This Monkey's Fist Keychain is made with 100% cotton cord for a more traditional look and is 3 inches long, the perfect size to hold your keys. Monkey’s Fists are a traditional seafaring knot used as weight at the end of a heaving line. The heaving line is used to pull the dock line to the pier. This knot is tied over a 3/4" maple ball covered with cotton cord monkey fist knot and finished with a solid brass American made split ring. Show off your nautical style without adding extra weight to your keys.
