The card includes an eyeglass screwdriver, letter opener, nail puller, ruler, bottle opener, can opener, box opener, cellphone stand, hex-head nut and bolts, screwdrivers, and a fruit peeler. Reviewers say t is TSA-approved, but some had to remove it from their bag and put it on the belt by itself just to be safe.

Promising review: “This is definitely helpful to have on hand! The Ninja is small and slim but punches above its weight class in terms of usefulness. The tools are all things you might find yourself searching through a drawer for and are useful in a pinch. It fits comfortably in your wallet and will help you open a beer or tighten a screw. The coolest feature that I couldn’t find on most other similar products was the credit card phone stand. It is great for planes and other travel applications (I haven’t had trouble bringing this on a plane anywhere I have traveled, 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. We take it with us when we travel and we always end up using it.” —Andy Aguirre
