You can either make your tools by hand and already have them charged with your energy, or you could get a tool already made and charge it with your own, cancelling the previous bond.
the school of belief is that traditionally, you should make your own as it is then charged with -your- energy. but this can be hard if you are looking for a specific wood(for wards) or mineral(again for wards) most people do not have the metal craft ability to make their own athame. you can purchase your own. cleanse it and "charge" it.
Sacrifice animals. You have no idea how often I been to my aunt's house and animal corpses have been around. Goat heads, chicken feet, the works! I spent one Christmas accidentally witnessing the beheading of a rooster. Yesterday they grabbed a baby bat and trapped it in a cup, lord knows what they're gonna do to it!
whoa...that is not what most people in the neo-pagan circles practice. most believe deeply in the "harm none" philosophy. there are people that do sacrifices but it is NOT the norm. nor necessary.
I've read a few different things concerning the tools of witchcraft, such as the wand and the athane.
Do you think it is necessary to make the tools yourself? What is your opinion on buying tools?
