Boline

A boline is a knife for practical use. Traditionally, it has a white handle and a curved blade. You will use it to harvest flowers, cut herbs, branches, thread, or to carve symbols on wood, wax or clay. Basically, the boline is used to to physically cut any materials before or during the casting of a spell.
Its white handle will help you distinguish it from your athame. Also, it’s usually smaller and with a single edge, which can be serrated or smooth depending on the owner. In this case, a kitchen knife can also turn out to be a great option. If you want to step up your candle-carving game, you could also get a candle carving toolkit.
