There is a simple and quick method to break just about any steel lock. 
It is quite common in Germany where new U-locks have been designed by 
ABUS to prevent this method from working. the method (which I won't 
describe in detail) involves taking advantage of steel's ductile to 
brittle transition with respect to ambient thermal energy. QUESTION: Are 
kryptonite locks protected from this method? And, why is this method 
never mentioned on the backs of the lock packaging (unlike the jack and 
the pipe methods that everyone knows about) if the locks ARE resistant to 
this kind of attack.

Since this method is really easy (and accessible to people near 
laboratories and universities) and since it works on padlocks too, I advise 
the people who use only chains with a padlock to consider using a U-lock 
as well.
