Picking handcuffs with laser cut keys

At this year’s HOPE conference, German competitive lockpicker and security researcher [Ray] gave a talk about escaping high security handcuffs that are probably being used by your local police and other LEOs. He’s doing this with 3D printed and laser cut keys because, you know, security through obscurity never works.

Two years ago, [Ray] gave a talk at HOPE on 3D printing Dutch handcuff keys (you can listen to his conference as an .MP3 here). This time around, [Ray] copied the keys of Bonowi and Chubb handcuffs, very popular brands for American police. After obtaining a key from each of the two brands, [Ray] broke out the calipers and micrometer and designed his own versions that can be printed on a RepRap or Makerbot, or just laser cut from a piece of plastic; the perfect material for sneaking one through a metal detector.

The .DXF and .STL files for the handcuff keys will be available on Thingiverse shortly. We’d suggest watching this Thingiverse account (nevermind), as they have the files for [Ray]’s earlier Dutch handcuff key.
