Pen knives are cool because they ensure you are ready for pretty much anything. Door a bit loose? No problem, just pull out your screw driver! Label need cutting out of clothes? Tiny knife to the rescue! It makes you feel self-reliant and is pretty much the closest you can come to being like Doctor Who having your own Sonic Screwdriver.
But sometimes being ready for ‘pretty much anything’ isn’t enough. Sometimes you need to be ready for ‘literally anything that can possibly happen’. For those situations, the Wallet Ninja is the perfect supplement to your pen knife.
The Wallet Ninja is sadly not a tiny ninja that lives in your wallet (Indian in the Cupboard style) but is still pretty cool. It’s the size of a credit card and provides tools in the form of cut out notches and indentations. Ultimately, it does the job of way more tools than you would think possible with something of its stature and that includes screwdrivers, bottle openers, hex wrenches, letter openers, phone stands, peelers and more.
Presumably you can also throw it, shuriken style, at attackers. But then again, you can also do that with literally everything you own (things you’re not too attached to at least…).
