"when I had to work on a lot of kit in awkward confined spaces"
Same here. Working on cars or DIY both require the appropriate hand to fiddle with things. It is interesting watching people swap things between their hands when they could just as easily use their non-dominant hand to do something.
Apparently the non-dominant hand is only about 10% inferior - but most people don't exercise it enough to minimise the difference.
My left is good at doing fine things - but not at rhythmic ones like using a saw or hammer.
As the saying goes - "I'd give my right arm to be ambidextrous".
Biting the hand that feeds IT
