Abstract : Police and Security Officers within the United States as well as other countries typically use a standard type of handcuff key when detaining, releasing, transporting or arresting suspects. This can create difficult problems when using standard handcuffs or other restraining devices with standard issue keys. Aftermarket keys come in various designs and are indeed of assistance when compared to using the standard issue keys which typically come supplied with the purchase of handcuffs. Officers must often struggle with these small keys in hazardous situations which can lead to injury or even escape of detainees. The badges of certain police departments and security forces, whether worn in uniform or carried on a badge holder by plainclothesmen, carry a feature which enables the use of a unique, specific type of handcuff key. It is much easier to use, remaining concealed and secure until needed, yet readily accessible for use.
