It’s been around since before the middle ages, makes various types of cords. (most commonly a box cord. which unlike rounded cords is less likely to unravel, perfect for corsets ) The very shape is reminiscent of the devil or a stang. Usually made of wood or bone which can be carved. Its a type of waving that is repetitive and can be done in trance or when your mind is else where. I’ve used it for making witch ladders, bindings and protection charms. It’s super portable and doesn’t take much skill to learn the various types of cords, braids, or weavings. All around I’m honestly surprised more people haven’t raved about this sweet little tool so steeped in history!
