As I was browsing through Men’s Journal magazine I noticed this crazy little invention. It is a key that is slightly larger than your house key and acts as a secret pocket knife. You can put it on your key ring (which is way handier than keeping up with it in your pocket if you ask me) and always have it for whatever you guys need a pocket knife for. Even those this was slightly alarming to me, you can also get it through airport security. So for those of you who love to have a pocket knife handy for, you know, whatever….here’s YOUR gadget.
