Have You Ever Seen a Lock Like This?

Bosnian Bill has found a lock he cannot pick. Just wait until you see why not! This clever mechanism works in a different way from most locks, as it’s not straight. It’s a rare, complicated, and presumably expensive lock for which most locksmiths could not duplicate a key. Lose or break your key, and the whole thing would be rather useless. I'd never let any of my kids near that key. (via reddit)
