Krypto - the uncuttable bike lock?!

It's not a good word about the lock, it's just saying that you need the right tool for the job.

Jaws of life are made pretty much with a single use-case in mind: Car bodywork.

You might have noticed the car-bodywork isn't generally solid steel, it's usually an alloy that has a cross-section like a girder... if you flatten it then it loses all it's strength. That's what the jaws of life do, they flatten the structure to remove the structural properties, and then they twist (not cut) the flattened metal and without the strength of the cross-section it breaks easily.

So they're not cutters, and your average bike thief isn't going to be using them.

Your above-average bike thief may use a battery powered angle grinder though... and that is designed for the job of cutting through solid steel. Your Krypto lock would be lucky to last a minute.

Interesting, I knew there must be a rational explanation but couldn't work out what it might be. So the jaws don't break the lock because the shackle doesn't squish. Cheers for the heads-up.
