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.
