"This Monkey Fist unit looks like a simple harmless keychain. However, in the unfortunate event that you need to defend yourself this powerful self defense keychain will stun and maim your attacker." And how is that? Because like a monkey's fist this 550lb tensile military grade web of paracord is stuffed with the vitamins and nutrients of 1,000 bananas. And also a 1" steel ball.
The Monkey Fist measures about 9.8" long for use at both close range and farther away than other similar self defense tools. Maker Monkey Armor notes its cocooned steel ball is heavy enough to incapacitate an attacker upon impact (Monkey says go for the head, jugular, or sic balls!) but not too weighty to carry. It also comes in pink.
Given the Monkey Fist's paracord construction, Monkey Armor also points out that it could be unraveled for use in an emergency requiring a strong rope. Total length of cord used in the keychain is around 14'.
