Frequently Asked Questions (FAQ):
Not on this planet. We are asked that a lot, but modern metal cutting devices: bolt cutters, portable grinders, burning torches, etc, can cut through all metals. Some are harder to cut than others, and some are very noisy to cut. A good heavy duty padlock will usually be a good enough deterrent, and the equipment that a would-be-thief would need to cut through some of these padlocks would wake the entire neighborhood! For our highest security padlocks, look at Master Lock's 40KADPF, 6230KA, 6321KA, 7035KA, and the hasp-less 6270.
