I came across this handy little micrometer

now you can measure the size of that wire or drill bit,
even the thickness of a fag paper.

I've still got my old micrometers too, not that I ever use them these days. And a one-inch calibration disc as well. I do use my verniers though, every now and then; as has already been said, the ability to do inside measurements (as well as depths) makes the vernier more versatile even while it's a tad less robust than a straightforward mike. I do tend to use the digital version more often, if only because it's a damn sight easier to read with varifocals.

I just thought that for the money the less mechanically minded
could measure 'O' rings and stuff.
The steel digital Verniers are obviously more useful (small 'G' cramps?)
I three plus micrometers, I even had bore micrometers (until I gave them back)
