What do you'all think? It's no lightweight at 2lbs 11 ozs, so I have to carry it in a sheath. Ok, a backpack.
It's made me a mini-celebrity around the office. If anything breaks, it's a sure bet that one of the 110 tools will be the correct one for the job.
Not only is it useful, but it's a great defensive weapon. Bounce this off the attacker's melon and they'll never bother you again.
