I recently picked up a new hobby: locksport http://en.wikipedia.org/wiki/Locksport). Locks are something that we all use everyday but very few people understand the mechanics and the inner working of the lock. So I decided to study its different mechanism, its different designs and especially the art and challenge of lock picking.

The first rule of locksport is: "You may only pick locks that you own, or those to which you’ve been given expressed permission to pick by the rightful owner"
