Frequently Asked Questions
1. How did handcuffs evolve over time in the Western world?
Handcuffs have a long history, with references to cuff-like devices dating back to the Fourth Century BC. The Hiatt Handcuff company, founded in 1780, was the first major manufacturer of handcuffs. In the 1850s, the use of handcuffs became more widespread as crime rates increased and the population grew. Before 1850, there were two main types of handcuffs in use in England: one that restricted movement and was commonly used on violent prisoners, and a more flexible type that allowed prisoners some movement for eating and personal necessities. The flexible handcuffs, also known as the “Darby” or “English” handcuffs, became popular for street use due to their easy concealment.
2. What is the innovative design behind the “Peerless Swingthrough” handcuff?
The “Peerless Swingthrough” handcuff, invented in 1912, revolutionized handcuff technology. It featured a swinging bow ratchet and adjustable handcuff design, allowing for easier engagement and more effective restraining of individuals. This design addressed the limitations of previous handcuffs, which were heavy and difficult to use on violent prisoners.
3. Can handcuffs be picked easily?
Handcuffs can indeed be picked easily with the right skills and tools. For example, a bobby pin can be used to manipulate the lock and bypass the handcuff’s mechanism. This highlights a fundamental problem with the lock design, as even a simple skill like lock picking can enable someone to break out of handcuffs.
4. Are law enforcement-grade handcuffs easily accessible to the general public?
Yes, law enforcement-grade handcuffs are readily available for purchase by anyone, which raises concerns about their accessibility and potential misuse. These handcuffs can be acquired from various sources, such as surplus stores or online retailers. The easy availability of handcuffs increases the risk of them falling into the wrong hands.
5. Why haven’t there been any updates to the design of handcuffs since 1912?
The current design of handcuffs has not been updated since 1912, despite concerns about their effectiveness in keeping officers safe. Changing the locking mechanism on handcuffs would require every officer to switch to new keys, which may be a logistical challenge. This could be a reason why no significant changes have been made to the design, and the technology remains deprecated.
6. What skills are necessary to pick handcuffs?
Picking handcuffs requires knowledge of the lock’s mechanics and some basic lockpicking skills. The key must be inserted correctly and turned in the direction of the cuff’s travel to release the single lock. The double lock is engaged using a pin-like key, which needs to be inserted into a horizontal slit in the cuff and pressed away from the cuff’s direction of travel. To pick handcuffs, a bobby pin needs to be prepped by bending it into a 90-degree angle. The bobby pin is then inserted into the lock and manipulated to release it and free oneself. These oddball skills can be learned from a comprehensive guide or obtained through training in lockpicking techniques.
