The monkey fist knot is very popular for key fobs and decorations, but can be a bit tricky, however the Monkey Fist Tool makes them very straight forward and quick to make.
Made in the USA from hard maple wood. Contains one key ring and plastic ball core to make one monkey fist key fob.
Requires about 8 feet (2.4 meters) of 550 Parachute Cord to complete one monkey fist (not included). A finished monkey fist keyring is about 3.5cm wide.
