Mitutoyo 500-196-32 Digital Caliper

OK, not everyone has a use for one of these things, but it falls into my - use it a few times a week - category. That's enough for graduating to BOCO status. What do I use it for? Measuring all sort of bolts and stuff, bike parts, pipes, string height on guitars, whatever. The technical term is a "Vernier caliper". I call it awesome, and if I am using it more than once a week...for life...it makes the list.

Get the the Mitutoyo one. Japanese precision. There is no substitute. You can pay 10 bucks or you can get the best...for life.
