At least the UK one is blunt. I’m trying, without success, to find a picture of the old style telephone (and my modem) connectors we had here in Norway. Imagine the UK power plug, but the pins are pointy. I’ve drawn blood stepping on these. I would run a marathon on Lego to avoid stepping on one of those again. Luckily they were gradually replaced by wallmounted RJ11 (or RJ45 if you had ISDN) during the 90’s.
