Sorry but you are wrong I have both a Metric & an Imperial set
I put conventional nuts on all 4 of my brake blocks yesterday.

I think @silva lives in the continent. You need to go to specialist tool shops to get imperial tools in there.

Although I dislike Pozidrive screws & bolts, I know I have to put up with them,so I buy J.I.S. pozidrivers, at least they last.
J.I.S. (Japanese Industry Standard) is a different shape to both Pozidrive & Phillips, though they are closer to Phillips just the tip is a bit shorter (less pointy).

You beat me to it. One of my (relatively) recent buys was a set of JIS screwdrivers. Quite a few bits of far east kit needs these otherwise you munge up the screws. I'd previously, and wrongly, though Philips heads were poor, but now realise I was using the wrong screwdrivers on some of them, having only recently discovered the need for a 3rd set of drivers.
Three different, and not truly compatible, sets of identically sized and very similarly looking fixings. At least two engineering committees deserved a kick up the backside for that. I believe there are yet further variations beyond that too

There is another standard as well which is predominantly used in Canada there's a YouTube video which I found sadly very interesting which I'll try to find again

That’s the Robertson screw, which has a square shaped socket in the head. I seem to have picked up a set of bits somewhere along the way, but have yet to encounter one of the screws. Apparently popular for wood screws in Canada. I notice Torx becoming increasingly common on wood screws in the UK, presumably because they’re good for power driving.
Bought a set of Robertson screws & drivers a couple of years back and for general applications, it's a no brainer. The screw stays on the driver at any angle and it's very difficult to torque the screw out, which is what the Roberston screw system was designed for; as boat & plane builders were fed up with employees overtightening the Phillips screw and damaging the thin ply / alu sheets when the driver slipped.
Check out The History Guy on YouTube; it's all there - !

Apparently, Mr. Robertson was a bit of a stubborn individual, otherwise Henry Ford would have adopted the Roberton screw system for his production lines as oppose to the Philips screw.
Pity really.
I can imagine Mr Ford being very easy to do a deal with

Quite - here are a couple of imperial sets. I have a fold up set in a handle somewhere as, and several different metric sets with various configurations too

I too have a set containing metric and imperial hex keys. By some miracle I've managed to keep them all together without losing any (well ... maybe some of the diddy ones) and without getting them mixed up. It's most uncharacteristic of me. Not getting them mixed up is made easier by the fact that I've never had cause to use the imperial ones.

My lathe, which sadly I no longer have, needed the purchase of the heavy duty Eklind set above. I confirmed it was genuinely good kit as I had to shorten one of the keys above for access to a particular screw. A hacksaw wouldn't even scratch it and needed the angle grinder to trim the end off. I've never believed in buying cheap tools !
