Remember the blessed St Benedict Cross medal is an exorcism medal. I wear them. I also have two St Benedict rosaries. I gave a blessed St Benedict cloth and medal to my friend because his wife at the time was a spell caster. When he takes it out of his wallet his wife would fall by unseen forces on her rump. It is powerful. I got it from here.
