Pontiac, I accidentally bought a ruler from England that had inches in tenths. I threw me at first. I was astounded. Now I'm not sure whether it's good or bad.
Matthew, for two or three significant digits I grab my vernier caliper. It's easier. Admittedly, for real precision a digital caliper gives it, but ... it's like the argument between an electronic calculator and a slide rule. The calculator gives a false precision in the answer. I.e. gives seven digits, when only two or three are accurate.
Inferno, by "slide" do you mean the pocket clip, or the slide stops that woodcrafters use? I didn't think General had rulers with slide stops.
