A boline is typically a curved dagger (although not necessarily) with a white handle, and is used for cutting grass, flowers, branches from trees, writing labels on candles and the like. The boline must be well sharpened as opposed to the athame which can be rather blunt. Boline handles can be decorated with precious stones.
The boline is not a mandatory instrument, as it doesn’t have the strong presence during rituals and ceremonies. It is usually smaller in size than an athame, and should be carefully chosen to sit comfortably in the palm of your hand.
