A chinese "SOLID extra plus top security" ™Abloy style disc-detainer padlock (THANKS REDBIRD1983 FOR THE LOCK and the encouragement =) picked with a dedicated tool from: www.uklockpickers.co.uk this lock contains 7 functional discs,and one driver disc for a total of eight. picking disc-detainer locks a is an absolute rush,but there is a learning curve,and if you want to try this ,pin-tumbler picking experience is a great asset. this type of picking takes a lot of manual dexterity and sensitivity. i am hoping to got more of these type locks,and picking abloy is my ultimate goal!
