It is an old belief that the best substances for making tools are those
that once had life in them, as opposed to artificial substances. Thus,
wood or ivory is better for a wand than metal, which is more
appropriate for swords or knives. Virgin parchment is better than
manufactured paper for talismans, etc. And things which have been made
by hand are good, because there is life in them.
