These stainless steel handcuffs feature a double lock mechanism for convenient and secure use. In single locked mode, the handcuffs can pass all the way through the ratchet until the teeth are free on the other side. This allows quick unlocking of the handcuffs in an emergency situation. To put them in double lock mode, a pin can be pushed down with the key and the handcuffs will no longer be able to pass all the way through the ratchet. The cuffs are linked with two chains which creates a hinge. Constructed from stainless steel which feels solid and weighty in your hand. Unfortunately, going around performing citizen's arrest may not be the best idea. You can however, use this pair of handcuffs as a prop, part of a costume or reenactments. Each pair comes with two keys in case you misplace one during your adventures.
