Lock picking is almost as much an art as it is a science. You can read all the lock picking instructions and still not be able to open a single lock. The skill of lock picking involves gaining a good feel for the lock mechanism and the lock picking technique needed to open it. This requires practice and concentration. The number and variety of locks in current use is staggering, yet the vast majority of locks in use are simple pin-tumbler designs. Common lock types include: * Pin-tumbler locks * Warded locks * Wafer locks * Lever locks * Dial combination locks * Disc combination locks * Push-button combination locks
