I have rules in the shop that indicate that. Not a problem. But still I
asked about a rule indicating 1/2 of 5.3 mm.

I'm pretty sure there are rules that mark .5mm, which is about .020',
which is only .005" more tha 1/64. Your attempt to get someone to
meet your absurd challenge of half of .3mm (.011) on a rule is as
ridiculous as having a scale reading in 128ths. Who could use such a
rule even if someone was stupid enough to make one. Besides, there
are many other ways to measure other than with a rule. None of them
have any use in woodworking. Give it a rest.
