Locks that work

The Brute is advertised as having a 16.8mm shackle. However, while most of it is that width, there is about 3cm at each end (the bits that go into the bar) which taper down to about 13/14mm. Since I foolishly removed the plastic covering from the bar (because it was huge before), these narrow 13mm bits are exposed to bolt cutters, angle grinders etc, making the 16mm part effectively useless.

Would be interested to see a photo to see the amount of gap with the lock locked.
