I have Starrett, Brown & Sharpe, & a few Mitutoyo precision measuring tools that I inherited from my father after he inherited them from my grandfather and they are still right on. When my kids see them they ask me what are these things for?? even after I have told them many times in the past! My grandkids don't even look at them. Too bad you can't use smartphones for precision measurement. The industry would go on and on and on . . . I hear you guys loud and clear.
