Re: Only cracking I have done is
When I was younger I did the same with padlocks. The cheaper ones I remember could be opened by just turning one way almost 360 degrees then the other way the same before going back to a final stopping position. Before TSA locks came in I opened the padlock on a friends case when they forgot the code. Betting me £100 I couldn't do it in under a minute was a mistake. You just had to put tension on the lock and turn the dials.
