- wdewind 16y agoI looked at masterlock's "patent pending bump resistant technology," that one of their locksmiths called "an elegant piece of engineering." It looks to me like they just put a tougher spring behind the cylinders so the bump doesn't have enough energy to force the cylinder up. Can anyone explain if there is something more interesting going on with bump resistance? edit: (this is the video linked below - http://www.youtube.com/watch?v=kUJWc7rIj8I&feature=related http://www.youtube.com/watch?v=kUJWc7rIj8I&feature=relat... - didn't realize)
