Heyo, got this from Mad Micks link on the Ingersoll 'Impregnable'

Although these are essentially conventional pin-tumbler locks (based on the
Yale lock of the mid 1800s), they incorporate some serious security features.
These include very severe keyway warding that makes the insertion of normal
lockpicks very difficult; hardened inserts in plug and cylinder body,
mushroom drivers; and up to 7 pins. Access control is achieved using high
precision multiple side wards.
The DOM S 5-pin profile cylinder, for example, uses torpedo-shaped (tapered)
anti-picking lower pins as well as stacked-disc spool drivers. These drivers
consist of a casing pin that houses 4 independent discs. Each of these can
jam across the shear line in the same way as an ordinary spool driver. There
are a total of 1024 profile variations on the keyway, allowing a very high
level of mastering and access control.
...I know this is little info, but hey, maybe it helps.

Never underestimate the half-diamond.
