    Default Bramah challenge padlock

    While in the Science Museum in London I took this picture of the Bramah Challenge padlock. The lock originally had 18 slides and a single spring, however after it was picked by Hobbs it was converted to 13 steel, false notched slides each independantly sprung. In it's current form I am quite sure Hobbs would not have been able to defeat it.

    I believe Hobbs, being the perfectionist he was, would have been able to defeat the newer improved model also LOL
    He was a fanatic and once challenged wouldn't give up until he defeated the new safeguards.

    He tried and failed to defeat the cotterill design, (top of the range version). So I'm not so sure.

    You could be correct?
    Some Intelligence agencies have found how to
    defeat high security locking mechanisms
    and don't reveal it.
    Then everyone believes they are undefeatable
    and use the locks to protect sensitive material.

    Didn't Hobbs cheat with the Bramah lock anyway? drilling a hole to take off the spring pressure from the sliders and then disguising the drilled hole?

    The contemporary accounts certain infer that the lock was mucked around with and not in the best internal condition afterwards. The slides of the time where made by iron and it is suggested that hobbs had bent these to keep them in place once picked. When rebuilt steel slides, very heavily false notched were fitted, each with it's own spring.
