Armored cable locks seem to be just cable locks with metal covering? It seems the metal is in pieces (so that the cable can bend).
The tube sections are supposed to be tool-resistant steel, and there's not enough slack in the cable to spread the tube sections and expose the cable itself.
How secure is armored cable lock? Can they be broken by tough bolt cutters? Anyone heard of such locks being broken?
Yes, yes and yes.
But then again, any lock can be broken--given enough time and nobody around.
