The Steel-O-Flex from Abus is a highly flexible and highly attack resistant choice of lock. Unlike other cable locks, the steel cable is covered with overlapping toughened steel shells giving a similar effect to scale armour. Any attempts to break open the lock result in the lock's increased resistance against hitting, pulling and picking. The lock itself also features an automatic keyhole cover to protect against dirt and corrosion and it is supplied complete with a code card and an LED lit key.
