From what I can tell, it ejects the claws when your arm tenses to a certain degree. For example, you can make a loose fist and they won't come out, but make a tight one, and they will.

Oh, yeah, that makes sense. Seems silly though. With as much as you need to flex your hand, it seems like you could just put some sort of trigger somewhere on your palm or something.
