The short ones [mine was a K&E] went behind the protector in my shirt
pocket that housed 3 mech pencils ... #2, #4, and #4H ... plus a
cartridge fountain pen. I was never fond of the Al Picket rules, they
seem to constantly produce incredibly fine Al dust on my hands, clothes,
and notebooks.
In the mid-60's in SE Asia, just coming out of my bulletproof and
immortal period, I had a Collins Radio circular rule for calculating
tropospheric path parameters. Don't remember where I got it and I was
unaware that Collins was into tropo. It went MIA on a mission somewhere.

I had the same, in 1961. In fact, I had it in a "Quick Draw" holster on my
belt.

I used a 6" Pickett log-log at NC State in the early 60's.
Easier to carry than my full size Post.

OK, you forced me to open my desk drawer all the way and find out what I
had. After climbing over a bunch of mix 31 toroids, a set of Rapidograph
pens, two mechanical drawing sets, ballpoint pens etc., I got to the last
slide rule in the very back of the drawer.
I ended up finding my old 6 inch Pickett & Eckel log-log, a 15cm rule
labeled Hoffman Electronics Corporation made in Denmark, a 12.5 inch
Dietzgen "vector type log log rule" made in the USA that belonged to my
father-in-law, and a Jeppesen CR-1 Flight Computer which is a circular slide
rule 4.25 inches in diameter which calculates fuel consumption, density
altitude, distance traveled given speed, wind problems, etc. And no, I'm not
really interested in selling any of them.
Note that the lengths above are total end-to-end measured lengths.
These all have the glorious attribute that the batteries never run down.
