I got these with a bag of stuff at a goodwill type store. I have asked several people but no one seems to know what they are for. There are 8 of them. They aren't sharp or angled to grate so I'm guessing the holes would be for drainage?

The picture doesn't show if the same side of each slot is slanted out and sharpened, much like
a cheese grater's slots. If they are, these things could be lemon or lime zesters.
If your home has a fireplace, you could stack/arrange them ornamentally next to it, and on the
next extra cold night when the utility that normally heats your home (gas, electricity, fuel oil?) fails, well, see how long it takes your friends to notice that the decoration motif around your fireplace has changed!
