The Monkey Fist makes for an excellent personal protection tool. Often used in the 1800s by sailors and gangs in melees, the Monkey Fist is still used for protection today. This Monkey Fist is tied with heavy-duty 300 lb. paracord. The inner core is constructed of a 1/4 in. steel ball so when needed, this device thwarts your attacker. The paracord loop allows versatility and it works great as a key chain or knife fob.
