Locks that work

heh, I wonder if it could be repaired with gaffer tape ._.

Nice how they don't bother to mention how long it took to break through the Fahg Mini or Abus 54 so we can compare it...

A Bikeradar review of it is online, only a few days old... "The Strongman stood up to the first of our usual lock tests, a five-minute attack with standard tools, and in the subsequent power tool test the shackle took just over 30 seconds to cut through, and that was after a minute or so of cutting away the silicone cover. It all adds up to an impressive little lock." Doesn't seem too bad to me. I'm guessing it could be cut with 1000mm bolt cutters just about? Seems like it should at least make it onto the secondary locks thread.

But a round shackle has a smaller cross sectional area than a square one. So 13mm square Abus is like 16mm Kryptonite. I don't see TiGr in either of the links you posted :S

The TiGr is in the full review in June 2012 men's journal page {{edit here:- http://www.mensjournal.com/expert-advice/torture-test-bike-locks-20120925 }} - Apparently, they were able to hacksaw through it as well, and they can't even have been using a carbide blade, as it didn't touch any of the hardened locks.

I think the knog has a round shackle under all that silicon - I seem to recall seeing a review where they cut the silicon off and cut it with bolt cutters. It looks like it might be ok as a secondary lock, although overpriced. There's video review of a few 13mm locks here:- http://gizmodo.com/5922074/the-best-bike-lock again they're not using the best choice of blades, discs or croppers.
