The Invention Of The Hex Cuff
One day this guy decided he wanted an ear cuff.
He typed "buy ear cuffs" into Google image search.
Digging, digging, and digging some more through the results he could not find a single cuff which would work for him.
He stopped and thought for a while.
It occurred to him that hex nuts are already the correct shape.
If he removed one of the sides it should do well to attach itself on its own.
He quested to the Hardware Store and picked out a few hex nuts to test his hypothesis.
He successfully battled and tamed his first Hex Cuff.
It worked better than he had dreamed.
He ventured out again, this time far and wide, in search of new types of hex nuts.
