German hacker Ray has shown that he can print working Dutch police handcuff keys from plastic on his 3D printers, and has released the 3D files so you can print your own:
He used a 3D printer to print handcuff keys. And not just any ordinary handcuff key … no, it's the official handcuff key from the Dutch police! At first the police officers at HAR were a little reluctant to event try out the plastic key he printed. But he found another way to verify the key he printed was the correct one. I guess these officers never thought about wearing keys concealed, especially when talking with Mr. Handcuff himself. Given the megapixel camera's on the market today it was not so difficult to verify the key he printed was the correct one.At the end of the day he talked the officers into trying the key on their handcuffs and … it did work! At least the Dutch Police now knows there is a plastic key on the market that will open their handcuffs. A plastic key undetectable by metal detectors….
Printing police handcuff keys …
