What is your most used tool? Why is it the most used?

I would have to say my most used tool is my cauldron. I use it for almost every ritual. I love the classic vibes a cauldron gives off. There is something extra magickal about putting each herb in one by one, burning your intentions and stirring up your desires in the flames. I enjoy the weight of a cauldron. I actually own several small cauldrons and am on the hunt for that special big one that I know is out there just waiting for me to find it. Until that day, I have purchased a large cast iron pot for my bigger ritual workings. The cauldron has long been a tool used for cooking and making magick.
