If you’ve ever spent any amount of time handcuffed, you know how uncomfortable it can get—even if you were originally put in that situation by choice. TIHK HK2—as in, Tiny Inconspicuous Handcuff Key—is exactly what the name describes, a small, universal key designed to unlock most handcuffs. It’s made of an incredibly lightweight toughened polymer that’s durable enough to do its job while barely tipping the scale at 0.01 ounces. With built in teeth and an integrated clip, the TIHK HK2 Handcuff Keys attach to the back of your belt or pants easily to allow you to access it if you’re handcuffed behind your back, and the Jean Blue, Light Khaki and Dark Gray color options keep it from being detected in most circumstances. We’re not saying you should go out and do something stupid so you can test it—they have practice kits for that—but if you find yourself in a situation involving handcuffs that you need to get out, the TIHK can help.
