What is this a school for ants?
I’m still not convinced that this isn’t just designed for giant pencils. You can sharpen carrots, cucumbers, and probably a lot of other vegetables I don’t know about. Heck, I’d even try this on a pickle. Just don’t put your junk in it. I’m sure you didn’t even think of that but now that you have, don’t do it.
I would be tempted to take this on a survival show and sharpen sticks for hunting. My partner would probably bring something practical like a fire starter and get pissed at me.
