What type of action would it be to bind someone with them?
Could you apply them in a grapple, by either 1)with a grapple check using the same mechanics as Tie Up resulting in them being bound by the shackles instead of being tied up and helpless, or 2) by not using a grapple check and instead using an action that doesn't require two hands? Would the check be your CMB vs. your opponent's CMD or would it be some other sort of attack roll? Is there a more esoteric method I have not mentioned?
Can you bind one of the shackles to your opponent and one to yourself - both becoming bound by the shackles?
Can you bind one of the shackles to your opponent and one to an inanimate object?
