This is the baby from Blackburn's Local series of U-Locks; the Compact. The U-Locks are simple but well thought out pieces of user friendly engineering, designed to deter thieves simply by sheer intimidation. Each one has a hexagonal shackle shape, which prevents the shackle from spinning, effectively doubling its resistance to cutting or leverage attacks. They're also bump and pick-proof, and to cap it off are coated with a soft silicone sheath to protect your frame from nasty scratches.
. Twist proof hexagonal shackle deters thieves by roughly doubling the time to cut away your lock
. 10mm thick hardened steel shackle wrapped in a silicone sheath keeps your bike protected from thieves, and safe from scratches
