The Monkey Fist at the end of my Thin Blue Line keychain is about a 1 1/4 inch in diameter and is center loaded with a 3/4 chrome steel ball. It takes roughly 7 1/2 feet of paracord to knot this item. The Cobra knot work is about 3 inches long and ends with a two inch loop and 1 1/4″ key ring. Great addition to your TBL collection! Have one for your squad car keys and one for your second/personal set.
