So ive been wanting a monkey fist keychain for awhile now. I just thought they looked neat. Me and my girfriend were at a gun show last weekend and saw some so she got me one. I had no idea these things had a steel ball in them. I thought it was just a knot. Anyway the guy selling it was talking about using it as a weapon. What do you guys think? It may make somebody mad but i dont know about stopping them. Maybe if you hit them in the head a couple of times?
