And yes, I've used screwdrivers for all those purposes.

I've found a screwdriver to be one of my go-to tools for car work. Oftentimes I need to remove a rubber gasket that's been in the car for years. It's usually completely hardened from heat and baked onto a metal surface. A screwdriver is really useful for scraping that off before I install a new one.

When I worked in a restaurant I saw the line cook do the same with food burned into the salamander.

I can remember using a screwdriver as a hole punch, a paint can opener, a cutting edge to open plastic bags, and a door stop. I'm sure I've used them for other things as well.

When a screwdriver is the only tool handy, you'll often make that work rather than spend the time finding/buying a better tool.

This week I used a screwdriver to pry open the top of a rack mounted server case because it was stuck shut.

you can score many surfaces with a screwdriver, say for measuring to cut wood, or steel, or something.

A prybar.
