Digging through my old tool box I came across a boring bar I had made for some project at work. I have no idea what it was for and even if I used it on the lathe or the Jig borer but it was for small holes.
Now I could not even begin to grind a tool like that.

Impressive!
 
It is a turning tool.
I worked in the Special purpose machine department at the Plessey company in England. We made some interesting stuff. Some parts had to be made to Tool Making tolerances and this was before the days f the digital readout. It was all read the dials.

AFAIC the digital readout stuff is fine as a clock. Not for precision measurement. I'll keep my analog micrometers and dial indicators. No battery required.
 
I use digital calipers almost every day. Push a button and you get metric. Half of the machines at work are metric and half are not. Makes me nuts.
Now, if I need "real" accuracy I use analog tools. But I rarly need anything that close. But for everyday, I love the new digital stuff.
 
I tend to do the same when making measurements. I can get a reliable measurement with my 50+ year old Starrett micrometer but use the digital calipers for most work.
I do need a Digital readout for my 3 in 1 machine as the dials are a bit odd/not reliable.
