The reason this is annoying is that there are other measuring devices that can have a vernier scale though. For example, in my shop I have a cheap micrometer that only measures to thousandths of an inch, and a more expensive one with a vernier scale that measures to ten-thousandths. Offhand, height gauges also commonly have a vernier scale. The reason this is annoying in a shop environment is that there are likely other tools around with a vernier scale. That being said, I've also been around older machinists & engineers who exclusively refer to gauge blocks as "jo blocks", even when there wasn't a single set manufactured by the Johansson company in the building. This is common enough that searching for "jo blocks" returns a dedicated page on mc-master: https://www.mcmaster.com/products/jo-blocks |
