It takes roughly 30-45 seconds to cut through a U lock with a cordless angle grinder.
It takes roughly 5-8 minutes to cut through a hardened, shrouded shackle padlock that is well made.
That buys a lot of time. To a thief, more time than they want to spend (usually).

Granted, they will just cut your cable before the padlock. A hardened hex chain is way more difficult to cut through than a cable. It is hard to hold it taut while you try to cut through. That being said, we are talking about a SECONDARY lock, say, for your wheels. You should also have a U lock through the frame somewhere.

MOST thieves will just move on when they see a bike locked up in this way.

If you don't think a HEAVY DUTY padlock is worth the expense, don't buy one.
You keep getting caught up on the restricted key system, and how useless it is. I recommend these padlocks for those looking for the BEST PADLOCKS made. High quality. Made with hardened materials and cylinder protection. The key restriction is just a bonus, and I recommended it, mainly, to a customer who already had MTL keys on his condo. Key the padlock to his key, and BAM, carry one key.


You have a nice day too. It is really warm and sunny today, let's get out and ride.........
