This one goes into “Not Safe for Whaaaat?” category. If you ever end up getting handcuffed by…uhm…evil kidnappers or when you are unlawfully detained  then this is your way to freedom. It is easily attachable to your clothing so it will be ready when you need it. It features a minimal, low-profile design and low-visibility coating so it will go undetected when detained. I mean, who expects you to carry a spare handcuff key when they cuff you, right? For law enforcement, military, and security professionals this may include being restrained with their own cuffs, captured person release and evading capture themselves.
