|Used as a self-defense tool, looks like a small bunched fist. Tied at the end of the string, inside the knot, is a metal ball making it easy to throw. These things can crack glass, metal, skulls or whatever you can throw it at. Don't let its innocent look fool you; these self-defense Monkey Fists are always sold-out because people are arming themselves with the newest addition to the self-defense family. The paracord is designed to be extended or shortened for your own desired length, so each Monkey Fist is customizable. And it also doubles as a survival rope in case you find yourself in need of strong and durable string. Get yours now before they're all gone.
