Vector cuffs are and item form the comic that can be used in the game. to explain more about them here is a question answered by the comic creator.

..Stupid question. What are vector cuffs,and how do they work?Edit

Just like Jigsaw's pouch has a pocket into vector space where she can hide Gangrel (among other things), vector cuffs are a more visible use of the same principle.
Basically, Jigsaw's arms (and Jason's, and Alice's...) are floating off somewhere in vector space. She's not physically restrained so much as they're no longer in physical space, and she can be freed from them just by pulling them off like you would a tight glove. Of course, since her hands are nowhere near the cuffs themselves, she's going to have a little trouble trying to free herself...
