This thread fascinates me. My
crap X-Man power super-power is spotting left-handed people.
In carpentry I'm quite ambidextrous for planing, filing, sanding or feeding machinery. But one thing I can't master is sawing as it has placement and motion in 3 axes. Hard to coordinate them all at once plus keep the sawing straight.
I apply the same logic to eating - I'm sawing food with the knife, fork hand is more flexible. So it's right handed, right hand knife, and if just fork/spoon, right hand. TBF I went to school late and was mocked for using the wrong hands and switched to the conventional way. Table manners generally make me nervous.
Back to the other things... I spot lefties because I'm a guitar tech and left-handed guitar players look WEIRD. So I usually see lefties a mile off due to little clues like writing on the back of the right hand. Pointless
I do think the internet generation of men has a few more... Switch-handers... due to the nature of right hand being busy with mouse... Brief research confirms it.
