最新的发明之一提出了有关安全性的问题，以及是否应更多地关注与其相关的技术和法规。根据福布斯report high-end security handcuffs were successfully defeated by a cheaply produced plastic key using a 3D printer and a laser cutter.
在纽约地球地球会议研讨会上的黑客中，一名名为“雷”的德国黑客证明了手铐。他曾在手铐技术上咨询德国警察，并表示他的演讲目的不是鼓励罪犯，而是向当局和手铐制造商指出安全问题。创建此类钥匙的工具已经适用于犯罪分子和更广泛的公众。
3D打印的复制键是由德国制造商Bonowi和英国制造商Chubb生产的。根据雷（Ray）的说法，他对他在eBay上购买的钥匙进行了准确的测量。然后使用有机玻璃和ABS塑料创建钥匙的CAD模型。
If the handcuff locks were unique, they couldn’t be replicated and opened with any copy of a standard key that matches the different manufacturer cuffs. As Ray stated: “Until every handcuff has a different key, they can be copied.”
