Iron nails are considered to ward off malevolent forces.
Iron carries a very powerful protective and disruptive energy, therefore can be used in protection magick and reversal (return to sender) spells
Take a look at most cemeteries, most (if not all) have iron fences around their perimeters, not only to keep vandals out, but also to keep spirits within.
Obviously for a number of reasons it is hard to come by real coffin nails nowadays, because to dig up an old grave is desecration, and you will upset a few people including the spirit in the grave, and possibly get arrested!
These cast iron nails have been traditionally hand made by a local blacksmith, then are soaked in salt water for 3 moon cycles and have been allowed to rest in graveyard dirt for a further 3 moon cycles.
