Restraining people is fun! but make sure that the restraint device or your grip is not too tight and avoid joints. For example, if you put someone’s arm behind your back, grab the lower part of their forearm instead of their wrist. Do not restrain someone by the neck.
Also, make sure that you can untie the restraints through practice or have flat bandage scissors on hand for rope play to release them quickly.

To unlock standard handcuffs, simply Insert the handcuff key and turn it counter-clockwise, as this disengages the double locking bar or you can use a paperclip, bobby pin or other metal object to act like a key by bending it a similar length to a standard handcuff key. An easy method to use a paperclip is by opening the clip, sticking one end all the way into the lock, and bending it long ways to make a short-looking L.
