Sorry but you are wrong I have both a Metric & an Imperial setThe keys were sold and marked as metric, they never sell other than metric anyway.

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).
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
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 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.
