Correct me if I’m wrong, but these manacles are Dragonsteel, right?
I think it would be very difficult to trick the manacles into being removed.
Besides brute force overpowering their mechanism, there’s essentially no way to break Dragonsteel.
Dragonsteel Prime spoilers:
Dragonsteel and associated MoIs will be changed from the novel
All this to say that dragonsteel without any added mechanism is scaaary. Really. Scary. It’s to the point that some people thought it was a GMetal for a time.
With the combined knowledge of all dragons (possible because of dragon magic…), they devised a way to make it as impenetrable as possible. They’d definitely have put in a way to offset the cutting of the arms.
