Sorta, the idea is you tie knots in it at regular intervals and then you stretch the string across the item to be measured.
A reading of , say, 12 knots is not, however, to be confused with Nautical speed.
Thinking of that shouldn't the marine term be nauts instead of knots?
Here's a Lufkin #199 Universal Test Indicator. It's the ultimate in simplicity and ruggedness. I have an older one that I use, this one's brand new and for show only.
Here is Lufkin's version of the automatic center punch. The Starrett equivalent actually has a better feel and is slightly more compact.
This is a Lufkin inside micrometer set. It'll measure I.D's from 1" to 12". It's easier to use on larger diameters than small ones.
Lufkin made some very nice dial test indicators and this is one of them. It's incredibly compact and the long stylus makes it easy to reach into tight spaces. I bought this one new when I started college.
This is a planer gage that I made in college. It would be really handy for setting the tool height on a planer if only I had one. It doesn't get out much.
Time to throw in a ringer, litterally. This is a Oslund Tool and Die Universal Indicator. This is where the ringer comes in The needle circles that arced section. It is plunger operated and reads 0-10 thousandths.

You'll likely never see another one of these either. It's a Starrett caliper, but one that has no catalog number on it as all others do. I've never seen another, and it's the best caliper I've ever owned. If fact, I sold off a bunch I'll never use because of the way this one works.
It's a double-jointed, double-ended inside or outside, dividers or hermaphrodite caliper, whatever you need it to be.

Those are some handy calipers Ken, I may have to make a set.
Here are a few more high tech tools to add to the list:
This is a Titan toolmaker's micropscope, for when it absolutely needs to be on center. It superimposes a graduated scale on the workpiece and will read directly on the X and Y axis to .0005" and you can interpolate even closer.
This is a Mitutoyo Dial Bore Gauge that reads bore diameters directly to .0001". I bought it for a job and haven't used it since.

These are my sine bars. The big one is a Brown & Sharpe 5" and the little guy is a no-name 2.5". I probably use the little one the most because it will fit in a vise.
