Wallet Ninja Credit Card Sized Multi-Tool

What to say about the Wallet Ninja... The bottle opener works in a pinch or if you are lacking a smoker friend (with their pre-requisite chipped Bic lighter), but if you're not careful, you can hurt yourself on the "wrenches". The cell phone stand is useless and does not work. Period. The ruler is, well, a ruler. I have not had the markings lab-certified for accuracy. If you need to measure something less than 3" long, this is your go-to. Most of the other functions are likely present to simply up the function count, but don't even come close to a real tool or even a Swiss Army Knife/Leatherman in most cases. But you can't put those in your wallet now, can you? While I have not personally attempted to smuggle my Wallet Ninja onto a plane, I'd imagine leaving it absentmindedly in your wallet while going through the x-rays at TSA is a good way to get a free government-mandated groping. I have a hard time believing that it would be useful in opening the armored cockpit door or taking a hostage, however.
