1/10th scales are rare in one way, at say the local hardware, with all graduated fractional or metric. As mwmkravchenko states, and bruce.desertrat observe, they are not extinct. Surveyors and various engineers use them. I have a little 33-272 Stanley graduated in tenths and narrow. Ideal for checks inside tube or through the chuck on barstock in the lathe, handy facing off by relating directly to graduations on the machine. Or buy a loooooong hook rule at 5x the price......maybe 7x
The really small 10 footers, 1/4" wide tapes, in 1/16th's and mm are worth scrounging for. Some converting is needed, but the graduations aren't so fine to make correct measurements difficult. It's additionally helpful fractions and metric divisions don't coincide, pick closest at each instance. Using a straight edge [ie 6" scale] makes an ideal 'pointer' across end of the work, like when threads or chamfers interrupt that plane.
A casual representation of items mentioned;
And speaking of cloth tapes, get one. They are commonly sold among notions for seamstresses; 6'-8' long, dual graduations, unbeatable when measuring circumferences and arcs, in box maybe not a roll-up case, and not expensive.
