Did you make a bottle opener Tim? It was a standard piece when it was
still called metalwork in schools. Not PC perhaps now?

I'm young enough that it had shifted its name several times and ended up
as "design and technology: resistant materials technology" and had to
have a syllabus structure largely common with other "D&T" things like
cooking ("edible materials technology"?) that my school didn't do.

Still had the same old teachers, though, teaching us to use the lathes
and milling machine, and we did do both domed and countersunk rivets.
