A bolline is another name for the "other"
knife. Sometimes cutting needs to be done in
rituals and
magick, but since that is not to be done with the
athame, a working
knife is used. You would probably use a bolline to cut an
apple in a
ritual, or to make
symbols in
wax or anything else you decide to cut. The point is that this one is not used to direct energy as the
athame is, but still it's usually just used for
ceremonial things, as in most people have one
special knife they use during their ceremonies and they don't throw it back in the kitchen drawer after they're done. Usually the bolline has a white or light handle. (Incidentally, mine is
silver.)
