The pawl is the big part labeled 22, and teeth of the pawl are labeled 25. The image below, from a 2002 patent for a handcuff locking mechanism, shows the shackle (17) and its ratchet (20). The part known as the “key way” is the lock itself-the hole where you insert the key to unlock the cuff. The part of a handcuff that swings is called the shackle, and is equipped with a ratchet, or row of teeth, that interlocks with a row of teeth on the “pawl,” a part inside the thick bit of the cuff where the shackle is inserted. We approached Schuyler Towne, competitive lock picker and Security Anthropologist at the Ronin Institute, for his advice.īefore we get into the details of breaking free, it’s essential to establish the terminology we’ll be dealing with. But if you find yourself in this scenario, and would like to be released from your shackles, there are a few ways to go about it. We won’t ask any questions about how you got there.

Let’s say that, once restrained, you decide that the whole being handcuffed thing is not so appealing, but you don’t have easy access to the key that will bring you freedom.
