While at it, are the holes in each flat pin , for anti-tugging latch

That's to make it easier to connect solid wire from the outlet box
directly to the plugs when you're too cheap to buy a new receptacle.

IIRC,a new receptacle costs less than $1 at Wal-Mart.

BTW,I've seen a lot of US power plugs with ground pins that are folded
sheet brass that has the half-round/half-square,or U-shape cross-
section,with a bevel at the end. Maybe cheaper to make than a solid round
pin?

the holes in the flat blades are probably a leftover originally intended
for some sort of detent (ball detent?)to help retain the plug.

I should have said I am in the UK
Now you say that I've seen a plug with a U channel ground pin ,somewhere
along the way. I could see that arrangement maybe giving some sort of
sprung/ tolerating fit. But how does a cylindrical brass pin make good
contact with an unsprung receptacle pin ?
