I saved a lot of headaches by just getting a set of digital calipers with a solar panel so I never have to worry about the battery. I really wish someone made

  >I really wish someone made a set of micro-vernier calipers that are small enough to fit on a keychain. I'd really like to know what you mean by that. Obviously the Vernier scale can't shrink, so you're going to be limited to an inch or two of range, and all the sharp edges common to calipers aren't pocket friendly. Something fold-up, or that has a few pieces to snap together?

    Two inches of range would be perfect for sizing bits, fasteners, bolts, screws, etc. I tried carrying a messograf pen for a while but they're wildly overbuilt and heavy. Amazon, eBay etc sell a caliper keychain but the tolerances are too loose for it to be useful and it has no vernier scale.
