I haven't needed this since I sold the 911:
I've got loads of tools from different places that I never use; like a brace (and bits) and a Yankee screwdriver, some ancient electrical diagnosis stuff from my dad, one time tools from harbor freight like a radiator hose loosener, duplicates of combination wrenches that aren't needed...
Right now I'm in the process of building a bespoke travel tool roll - one that I don't have to "build" from my tool chests every time I take a long highway trip, and some of those duplicates are finding a new home.
