This set of 6 standard practice locks is designed to take a beginning or intermediate lock picking student through a series of mounting picking challanges, culminating in a 6-pinned lock with a difficult combination and spool drivers. The first three lock cylinders are pinned 3-, 5- and 6-pinned respectively. The second set consists of similarly pinned locks (though the combinations are NOT identical to the first set), and these feature spool drivers to make the challange even greater. Available in either KW or SC keyway.
