A knife as a present

 

Any sharp cutting or piercing instrument, like a knife, scissors or pins and needles can easily do damage, but their danger is multiplied if in occult belief they are empowered by black magic.  

How easily thus at the very least, a knife given as a present could cut friendship. To end any such potential evil, the recipient of the gift presents the giver with a small coin. This subtly changes a free gift into token purchase, thereby defusing a possibly aggressive weapon.
