This is a slightly different way to pop a combo lock than using a t shaped shim.

Skip to at least 7:00 to get to the "action". The actual opening happens somewhere at the very end.

Yup. Really awful style, but maybe that's what's selling.

This doesn't appear to be one of the Master branded locks, so does it have their gear shaped pawl/locking bar? Curious if this works only on the old style.
