What are those stick thingies called that you see at the RenFaires?

You know the kind that are two sticks in each hand and then a third stick that spins and whips acrobatically between the two others.
We watched a teen age girl flinging and whipping these thingies around the other day and it was hypnotic.

Is it hard to learn?

I’ve heard them called “devil sticks.” Dunno about the difficulty. Any kind of juggling looks hard to me. I’m a klutz.

Devil sticks.

I would have never found it under Devil Sticks. Thanks for the linkie!
