Or "better to have them and not need them until you do" tools.
Even though I have scant shop space, I've managed, over the years, to accumulate some tools, mainly hand tools, that justify a home in the shop by being really, really useful every year or so.
Today, I was doing an R&R on the window air conditioner to replace the side wing that I managed to break when putting it in a month ago (never set a heavy, bulky object on a cardboard box that's sitting on a mattress; the box was fine, just a bit tippy; now I've added "repair gouged drywall in guest cottage" to my list). The screws in the little clips that retain the AC unit on the windowsill, and the screws that fasten the side wings to the windowsill, are tight up against the AC unit and the wings, respectively, and it's very hard to get a good grip with a regular Phillips screwdriver, and to turn the driver, because they're so close. In the past, I've just cussed, but today, I remembered this:

Long enough to clear the air conditioner, so I could apply it straight on to the screw head, and turn the handle freely. I can't remember what I paid for it at some yard sale - $1? $2? Regardless, it's well worth it, even if I only ever use it twice a year (AC in for summer/out for winter).
I'm sure y'all have got similar tools: exactly the right tool to do something efficiently that you hardly ever do.
Marie Kondor, or whatever her name is, is not welcome in my shop, thank you.
