Hutch, I was just noticing that the picture of the single Schuko socket (with the grounding pin bent up and away) is a South Korean-market socket.
If you look closely at the large size picture, you can see the SK logo (a K inside a stylized S) for the Korean Standards bureau. This is the organization that certifies all the electrical bits and bobs sold on the market there.
Korean devices use American-sized wall boxes for mounting. American sockets are still used there in some places also.
The grounding clips (which in Korean wiring are not connected to anything) in Korean-made Schuko sockets are very thin pieces of spring steel, so they can sometimes get damaged if you're rough when inserting a plug.
I have a couple of sockets like that here at home.
South Korea uses 220 volts with two live legs for domestic electricity (both pins are "hot").
There is no neutral and there is no earth. Obviously polarity is not a concern for the Korean electrician.
