The Schlage SC4 lock pick REVERSE HANDELING
Lishi tools help you landmark directly under the pins and also show you the possible pin heights at each location.
This then lets you apply tension at exactly the "possible" position where the pins would be at the sheer line.
Its a road map of the ALL the possible routes inside the lock.
It also lists the cuts so as you pick if you take notes of when the pins set you will know the cuts of the key so one could be reproduced.
This Lishi variant fits in the Schlage (5 Pin) keyway commonly found on locks made by Schlage and several other companies.
