(Note: if possible lay any new weapon touching an already consecrated one, Sword to sword, Athame to Athame, etc.)
 Prepare Circle and purify. All tools must be consecrated by a man and a woman, both as naked as drawn swords; they must be purified, clean, and properly prepared.
 Place tool on pentacle on altar. Magus sprinkles it with salt and water. Witch passes it through smoke of incense, replaces it on pentacle. Touching with already consecrated weapon, they say the First Conjuration.
[2a] For sword or athame, say "I conjure thee, O Sword (or Athame) of Steel, that thou servest me for a strength and a defence in all magical operations, against all mine enemies, visible and invisible, in the names of Aradia and Cernunnos. I conjure thee anew by the Holy Names Aradia and Cernunnos, that thou servest me for a protection in all adversities, so aid me."
[2b] For any other tool, say, "Aradia and Cernunnos, deign to bless and to consecrate this [tool], that it may obtain necessary virtue through thee for all acts of love and Beauty."
 Again they sprinkle and cense, and say the Second Conjuration:
[3a] For sword or athame, say, "I conjure thee, O Sword [Athame] of Steel, by the Great Gods and the Gentle Goddesses, by the virtue of the Heavens, of the Stars, of the Spirits who preside over them, that thou mayest receive such virtues that I may obtain the end that I desire in all things wherein I shall use thee, by the power of Aradia and Cernunnos."
[3b] For any other tool, say, "Aradia and Cernunnos, bless this instrument prepared in thine honour." (For the scourge or cords, add, "That it may only serve for a good use and end, and to thy Glory.")
 All instruments when consecrated should be presented to their User by giving the [point-down triangle] sign salute (if they are working in the 1st degree, or the sign of the higher degree if they are working that.)
 Then the one who is not the owner should give the Fivefold Kiss to the owner. For the final kiss, the tool should be placed between the breasts, and the two workers should embrace for as long as they feel like, it being held in place by their bodies. The new owner should use it immediately, i.e., cast (trace) Circle with Sword or Athame, wave wand to 4 quarters, cut something with white-handled knife, etc. Cords and scourge should be used at once.
The tool should be kept in as close connection as possible to the naked body for at least a month, i.e., kept under pillow, etc. When not in use, all tools and weapons should be put away in a secret place; and it is good that this should be near your sleeping place, and that you handle them each night before retiring. Do not allow anyone to touch or handle any of your tools until they are thoroughly impregnated with your aura; say, six months or as near as possible. But a couple working together may own the same tools, which will be impregnated with the aura of both.
