Can be cut with 24" bolt cutters and also a hacksaw according to the review I posted previously :- http://www.mensjournal.com/expert-advice/torture-test-bike-locks-20120925
That review raises some interesting points:
the knog strongman might be better designed than it seems if the silicone actually helps prevent angle grinder attack
the blackburn san quentin is an 18mm lock that needs both sides cut and (from the looks of things) pretty attractive available at http://www.kenfosterscyclelogic.co.uk/m2b0s280p495/BLACKBURN-San-Quentin-2012 for £50, or 70 at all terrain cycles [Is this a competitor to the Fagh/M18 I wonder]
Their website also shows a 16mm lock so NYL level
