It is as they say, a weapon forged is a weapon forged.
Weapons range from physical armaments to spiritual armaments. In Witchcraft, a weapon can take the form of a simple candle spell to an incantation. A weapon forged against you, can be an elaborate ritual or a simple prayer.
No matter who crafted the weapon used against you, or no matter who orders it to be used against you, a weapon is a weapon, is a weapon forged against you.
