Cleft Stick: From Ancient Tool to Quantum Metaphor

The cleft stick, in its most basic form, is precisely what its name suggests: a stick that has been split or cleft, usually at one end, creating a fork or a "Why" shape. This simple yet effective tool does not have a single inventor, per se; rather, it emerged out of necessity in various cultures and contexts around the world. Its invention is lost to prehistory, a testament to human ingenuity in utilizing natural resources.
