I hope Joe Blank likes that subject
I’m in seventh heaven. I just got a steel 6" ruler with decimal equivalents of fractions from 1/64 to 63/64 etched on the back! Even better, this rule fits just perfectly in the back of my dial caliper’s case!!! Last night, while reading the New York Public Library Desk Reference (with my caliper snugly in bed with me), I measured the thickness of one page: .004", ten pages: .04", 100 pages: .4". I was just tickled pink.
How about you, what sort of super-anal things do you find yourself doing?
