One of my other hobbies is collecting slide rules. Most people aren't
aware that these even *existed*. Whenever it comes up, I have to go
through a whole explanation of what a slide rule is, what it was used
for, etc.
Sitting o n shelf here I have a cylindrical object about the size of
small truncheon. I often ask visitors what it is usef for, I say it's not
a weapon of any kind. So far nobody has figured it out.
It is, of course, an Otis King helical slide rule.
