We're traveling to Iceland next month and I've read we need a Type F (a.k.a. Shunko) adapter. As I was looking at reviews and reading up on the type of adapter needed, one person said that these should have half of the tip covered with insulation, like these:

This is the only type F adapter I see on Amazon that has this feature. They say it's for safety, which I don't really get since you shouldn't be touching the prongs as you plug in anything anyway. Anyone know anything about this? Why do 99% of the Type F adapters no have this insulation, but this one does?
Thanks,
Andy
