String puzzle
Appearance
In a string puzzle you have to manipulate a piece of string or rope in a certain way.
Usually this involves disentanglement of a knot (which make it an disentanglement-puzzle) or the creation of a knot (which make it an entanglement-puzzle) or both.
Surely the most famous string puzzle is the Gordian Knot, which Alexander The Great solved using brute force by severing it with his sword.
