Apologies for the rambling, after trying to get this on camera for several days I was so excited I had forgotten my prepared remarks.
Another Abus 83 series padlock, this time the SFIC (Small Format Interchangeable Core) version fitted with a BEST core. Despite the fact that SFICs usually do not have security pins they are very difficult to pick. Interchangeable core locks have a minimum of two shearlines but, unlike in a master keyed lock these shearlines are not interchangeable, one operates the lock as the normal user's key would while the other allows the core to be removed from the housing. Both of these shearlines can be mastered in particularly large sytems. If the lock can be picked to the Control shearline (which allows the core to be removed) the lock can usually still be opened by using a screwdriver or other tool to operate the tailpiece or cam inside the lock housing.

The locks in this video use the BEST SFIC A keyway, like many IC keyways, it is wide enough to comfortably fit even very thick tension tools but the shape of the keyway forces you to use very thin picks. A maximum of 0.018 inches thickness is recommended.
