Hm,
interesting, but I would like to know, if:
1) these cuffs come from the official manufacture or from any of the unofficial manufacturers which operated in my country in the early 90s
2) it is from some czech show (I recognize the moderator), so I understand well and that man breaking the cuffs says: " it is impossible to rip them off across the chain, but possible to break the lock. It seems that he simply claspes his hands and break the lock owing to increase of matter of his wrists, but:
The two pawls are rotating around pin 3,0 mm thick, it is almost impossible to bend this pin because is only 8,0 mm long and it must be brutal force to bend such a short and thick pin... In addition the pin is made from very strong material.
Try to count a resisting moment of such a pin and it is very high level...
I know the personf from the manufacturer plant, I have a pair of RALK took apart at home and RALK are very strong cuffs, much stronger than Peerless or SW. Peerless has thinner pin. If he breaks them, then he is able to break every cuff.
