The card includes a glasses screwdriver, letter opener, nail puller, ruler, bottle opener, can opener, box opener, cell phone stand, hex nuts and bolts, screwdriver, and fruit peeler. Critics say it’s TSA-approved, but some people had to take it out of their bags and attach it to their belts for safety.
Promising review: “This is definitely useful to have on hand! The Ninja is small and slim, but it punches above its weight class in terms of practicality. All the tools are the kind you’d find in a drawer; It’s useful in a pinch. It fits comfortably in your wallet and helps you open a beer or tighten a screw. The best feature that other similar products don’t have is that it’s perfect for airplanes and other travel applications. I’ve never had a problem bringing this on a plane anywhere I’ve traveled so far, FYI)” — Mary
“I bought this as a gift for my husband. I can’t tell you how many times this little card has come in handy. I take it with me when I travel and end up using it all the time.” —Andy Aguirre
