A miniature capstan bar-- the length of my forearm.
A very strong flashlight on a tripod
An ice scraper that daughter gave me that says '#1 mom'
A 14 inch cast iron frying pan, which I probably could not afford to buy new, but which we found in the tall grass behind our first apartment. This was 25 years ago now. We nearly hit it with the lawnmower. Husband cleaned all the rust off with an angle grinder-- I have been using it happily ever since.
There are so many things sold for kitchens-- but these things are actually useful.
