I am actually with Joe on this one. That thing is goofy looking, and I am not willing to carry fifteen bucks worth of quarters with me where ever I may roam.
Of course, I have the advantage of being one big, mean looking SOB, and that is usually enough to take care of any less lethal situations that arise. If it isn't, I am no awesome fighter, but I can box OK and I went to state as a wrestler some 20 years ago and recently started coaching that sport again. Point is, I can punch, and there aren't statistically a whole lot of people out there that are going to beat me grappling. Thus, 15 bucks of quarters in a goofy looking belt sack isn't in my future.
Besides, a bottle of water in a plastic bag beats that sack of quarters any day of the week. Also, I am not calling you a liar, and you seem like a heck of a good guy 451Detonics, but I have a hard time believing that 3/4 of a pound of sack quarters is going to mow through a 2x4. I will try it though, and if it works, I will apologize immediately and sincerely.
