These tiny adapters allow greater flexibility of use for Lishi brand 2-in-1 style decoder lockpick tools. Lishi picks are made in different lengths for different sizes of lock. However, due to their high cost, Deviant thought it would be a good idea to help people adapt larger sized Lishi tools so that they work effectively in smaller locks, obviating the need to purchase additional expensive hardware.
This small collar fits over the blade of a Lishi pick to provide 0.153" of standoff distance from the front face of the plug, which makes it suitable for use on both Schlage and Kwikset style systems.
