I the shop, we use a couple of Starrett as well as old Bridge Tool Works from 20 years ago. I use it when I am in the shop working but my guys know not to touch them. They make a fine tool, contact Rutger, RWest here. He's involved with them. In the field, we use old Stanly #1 squares I b ought 20 of them 20 years ago, for precision work and my guys know better to take care of them. For anything else, they buy their own junk.
Oh, I hate adj squares or combination sq.
