Lets be clear on this suchunclean entities are not interested in the tool; they are rather hungry and intrested in the person who uses such a tool.
As I have stated previously they do not play by human rules or logic. They can choose not to 'assist' one person who uses such a tool but stage a 'takeover' on another whilst with a another a spectacular attempt to un-nerve and spook will do.
Destroying such a tool is an outward sign of an inward spiritual intent to show you did not just say sorry to God you meant it. Its for this reason at some point most burn thier ritual tools and bits and bobs.
