He was able to open handcuffs built by the German firm Bonowi and the English manufacturer Chubb who both use a single key design for their products. Although the keys are purportedly harder to come by than more standard cuffs &amp; not commercially available, Ray says he bought a Chubb key from eBay, and obtained the rarer Bonowi key through an unnamed source. He reverse engineered the keys &amp; built CAD models that he then cut in plexiglass with a laser cutter and printed in ABS plastic with a Repman 3D printer.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.shapeways.com\/blog\/wp-content\/uploads\/2012\/07\/Screen-Shot-2012-07-14-at-6.14.45-PM.png\" style=\"font-size: small; color: #000000; font-family: arial; margin: 0px; \"><\/p>\n<p>Ray, says his goal isn&#8217;<span style=\"color: #000000; font-family: arial; font-size: small; \">t to reduce security but to expose the vulnerability.
