Twenty years ago I bought a Craftsman tape marked in mm on both edges.
It was so much easier and more reliable than fractions for reading and
remembering measurements that I bought a spare.

Eventually, the first one broke. I want to buy a third in case anything
happens to my second one. The only ones I've seen have mm on one edge
only, and that's not as good. Mine is especially good because the marks
for mm 1,4,6, and 9 are shorter than the others, which means I can read
it without counting lines.

Doesn't anyone in America sell metric carpenter's tapes?
