"A monkey fist has a variety of uses, including its original purpose as a weighted knot to help sailors throw lines, as a self-defense tool (known as a slungshot), and for less aggressive uses like a keychain, dog toy, or home decor. It can be used to add weight to the end of a rope for throwing, act as a handle for parachutes, or even as a decorative object like a bottle stopper or ornament. "
