Simply not true, thank goodness. Tests by "Cycling Plus" and "Soldsecure.com" show that no leverage method, prying method, or "hammer" method will work on the best 2006 model locks, such as the OnGuard Brute and the Kryptonite New York lock. Power cutting tools will work, but on the best locks, even power tools will take time.
"Cycling Plus" tested a chain that power tools could not cut, and a padlock that power tools could not cut. They were from different companies, requiring a cyclist to "mix and match" brands. And, their combined weight of eight or ten pounds was far more than most cyclists are willing to lug around.
The best practical solutions are "gold" rated u-locks, listed at Soldsecure.com. They weigh five pounds or less, half the weight of the best chains.
