Katadesmoi in plural, katadesmos in singular are an ancient hellenic magickal technique. It requires a lead tablet and a nail. The desired purpose is simply written in the lead and then it is fold in half and with a nail on the center it is bound. The instructions of how to make a lead tablet efficently for magickal uses could be found in ancient papyri and ancient tablets.

There are some basic structures of creating a binding, but in this article I am just going to provide the instructions from the PGM V 304 - 369 This papyros is stored in the Museum of London, not in Hellas. For the following katadesmos a papyros is needed, plaster, calamus pen, myrrh and threads/cords. It can also be done with lead.
