, sometimes a white-hilted knife called a "kirfane" (various spellings) is used, for roughly the same purposes as the boline.According to the Kitchen Witchcraft philosophy, the use of magical tools for mundane purposes like cooking is actively encouraged, and as such there is little or no need for a boline as a separate tool from the athame.Some traditions, such as that of Robert Cochrane, also prescribe the use of a single knife for both ritual and practical purposes.
