Well, for some one who has literally gb's worth of lock photos, I decided to add one here. This is the winkhaus vs5 lock. Can you figure out why the actual face of the lock is recessed? I'll elaborate later in the post
First, this lock COULD be deemed as bump proof in the same category as schlage primus, scorpion CX5, etc that use a secondary locking system whether sidebar or inactive pins. IF you mill the profiles from the side of the key you eliminate this protection. IF you order from OUTSIDE your region online which is more feasible these days you can have a lock that is fairly secure for a minimal investment due to the sheer numbers of keyways available for this lock outside of the side profiles.
A pic of the plug face:
See how the inactive pins protrude into this area if the wrong profile key is inserted into the keyway. These passive locking pins are installed on both sides of the cylinder/plug:
A picture of a common top pin stack. You can see 2 standard pins and 2 inverted spools with 1 normal spool pin.
Here you can see all 8 passive profile pins in the lock sets. 4 passive pins are intalled in each side of the cylinder (Typical).

Pics of each side of the keys. Note the dimples on each side of the key blank:
Finally is a couple pics of the keyway:
Now, onto the recessed face of the lock. It is not only for asthetics, but for key strength. A very very small amount of key bending will transfer the turning force to the face of the plug and not the key blank itself. This greatly reduces the amount of broken keys you will see. A great idea on a neat lock
