Spare handcuff keys are thought of by many police officers to be essential. There are a few reasons for this. One is that the standard issue key is very small and it can prove to be unmanageable when contending with struggling suspects. Another reason is that officers find it very useful to have at least one extra placed in a different part of your equipment belt or vest. Again this comes in handy when in a difficult situation: you may be in an enclosed space or the suspect may be giving you a hard time, a cuff key placed in a more easily accessible pocket could make all the difference.

Modern after-market handcuff keys are designed to eliminate all the previous problems. Officers have always been involved in the design process as they use them on a daily basis and often have the most appropriate ideas for new features. A round swivel model has much better grip due to its size. Locking and unlocking of the cuffs is simple and quick. By spinning the swivel handle between your thumb and forefinger you can simply lock and unlock the handcuffs. At 9cm this key can be put into your pocket without you worrying about injury. The steel loop allows for attachment to key rings, equipment belts or vests. Constructed from heat-treated stainless steel giving an indefinite period of service this handcuff is compatible with all Hiatt and Asp handcuffs.

The extra wide, flattened handle of a flat knurl swivel key is perfect for when you need ultimate control with minimal effort and attention. Again a great item for a struggle this one is also constructed from heat treated stainless steel and is compatible with all Hiatt and ASP handcuffs. Two ring attachments, one large and one small, are good for attachment to anything you like.

One example of a multi function model is the ZT version with window punch. The window punch function on this key is a very popular feature within the police force. Officers gaining injuries due to incorrect use of their batons on toughened glass windows has become an increasing problem in many areas. The spring loaded window punch is simple and effective and the key is compatible with all ASP and Hiatt handcuffs. This key features a pocket clip, which also attracts a lot of people.

Another type of handcuff key has a handy pocket clip rather than a loop. This one is constructed from heat-treated stainless steel for an indefinite period of service. The pocket clip design is often used by officers who wear equipment vests as they tend to have a lot of spare pockets to attach it to. This also eliminates the ever increasing risk of leg lacerations being caused due to incorrect storage in a trouser pocket. As with all ZT handcuffs it is compatible with all Hiatt and ASP handcuffs.

Due to its composite construction of stainless steel, for an indefinite period of service, and carbon fibre for lightness, the ZT carbon fibre handcuff key will be attractive because it weighs so little. Don't be fooled into thinking that as the designers have used a lightweight material that they have skipped any other part of the design procedure, or that any compromise has been made to its manufacture. This key is as robust as all other ZT models.
