Core Shims
Core shims are designed to attack locks that do not have a protective collar between the core and the lock body. This is a surprisingly common feature on Lower and some mid security locks.
The attack is simple wedge the shim over the core and slide it back until it stops. The object that is stopping it is the top pin of the first

Sturdy, well made, curved shims that fit perfectly between a follower and the core of locks you are gutting.
