Besides being the coolest fashion accessory at the gym, this dog tag also includes a barrage of tools that will help you fight off the killer attack ponies, who happen to have their secret lair at the gym. This dog tag multi-tool includes tweezers, a knife, a file, a bottle opener, a Philips screwdriver and even an LED light—you know, for the killer pony attackers who are afraid of the dark. All of this is housed in a stainless steel dog tag that is only a fourth of an inch thick. Unfortunately, they don't do custom engraving for the dog tags. You didn't want derogatory killer pony comments on your dog tag, anyway. $32.
