This Elite Forces Monkey Fist is the ultimate personal protection tool. Often used in the 1800s by sailors and gangs in melees, the Monkey Fist is still an effective form of protection today. This Monkey Fist is tied with heavy duty paracord. The inner core is constructed of a 7/10" (approximate diameter) steel ball, so when needed, this device thwarts any attacker. The paracord loop affords versatility. Key ring not included.
