I am attempting to show a Black Diamond model. Anyway, I went and looked in my mountain climbing gear and found 4 units that were 4 inches each. Put your four fingers through on a hand and you have the equivalent of brass knuckles. Light weight. Non threatening. Slip in a pocket. You don't worry if you lose one as they are about $20 a unit.
