Wire nuts are pretty handy for holding wires together.
What else can they be used for ?

I wonder if they could be used as a pencil lead sharpener : )
Wire nuts are as rare as 4-leafed clovers in the UK. I've only seen them once, when Amazon supplied a couple within a box of parts to connect a Ring doorbell. I binned them, because I had zero experience with them. They look pretty strange to people who have never seen them before, as if they cannot possibly function : ) They are a successful product in North America etc., so I know they must function, but they still look odd, takes some getting used-to.
